A student wants to determine whether an unknown solid is an ionic compound. He puts some in water and finds that it does not dissolve. He says that this proves the solid is ionic. Which best evaluates the student's reasoning?

A. He is incorrect, because water can dissolve ionic solids.
B. The test proves nothing, because water dissolves all solids.
C. He is correct, because polar liquids cannot dissolve ionic solids.
D. The test proves nothing, because it only shows that the solid is a compound.

(I know water is polar, so I think its a?)

Answers

The student cannot prove that if the compound is ionic or covalent because not all ionic compounds dissolves in water. Some ionic compounds have higher lattice energy results in lower solubility. Thus, option D could be correct.

What are ionic compounds?

Ionic compounds are formed between metals and non metals. Metals are electron rich and they easily donate electrons to the non-metals. Non-metals are generally electronegative and they easily gains electrons from the metals.

Donating electrons make metals acquire positive charge and the non-metals acquire a  negative charge. This charge separation make the compound possess a permanent dipole moment. Which make them easily soluble in water by ion-dipole interaction.

However, some ionic compounds have very strong ionic bonds and their binding energy will be greater so that cannot be easily dissolved in water. For example, AgCl. Therefore, we cannot predict weather the compound is ionic or not by simply noting it solubility in water.

Discribe how an internal combustion engine works. What is drawback to the type of power?

Answers

Answer:

An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber. The force of combustion is converted into mechanical energy through the use of levers and gears. The by products of combustion include energy, water vapor, carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), and carbon monoxide (CO). The two primary drawbacks to the internal combustion engine are the primary energy source is non-renewable (fossil fuels) and the by products can have damaging effects on the environment.

Explanation:

How are renewable fuels different from fossil fuels

Answers

Answer:

Renewable energy

Explanation:

on the other hand, typically emits less CO2 than fossil fuels. In fact, renewables like solar and wind power—apart from construction and maintenance—don't emit any CO2 at all. With renewable energy, you can breathe easier, stay cooler, and create a more comfortable world for generations to come.

Answer:

renewable energy comes from natural resources that can be replenished or replaced during an average human lifetime ; eg, Hydro, solar, wind etc.

fossil fuels can take thousands or even millions of years to naturally replenish; eg, natural gas, coal, oil.

Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.84 × 10^24 C. 4.61 × 10^23 D. 7.87 × 10^23

Answers

Answer:

B

Explanation:

first find the no. Of moles of H2SO4

=  75/98.1

= 0.7645

Next step

In on mole of H2SO4 the no.of oxygen atom is 4.

1 H2SO4 : 4 O

0.7645  : x                     x= 0.7645x4= 3.0581

next multiply avogadros constant

3.0581 x 6.022× 10^23 =1.84x10^24

Mass present in 1 gram of mole substance is called molar mass. Molar mass is calculated by: dividing the mass of the compound in grams by the number of moles present in the substances.

The correct answer is:

option B. 1.84 × 10²⁴

Given,

The mass of sulfuric acid =75.0 g

The molar mass of sulfuric acid = 98.1 g/mol

1.The moles of sulfuric acid can be calculated by

M = m ÷ n

where M is molar mass, m is mass and n moles.

moles of sulfuric acid = mass ÷ molar mass

= 75 g ÷ 98.1 g/mol  

=0.7645 moles

Hence moles of sulfuric acid present is 0.7645 moles.

2. 1 mole of sulfuric acid = 4 oxygen atoms.

Then, 0.7645 moles of sulfuric will contain: 0.7645 × 4 = 3.0581 atoms of oxygen

3. Oxygen atoms present in 75.0 g of H₂SO₄ will be calculated by multiplying it with Avogadro's constant:

= 3.0581 x 6.022× 10²³

= 1.84x10²⁴

Therefore, 1.84 × 10²⁴ oxygen atoms will be found in 75.0 g of H₂SO₄.

The particle represented by X(aq) is


A) H2PO4–(aq)

B) HPO42–(aq)

C) PO43–(aq)

D) H3PO4(aq)

Answers

Answer:

The particle represented by X(aq) is  A) H₂PO₄⁻(aq)

Explanation:

According to the Brønsted-Lowry Theory, a base is a substance capable of accepting protons (H⁺) in solution. Conversely, a substance acts as an acid if it acts as a proton donor.

A proton transfer then occurs, requiring the presence of a proton donor (an acid) and a base that accepts them.

When an acid gives up a proton, it becomes an anion, generating a conjugate base. That is, a conjugate base is an ion or molecule resulting from the acid that loses the proton. Conversely, a conjugated acid is an ion or molecule resulting from the base that the proton gains.

In this NH₃ / NH₄⁺ pair that NH₄⁺ is the conjugate acid of the NH₃ base, the latter acting as a base since it accepts a proton. H₃PO₄ then acts as an acid, yielding a proton and generating the conjugate base H₂PO₄⁻.

So, the particle represented by X(aq) is  A) H₂PO₄⁻(aq)

Cylinder A contains a gas whose molecules have an average speed of 0.0000001 meters/sec. Cylinder B contains a gas whose molecules have an average speed of 0.3 meters/sec. Select the statement below that is true regarding these cylinders. options: Cylinder A contains a gas that has a temperature closest to absolute zero. Even though the molecules are moving at different speeds in the two cylinders, they have the same kinetic energy. Cylinder B contains molecules that are moving more slowly than the molecules in Cylinder A. Cylinder B contains a gas that has a temperature closest to absolute zero.

Answers

Answer:

The correct option is;

Cylinder A contains a gas that has a temperature closest to absolute zero

Explanation:

From the kinetic theory of gases, the average speed of a gaseous molecule is found from the following equation;

[tex]v_{rms} = \sqrt{\frac{3\cdot R \cdot T}{MW} }[/tex]

Where:

[tex]v_{rms}[/tex] = rms speed which is the square root of the average of the velocities of the gas molecules squared which is used in place of the average of the gas molecules as the sum of the velocities of all the gas molecules in the cylinder is zero

R = Universal gas constant = 8.3145 J/(mol·K)

MW = Molecular weight of the gas

Hence where we have;

[tex]v_{rmsA}[/tex] = Average velocity of gas A = 0.0000001 m/s

[tex]v_{rmsB}[/tex] = Average velocity of gas B = 0.3 m/s

Since, R and MW are constant for the gas in cylinder A constant, therefore, as [tex]v_{rmsA}[/tex] ≈ 0 m/s, the temperature, [tex]T_A[/tex], of gas A is closest to absolute zero.

Explain the effects that different frequencies of electromagnetic radiation have when absorbed by matter.

Answers

In order to answer this question we might first want to think about what is electromagnetic radiation. In essence it’s light, just some of the wavelengths are too long or too short for us to see.

We can think about it as two oscillating sinusoidal (goes up and down) waves, one is electric, the other is magnetic.

Because we’re dealing in waves, that means we can calculate their frequency, wavelength, amplitude (brightness) and period.

To calculate it we can use E=hc/lambda
Where E = jewels of energy
h = Planck’s constant
c = speed of light
Lambda = wavelength

It doesn’t really matter for this question what those things mean, just note that it takes more energy to have a shorter wavelength, or less energy to have a longer wavelength.

So now we can answer the question. Light of a longer wavelength has less energy than that of a shorter wavelength. So, when long wavelengths are absorbed by matter (atoms) they will give those atoms less energy. So, either it will pass through the object entirely or it will make the atoms vibrate a little bit more than they already are and we call that thermal energy, or heat.

If high energy wavelengths are passing through matter then they will be giving those atoms a lot of energy, sometimes even ionizing the atoms.
Which, if you’re a living thing can be very bad for your cells.

I hope that helps.

As the frequency of the radiation increases further, into the visible light spectrum, it can cause electronic transitions in atoms and molecules, leading to the emission of light and other optical effects.

What is electromagnetic radiation?

Electromagnetic radiation is a form of energy that travels through space in the form of waves, without the need for a medium to propagate. It is characterized by oscillating electric and magnetic fields that are perpendicular to each other and the direction of propagation.

At low frequencies, such as radio waves and microwaves, the radiation typically only causes heating of the matter, as it transfers energy to the molecules in the material.

At higher frequencies, such as infrared radiation, the radiation can cause vibrations in the atoms and molecules of matter, leading to heating and thermal effects.

Thus, When matter absorbs electromagnetic radiation, the effects that it has on the matter depend on the frequency of the radiation.

10) Intravenous saline solutions have a concentration of 1.5 M NaCl. How many liters of saline can be prepared from 50.0 g of NaCl?

Answers

Answer:

0.57 mol/L

Explanation:

Molarity (M) is defined as the number of moles of solute per liter of solution (moles/Liter).

Molarity  =  [tex]\frac{moles of solute}{liters of solution}[/tex] or Moles  =  molarity × litres

so, the mass of Nacl in 1 mol is 58.44 g,

Moles of NaCl = 50.0g x 1 mole NaCl / 58.44 g

                          = 0.855 mol NaCl

Moles  =  molarity × litres

0.855 = 1.5 M x L

L = 0.57 mol/L

Hence, 0.57 mol/L can be prepared from 50.0 g of NaCl.
