For the reaction PC15 (8) PC13 (g) + Cl2 (g) K = 0.0454 at 261 °C. If a vessel is filled with these gases such that the initial
Fiesta28 [93]

Answer:

The correct answer is B.

The K_{eq} is samller than Q of the reaction . So,the reaction will shift towards the left i.e. towards the reactant side.

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)

The expression for Q is written as:

Q=\frac{[PCl_3][Cl_2]}{[[PCl_5]^1}

Q=\frac{0.20 M\times 2.5 M}{0.20 M}

Q=2.5

Given : K_{eq} = 0.0454

Thus as K_{eq}, the reaction will shift towards the left i.e. towards the reactant side.

The removal of one or more electrons from a neutral atom results in and
Studentka2010 [4]

Answer:

The removal of one or more electrons from a neutral atom results in a cation.

Explanation:

When you remove electrons from a neutral atom, the atom becomes more positive. Electrons have a negative charge and the protons inside of the nucleus have a positive charge. When electrons are removed, the positive charges from the protons outweigh the negative charges. This results in a positively charged atom, called a cation.

A solution is 0.0433 m lif. what is the molarity of the solution if the density is 1.10 g/ml
Otrada [13]

Molarity is the number of moles of solute in one liter of solution whereas molality is the number of moles of solute present in 1 kilo gram of solution.

Molarity is denoted by M and molality denoted by m

m = (n) * (1000 /w_A) = 0.0433 m

M_B = 26 g /mol

W_A = 1 kg = 1000 g

(W_B /26) * (1000 /1000) = 0.0433

W_B = 1.12 g

Mass of solution

W_B + W_A = 1.12 + 1000 = 1001.12 g

Density of solution  = 1.1 g /mL

d = 1.1 = (W_B + W_A) /V  

1.1 = (1001.12) /V

V = 910.11 mL

molarity of solution is:

M = (n) * (1000 /V)

= 0.0433 /0.910 = 0.0474 M

Thus, moalrity of solution is 0.0474 M
