Answer:

CH₂

Explanation:

Given parameters:

Percentage composition:

Carbon = 40.1%

Hydrogen = 6.6%

Unknown:

Empirical formula of the compound = ?

Solution:

The empirical formula of a substance is its simplest formula.

Elements Carbon Hydrogen

Percentage

Composition 40.1 6.6

Molecular mass 12 1

Number of moles 40.1/12 6.6/1

3.342 6.6

Divide through by

the smallest 3.342/3.342 6.6/3.342

1 2

So the empirical formula of the compound is CH₂

BartSMP [9]

Answer: The given statement is TRUE.

Explanation:

An equilibrium reaction is one in which rate of forward reaction is equal to the rate of backward reaction.

Equilibrium constant is defined as the ratio of the product of the concentration of products to the product of the concentration of reactants each raised to their stochiometric coefficient.

For example for the given equilibrium reaction;

$2H_2O(g)\leftrightharpoons 2H_2(g)+O_2(g)$

$K_{eq}=\frac{[H_2]^2[O_2]}{[H_2O]^2}$

Thus the given statement that in calculating the equilibrium constant for a reaction, the coefficients of the chemical equation are used as exponents for the factors in the equilibrium expression is True.

What is the minimum cation-to-anion radius ratio (rC/rA) for an octahedral interstitial lattice site?

mash [69]

Answer:

0. 414

Explanation:

Octahedral interstitial lattice sites.

Octahedral interstitial lattice sites are in a plane parallel to the base plane between two compact planes and project to the center of an elementary triangle of the base plane.

The octahedral sites are located halfway between the two planes. They are vertical to the locations of the spheres of a possible plane. There are, therefore, as many octahedral sites as there are atoms in a compact network.

The Octahedral interstitial void ratio range is 0.414 to 0.732. Thus, the minimum cation-to-anion radius ratio for an octahedral interstitial lattice site is 0. 414.
