Answer:

The grains of sedimentary rock are cemented together and form an interlocking texture.

Explanation:

The sedimentary rocks are formed by deposition of minerals from the ocean or sea waters lashed to the land shore. The deposition of minerals for a long time followed by cementation of them by the grains lead to the formation of sedimentary rocks.

The grains of the sedimentary rocks are very small in size and they are cemented together. The grains are present in the matrix of cement while the pores of the matrix are filled with grains of minerals like an interlocking texture.

The above reaction is run and found to follow second order kinetics with a rate constant of 1.30 x 10-3 M-1sec-1. If the initial

Leya [2.2K]

The final concentration after 172 seconds is 1.15 M. To obtain this answer, use the the integrated rate law for the order of reaction. Based on the problem, this is a second order reaction. The units of the rate constant also support that it is a second order reaction.

Further Explanation:

The solution to this problem is straightforward.

Identify the integrated rate law for the corresponding order of reaction.
Substitute the given values into the integrated rate law equation.
Use algebra to solve for the unknown, C(f).

STEP 1: Since the reaction is a second order reaction, the integrated rate law will be:

$\frac{1}{C_{f}} = \ kt \ + \frac{1}{C_{i}}$

where:

C(f) is the final concentration

k is the rate constant

t is the time

C(i) is the initial concentration

STEP 2: Plugging in the values given in the problem into the equation, the following equation should be obtained:

$\frac{1}{C_{f}} \ = (1.30 \ x \ 10^{-3} \frac{ \ 1 }{ \ M-s})(172 \ s) \ + \ \frac{1}{1.54 \ M} \\$

STEP 3: Using algebra to solve for C(f):

$\frac{1}{C_{f}} = \ 0.87295\\ \\C_{f} = \ 1.14554 \ M$

Since the given values only have 3 significant figures, the final answer must be expressed with 3 significant figures as well.

Therefore,

$\boxed {C_{f}\ = \ 1.15 \ M}$

Sodium oxide decomposes to produce oxygen gas and sodium metal

AlexFokin [52]

Answer:

2Na2O (s) → 4Na (s) + O2 (g)

Explanation:

According to this question sodium oxide, Na2O, decomposes to produce oxygen gas, O2, and sodium metal, Na. The following represents the chemical equation;

Na2O (s) → Na (s) + O2 (g)

However, the above chemical equation is not balanced as the number of atoms of each element on both sides are not equal e.g. there are 2 moles of Na on one side and 1 mole on the other.

To balance the equation, we make use of coefficients to ensure that the atoms of each element on the reactant side are the same as that on the product side. The balanced equation is as follows:

2Na2O (s) → 4Na (s) + O2 (g)
