Why does reactivity decrease as you move from left to right on the periodic table?

Answers

Answer 1

Higher reactivity is caused by the ease with which electrons can be given or taken away as you move further to the left and down the periodic chart.

How quickly a substance performs a chemical reaction is measured by its reactivity. A release of energy is typically present during the reaction, which might involve the chemical alone or in combination with other atoms or molecules. Chemistry's notion of reactivity is not entirely clear. In other words, whether a substance reacts at all and how quickly it reacts, it seems to incorporate both thermodynamic and kinetic aspects. Both factors which are distinct in reality are frequently temperature-dependent.

A subatomic particle called an electron has an electric charge that is one element's negative opposite. A negatively charged, subatomic particle known as an electron can be either attached to or liberated from an atom. There are three main types of particles in an atom: protons, neutrons, and an electron that is bonded to an atom.

What is balanced chemical equation?

A chemical equation is said to be balanced chemical equation if the atoms or molecules of different elements on the reactant side is equal to the atoms or molecules of different elements on the product side.

In the given reaction, HCl is reactant and Ca(OH)2 is base. They react with each other to form CaCl2 and release two molecules of H2O.

Now, we will balance the chemical equation.

On reactant side, there are 3 atoms of hydrogen atoms, one atom of chlorine, two atom of oxygen and one calcium atom. So, we equal it by reacting two molecules of HCl with one molecule of Ca(OH)2 to form one molecule of CaCl2 and two molecules of water.

Therefore, by balancing equation we get

2HCl(aq)+Ca(OH)2 ------ CaCl2 + 2H2O

Thus, we concluded that the balanced chemical equation for acid-base reactions is as given below:

Is CO2 polar or nonpolar covalent bond?

Answers

Due to its symmetry and the fact that the pull of the two oxygen atoms on the electrons of carbon cancel each other out, carbon dioxide is a nonpolar molecule with polar bonds. Because the vector sum of the dipole moments of the two CO bonds is zero, the CO2 molecule is non-polar even if the CO bond in it is polar.

With carbon, each oxygen atom forms a double bond. Different electronegativities of carbon (C) and oxygen (O) result in unequal distribution of electrons between them. Due to the cancellation of the two bond dipole moments, there is no net molecule dipole moment. Carbon dioxide is a non-polar gas as a result.

Which statement correctly explains how matter is conserved in chemical reactions?

Answers

The statement which correctly explains how matter is conserved in chemical reactions is- Atoms of each element are conserved, so the total mass does not change.

The Law of Lomonsov-Lavoisier and the Law of Conservation of Mass are other names for the Law of Conservation of Matter. "The mass is not generated or destroyed, simply altered," according to this law.

As a result of the diverse atomic arrangements in the various substances, the reagents interact with one another to create new products that differ from the reagents in terms of their physical and chemical characteristics. But the amount of matter or mass before and after a transformation (chemical reaction) must always be constant; that is, the amounts of the masses involved in a given reaction must not change in their proportions when the reaction is complete.

n other words, the mass prior to the chemical reaction and the mass following the reaction are equal. Nuclear reactions are the exception to the norm, where it is possible to change mass into energy and vice versa.

A sample of gas contains 0.1500 mol of N2(g) and 0.3000 mol of H2(g) and occupies a volume of 16.2 L. The following reaction takes place:

N2(g) + 2H2(g)N2H4(g)

Calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.

Answers

The volume of the sample after the reaction takes place at constant temperature and pressure would be 5.4 L.

Volume of gases at constant temperature and pressure

In the reaction: [tex]N_2(g) + 2H_2(g)-- > N_2H_4(g)[/tex]

Stoichiometrically, 1 mole of [tex]N_2[/tex] reacts with 2 moles of [tex]H_2[/tex] to produce 1 mole of [tex]N_2H_4[/tex].

In reality, 0.1500 mol of  [tex]N_2[/tex] reacts with 0.3000 mol of [tex]H_2[/tex]. The equivalent amount of [tex]N_2H_4[/tex] that would be formed will be 0.1500 mol according to the mole ratios from the balanced equation of the reaction.

Now, at constant temperature and pressure:

0.1500 + 0.3000 = 0.4500 mol

0.4500 mol is equivalent to 16.2 L according to the illustration.

0.1500 mol of  [tex]N_2H_4[/tex] is produced, the equivalent mole would, therefore, be:

0.4500 mol = 16.2 L

0.1500 mol = 16.2 x 0.1500/0.4500

                  = 5.4 L

Answers

The partial pressure A is 6.14 and that of  of B is 5.89 atm Thus the mole fraction of B is 0.49.

What is mole fraction?

Mole fraction of a component in a mixture is the ratio of its number of moles to the sum of number of moles all the components in the mixture.

The mole fraction of a gas if their partial pressures are given is the ratio of its partial pressure to the total pressure of the mixture. Here the partial pressure of A is 6.14 and that of B  is 5.89 atm.

The mole fraction of B = Pb/ (Pa + Pb)

                                      = 5.89 atm  / (6.14 + 5.89 atm)

Answers

Considering the Boyle's law, the volume of the gas sample will be 997.908 mL.

Boyle's law

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: if the pressure increases, the volume decreases while if the pressure decreases, the volume increases.

Mathematically, this law expresses that if the amount of gas and the temperature remain constant, the product of the pressure by the volume always has the same value:

P×V= k

where P is the pressure, V is the volume, and k is a constant.

Analyzing an initial state 1 and a final state 2, it is fulfilled:

P₁×V₁= P₂×V₂

New volume in this case

In this case, you know:

P₁= 1.10 atm

V₁= 694 mL

P₂= 0.765 atm

V₂= ?

Replacing in Boyle's law:

1.10 atm× 694 mL= 0.765 atm×V₂

(1.10 atm× 694 mL)÷ 0.765 atm= V₂

The formula of the hydrated potassium carbonate salt is K₂CO₃.2H₂O

Based on the calculated mass ratio of carbon and oxygen in carbon dioxide, carbon has a fixed composition.

What are hydrated compounds?

Hydrated compounds are compounds that contain one or more molecules of water physically combined with a molecule of the compound.

The formula of the hydrated potassium carbonate salt is determined as follows:

Mass of the hydrated sample = 10.0 g

Mass of anhydrous salt = 7.83

mass of water = 10 - 7.83

mass of water = 2.17 g

Molar mass of water = 18.0 g

Molar mass of anhydrous potassium carbonate = 138 g

moles of anhydrous potassium carbonate in sample = 7.83/138

moles of anhydrous potassium carbonate = 0.056 moles

moles of water in the hydrated salt = 2.17/18

moles of water in the hydrated salt = 0.12

Mole ratio of water to anhydrous salt = 0.12/0.056

Mole ratio of water to anhydrous salt = 1 : 2

Formula of hydrated salt = K₂CO₃.2H₂O

The mass ratio of carbon to oxygen in the compounds is given below:

Sample 1:

nitrate is dissolved in it.
Round your answer to 3 significant digits.
M

Answers

Final Molarity of barium ion = 0.127 M.

We first assume the reaction goes to completion and that the volume. of the reaction doesn't change.

The balanced stoichiometric equation is

Ba(NO3)2(aq) + (NH4)2SO4(aq) = BaSO4(s) + 2NH4NO3(aq)

irst of, we need to check which reactant is in excess and which one is completely used up in the reaction. To do this, we fimd the number moles of each reactant at the start of the reaction.

For Ba(so4)₂

Number of moles = (Mass)/(Molar Mass)

Mass of Barium nitrate = 9.91 g

Molar mass of Barium nitrate = g/mol

Number of moles = (9.91/261.337) = 0.038 moles.

For NH₄NO3,

Number of moles = (Concentration in mol/L) × (Volume in L)

Concentration of Ammonium surface in mol/L = 0.50 M

Volume in L = (300/1000) = 0.3 L

Number of moles = 0.50 × 0.3 = 0.15 moles

From the stoichiometric balance of the reaction,

1 mole of Ba(NO3)₂ reacts with 1 mole of BaSO₄

Hence, it is evident that it is Ba(NO3)₂ that is the limiting reagent; the chemical specie that is used up in the process of the reaction and it determines the amount of other reactants required & products formed.

1 mole of Ba(NO3)₂ gives 1 moles of 0.038 moles of BaSO4(s) will give 1× 0.038 moles is The molarity of Ba(SO4) Then given as (number of moles) ÷ (Vol in L)

Number of moles = 0.038moles

Volume of the solution in L = 0.3 L

Molarity of BaSO4  = (0.038/0.3)

= 0.127 M

Note that 1 mole of Ba(SO4)contains 1 mole of Ba+2 ion

Hence, 0.127 M of Ba(SO4) also contains 0.127 M of Ba+2 ion.
