Answer: The hydrogen ion concentration in molarity is 0.013

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration

Putting in the values:

$pOH=-\log[7.609\times 10^{-13}]$

$pOH=12.1$

Now , $pH+pOH=14$

$pH=14-12.1=1.9$

$pH=-\log [H^+]$

$[H^+]=0.013M$

The hydrogen ion concentration in molarity is 0.013

Which of the following statements provides the BEST explanation for the many chemical similarities between two elements in a Mai

rjkz [21]

Answer:

(b) Both have the same number of valence electrons.

Step-by-step explanation:

We find the most striking chemical similarities between two Main Group elements when they are in the same Group of the Periodic Table.

Elements in the same Group have the same number of valence electrons.

(a) is wrong, because elements in the same group have different masses.

(d) is wrong, because elements in the same Group must be in . different Periods.

This is an incomplete question, here is a complete question.

Hydrogen chloride and oxygen react to form water and chlorine, like this:

$4HCI(g)+O_2(g)\rightarrow 2H_2(g)+2CI_2(g)$

Use this chemical equation to answer the questions in the table below.

Suppose 155. mmol of HCl and 38.8 mmol of O₂ are added to an empty flask. How much HCl will be in the flask at equilibrium?

(1) None.

(2) Some, but less than 155. mmol,

(3) 155. mmol,

(4) More than 155. mmol,

Answer : The correct option is, (1) None

Explanation :

The given balanced chemical reaction is:

$4HCI(g)+O_2(g)\rightarrow 2H_2(g)+2CI_2(g)$

From the balanced chemical reaction, we conclude that

As, 4 mmole of HCl react with 1 mmoles of $O_2$

So, 155. mmole of HCl react with $\frac{155.}{4}\times 1=38.75$ mmoles of $O_2$

That means, $O_2$ is excess reagent and $HCl$ is a limiting reagent. All the moles of HCl will consume.

Hence, the correct option is, None.
