Answer:

Reaction proceeds to the left toward the reactants.

Explanation:

Hello,

In this case, since the reaction is:

2NOCl (g) \rightleftharpoons 2NO(g) + Cl_2 (g); Keq= 4.4 x10^{-4}

For the given amounts, one computes the reaction quotient:

Q=\frac{[NO]^2[Cl_2]}{[NOCl]^2} =\frac{(0.500M)^2(0.500M)}{(1.00M)^2} =0.125

Thus, since Q>Keq, the reaction will form more NOCl in order to increase its concentration and therefore reestablish the equilibrium, for that reason the answer is reaction proceeds to the left toward the reactants.

Regards.

In a reaction, chlorine accepts an electron to form Cl-. What is true about the atomic size of the chlorine ion?
Lynna [10]

Answer is: The atomic size of the chlorine ion is larger than the size of the chlorine atom.

Covalent radii of chlorine atom (Cl) is 0.099 nm and ionic radii of chlorine anion (Cl⁻) is 0.181 nm.

Difference between an chlorine atom and chlorine anion is the number of electrons that surround the nucleus.

Chlorine atom has 17 electrons and chlorine anion has 18 electrons.

How many moles of neon atoms are there in a neon sign that has 2.4 * 20^ 24 atoms of neon? *
Whitepunk [10]

Answer:

4 moles of neon

Explanation:

Given data:

Number of moles of neon = ?

Number of atoms of neon = 2.4×10²⁴ atoms

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For given neon atoms:

1 mol =  6.022 × 10²³ atoms

2.4×10²⁴ atoms × 1 mol / 6.022 × 10²³ atoms

0.4×10¹ mol = 4 mol

Solid lead IV oxide decomposes into solid lead and oxygen gas.
vredina [299]
The balanced equation for the decomposition of solid lead iv oxide is as follows: 2PbO2 = 2PbO + O2.
Lead IV oxide decompose to give lead ll oxide and oxygen. Lead iv oxide is thermally unstable and it usually decomposes into oxygen and lead ll oxide when heated. Lead ll oxide is more stable than lead lV oxide.

In the process of eating, what kind of energy in food is transformed into heat energy by your body?
Rama09 [41]

Answer:The chemical energy

Explanation:because The chemical energy in the food you eat is changed into another kind of chemical energy that your body can use. Your body then uses that energy to give you the kinetic energy that you use in everything you do.
