Answer:

Nitrogen

Explanation:

The element nitrogen cannot be a product in the given reaction.

The reaction is;

HCl + CaCO₃

According to the law of conservation of matter, "matter is neither created nor destroyed in the cause of a chemical reaction".

The law suggests that, in a chemical reaction, we end up with the same species we started with. Although due to rearrangement of bonds, new compounds can form;

Starting atoms

These species will also be found in the product.

The polarity of the water molecule aids in dissolving compounds. This is demonstrated by all but which statement?A)The water mol

never [62]

Answer:

The correct option is;

A) The water molecules group together in clumps.

Explanation:

To answer the question, we look at each option as follows

A) The water molecules group together in clumps

This does not aid dissolution of compounds as clumping excludes non polar molecules, making them less soluble.

B) The partial negative oxygen atom end of the water molecule surround cations.

When an ionic compound such as NaCl is dissolved in water, the oxygen atoms surround the positive Na⁺ cations in the solution.

C) The partial positive hydrogen atom end of the water molecule surround anions

When the ionic NaCl compound is dissolved in water, the hydrogen atoms surround the negative Cl⁻ anions in the solution.

D) The water molecules also dissolve nonelectrolytes by creating a hydration sphere around the molecule.

Water is able to dissolve nonelectrolytes by creating an hydration sphere or hydration shell around the molecule.

For the simple decomposition reactionAB(g)→ A(g) + B(g)Rate =k[AB]2 and k=0.2 L/mol*s . How long will it takefor [AB] to reach 1

mixer [17]

Answer:

6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.

Explanation:

$Rate = k[AB]^2$

The order of the reaction is 2.

Integrated rate law for second order kinetic is:

$\frac{1}{[A_t]} = \frac{1}{[A]_0}+kt$

Where, $[A_0]$ is the initial concentration = 1.50 mol/L

$[A_t]$ is the final concentration = 1/3 of initial concentration = $\frac{1}{3}\times 1.50\ mol/L$ = 0.5 mol/L

Rate constant, k = 0.2 L/mol*s

Applying in the above equation as:-

$\frac{1}{0.5} = \frac{1}{1.50}+0.2t$

$\frac{1}{1.5}+0.2x=\frac{1}{0.5}$

$t = 6.66\ s$

<u>6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.</u>
