What does the VSEPR theory describe

Answers

Answer:

The shape of a molecule based on the number of electron pairs on the valence shell of its central atom

Explanation:

The improvement of the Sidgwick-Powell theory came to be known as the Valence Shell Electron Pair Repulsion theory (VSEPR). This theory approaches the determination of molecular shape from the perspective of the number of electron pairs on the valence shell of the central atom in the molecule.

Electron pairs on the valence shells of atoms leads to repulsion. Repulsion between two lone pairs is greater than repulsion between a lone pair and a bond pair which is also greater than repulsion between two bond pairs.

Lone pairs cause more repulsion, hence they distort molecules from the ideal shape predicted based on their electron domain geometry.

Which of the following processes is exothermic? Group of answer choices Allowing meat to thaw after taking it out of the freezer Popsicle melting on a warm summer day Boiling water in a beaker to convert it to steam Rolling a ball up a hill Reacting hydrogen and oxygen gases to make water

Answers

Answer:

Reacting hydrogen and oxygen gases to make water

Explanation:

Exothermic means that energy is released into the environment, so let's go through the process of elimination.

Allowing meat to thaw after taking it out of the freezer - NO it is endothermic, and takes energy/heat from the environment to thaw.

Popsicle melting on a warm summer day - NO also endothermic, the opposite of exothermic.

Boiling water in a beaker to convert it to steam - NO because we need to add heat, so it doesn't release any energy.

Rolling a ball up a hill - NO, for a ball to roll up a hill, it needs energy from something else, so it's not exothermic.

Reacting hydrogen and oxygen gases to make water - YES this reaction makes new bonds, which releases energy, so this is exothermic.

Among the following choices reacting hydrogen and oxygen gases to make water is an exothermic reaction as it releases energy as new bonds are formed.

What is an exothermic reaction?

An exothermic reaction is defined as a chemical reaction which involves release of energy in the form of light,heat .In these reactions, energy is transferred from system to surroundings rather than taking energy from surroundings into system as in endothermic reactions.

In an exothermic reaction,change in enthalpy is negative.Therefore, it can be inferred that net amount of energy which is required to start the exothermic reaction is less than the net amount which is released by the reaction.

Examples of exothermic reactions are combustion reactions, detonation of nitroglycerin , neutralization reactions and nuclear fission.

calculate the amount in moles of a gas which occupies 250cm3 at s.t.p​

Answers

Answer: 0.01 moles (I am guessing)

Explanation:

Firstly, cm3 and ml are equal to one another, therefore 250cm3 can also be written as 250 ml. I Googled and found that ideally, one mole of gas will occupy a volume of 22.4 L (22,400 ml) at s.t.p. 250 ml out of 22,400 ml is 0.01 rounded, therefore I assume that is the answer. About 0.01 mole occupies 250 cm3 at s.t.p.

How would a decrease in volume affect the following reaction? N2 (g) + O2 (g) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. 2NO(g) (1 point) The equilibrium would shift to the right. The equilibrium would shift to the left. There would be no change to equilibrium. The affect on equilibrium cannot be determined.

Answers

Answer:

Explanation:

                        N₂(g) + O₂(g) ⇄ 2NO( g )

We shall apply Le Chatelier's principle to see the effect of decrease in volume or increase in concentration on the effect of state of equilibrium in the reaction given .

In this reaction 1 volume of nitrogen gas reacts with 1 volume of oxygen to give 2 volume of NO gas . In total there is no change in volume due to reaction . So when we change the volume , the concentration of reactant and product will affect the rate of forward and reverse reaction . Overall there will be no change in the state of equilibrium . The equilibrium will neither shift to the right nor will shift to the left.

It will remain unchanged .

Since we can estimate the last digit I would say that the length of the cylinder is 2.76cm. Since I am estimating any number 2.72cm or 2.78cm could also be correct.

Why would 2.755 not be a correct measurement according to estimating the last digit?

Answers

Answer:

The accuracy of the measuring ruler is given as tenth of a centimetre and given that the image above the ruler is measuring in between a tenth of a centimetre, it is therefore measuring at a higher accuracy than the ruler

calculate the pH of 500cm3 of 0.2mol/dm3 Ca(OH2), assume complete ionisation​

Answers

Answer:

The pH of 500 cm³, 0.2 mol/dm³, Ca(OH₂) is ≈ 13.6

Explanation:

The given parameters are;

Concentration of the calcium hydroxide, Ca(OH₂) = 0.2 mol/dm³

Volume of the calcium hydroxide, Ca(OH₂) = 500 cm³

Given that the calcium hydroxide, Ca(OH₂),  undergoes complete ionization in water, complete dissociation, we have;

Ca(OH₂)  ⇄  Ca²⁺ + 2 OH⁻

Therefore, we have;

2 moles of [OH⁻] for each mole of Ca(OH₂) which gives the concentration of  [OH⁻] as

[OH⁻] = 2 × 0.2 ≈ 0.4 mol/dm³

The pH is given by the formula

pH = 14 + ㏒₁₀ [OH⁻]

pH = 14 + ㏒₁₀ (0.4) = 14 - 0.3979 = 13.6021 ≈ 13.6

The pH of the 500 cm³ 0.2 mol/dm³ Ca(OH₂) ≈ 13.6.

Why are ionic crystals soluble in water?

A. The covalent bonds in the ionic crystal can easily reshape to bond with the water molecules, allowing it to dissolve.

B. The water slides the layers of the ionic crystal lattice so that positive charges line up with positive charges. They repel

each other and break the crystal apart.

C. Partial charges in water molecules attract the charges in the atoms of the ionic crystal, pulling the atoms off the crystal.

D. They are not. The positive and negative charges in the ionic lattice are stronger than the partial charges in the water.

Answers

Answer:

C. Partial charges in water molecules attract the charges in the atoms of the ionic crystal, pulling the atoms off the crystal.

Explanation:

Water consists of partial positive and hydrogen ions and partial negative oxygen ions. The ionic crystals also dissociate into ions when in water.These partial charges and ability of ionic compounds to dissociate in water are the main reason why ionic crystals dissolve in water.

The partial charges in the water molecules form a strong attraction towards the charges in the atoms of ionic crystals. This then pulls the atoms from the crystals and ends up in the dissolution of the ionic crystals.

Di- Ethyl zinc is a chemical used in the library to protect books from worms, its composition is 53% Zinc, 38.9% Carbon, and 8.1% Hydrogen (At mass of Zn=65.4, C=12, H=1). Find the empirical formula of a compound

Answers

Answer:

ZnC4H10

Explanation:

The empirical formula of a compound refers to the formula that gives the simplest whole number ratio of each atoms of the elements in the compound.

The empirical formula is calculated thus:

The given percentages in the question represent the mass in grams of each element in the compound.

Zinc= 53%, C= 38.9%, H= 8.1% which represents 53g, 38.9g and 8.1g of each element respectively.

Molar Mass of Zn= 65.4 g/mol

Molar Mass of C= 12 g/mol

Molar Mass of H= 1 g/mol

Step 1: Divide the mass of each element by the molar mass given to convert to moles:

Zn= 53/65.4 = 0.81moles

C= 38.9/12 = 3.24moles

H= 8.1/1 = 8.1moles

Step 2: Divide each mole value by the smallest number of moles calculated, which is 0.81moles:

Zn= 0.81/0.81 = 1

C= 3.24/0.81 = 4

H= 8.1/0.81= 10

This is the mole ratio represented in the subscript of each element in the empirical formula:

That is, Zn (1) C (4) H (10)

Empirical formula= ZnC4H10

Born on August 26, 1918 in West Virginia, Johnson had a gift for numbers. As Johnson later described, she spent her life countingcounting the steps she walked, the dishes she washed. Anything that could be counted, I did, she once said. School came easily for Johnson, and she completed eighth grade by the age of 10. After that, she couldnt continue learning locally because her county denied African American students access to secondary education. Johnsons father, Joshua, moved the family 120 miles away so she could attend high school. By 18, she graduated with honors from West Virginia State College, receiving degrees in mathematics and French. She then went on to teach these subjects at a public school. After teaching for many years, one job posting changed the arc of her life. The National Advisory Committee for Aeronautics (NACA) was looking to hire women to fill unique positions. The job title: Computer. Based at Langley Research Center, these human calculators checked the math done by NACAs male engineers and mathematicians. Johnsons sharp intellect and resourcefulness were quickly recognized at Langley; she was promoted after only two weeks. Nonetheless, Johnson faced barriers at the agency. At the time, many workplaces werent integrated, and Johnson and her African American colleagues were segregated within an area of Langley named West Computers. Regardless, she steadfastly asked questions and made her voice heard. In 1958, NACA began to focus more on space travel, and the agency was newly dubbed the National Aeronautics and Space Administration (NASA). Johnsons career flourished at NASA. In 1961, Johnson plotted astronaut Alan Shepards path into space. Then in 1962, Johnson helped astronaut John Glenn to be the first American to orbit the Earth. Even though NASA had started using electronic computers, Johnson was the one to double-check the machines calculations before blast-off. Additionally, Johnson contributed to Apollo 11s milestone 1969 moon landing. She also helped Apollo 13 return safely home after an equipment malfunction. Later in her career, Johnson worked on calculations for NASAs space shuttles and satellites. Even with such stellar contributions, many people in America didnt know Johnsons name until long after her retirement. In 2016, writer Margot Lee Shetterly published Hidden Figures, a chronicle of Johnson and two of her fellow mathematicians work at NASA.

Consequently, she has proposed the following accounting changes in connection with Mathys Inc.'s 2017 financial statements.1. At December 31, 2016, the client had a receivable of $820,000 from Hendricks Inc. on its balance sheet. Hendricks Inc. has gone bankrupt, and no recovery is expected. The client proposes to write off the receivable as a prior period item.2. The client proposes the following changes in depreciation policies.(a) For office furniture and fixtures, it proposes to change from a 10-year useful life to an 8-year life. If this change had been made in prior years, retained earnings at December 31, 2016, would have been $250,000 less. The effect of the change on 2017 income alone is a reduction of $60,000.(b) For its new equipment in the leasing division, the client proposes to adopt the sum-of-the-years'-digits depreciation method. The client had never used SYD before. The first year the client operated a leasing division was 2017. If straight-line depreciation were used, 2017 income would be $110,000 greater.3.In preparing its 2016 statements, one of the client's bookkeepers overstated ending inventory by $235,000 because of a mathematical error. The client proposes to treat this item as a prior period adjustment.4. In the past, the client has spread preproduction costs in its furniture division over 5 years. Because its latest furniture is of the "fad" type, it appears that the largest volume of sales will occur during the first 2 years after introduction. Consequently, the client proposes to amortize preproduction costs on a per-unit basis, which will result in expensing most of such costs during the first 2 years after the furniture's introduction. If the new accounting method had been used prior to 2017, retained earnings at December 31, 2016, would have been $375,000 less.5. For the nursery division, the client proposes to switch from FIFO to LIFO inventories because it believes that LIFO will provide a better matching of current costs with revenues. The effect of making this change on 2017 earnings will be an increase of $320,000. The client says that the effect of the change on December 31, 2016, retained earnings cannot be determined.6. To achieve an appropriate recognition of revenues and expenses in its building construction division, the client proposes to switch from the completed-contract method of accounting to the percentage-of-completion method. Had the percentage-of-completion method been employed in all prior years, retained earnings at December 31, 2016, would have been $1,075,000 greater.Instructions(a) For each of the changes described above, decide whether:(1) The change involves an accounting principle, accounting estimate, or correction of an error.(2) Restatement of opening retained earnings is required.(b) What would be the proper adjustment to the December 31, 2016, retained earnings?
