The result when the OH- ions go as additional acid is added is that t<span>hey remain in solution but change concentration. </span>This is because when you add more acid to hydroxide, it will change its concentration due to the acidity added.

Answer:

A: They evaporate

Explanation:

Where do the OH- ions go as additional acid is added? They evaporate. They combine with excess H+ ions to form more water. They remain in the solution at the same concentration.

The empirical formula of pyrogallol is C2H2O. Its molar mass is 126 g mol-1. What is the molecular formula?C4H4O2C2H6O3C6H6O3C2H

VARVARA [1.3K]

Answer:

The molecular formula of pyrogallol is: C6H6O3

Explanation:

<u>Step 1:</u> Data given

Empirical formula of pyrogallol is C2H2O

Molar mass of pyrogallol = 126 g/mol

Molar mass of Carbon (C) = 12 g/mol

Molar mass of hydrogen (H) = 1.01 g/mol

Molar mass of oxygen (O) = 16 g/mol

<u>Step 2:</u> Calculate molar mass of the empirical formula

2*12 + 2*1+ 16 = 42 g/mol

<u>Step 3: </u>Calculate the molecular formula

To find the molecular formule , we should multiply the empirical formula by n

n can be found by dividing molar mass of pyrogallol by the molar mass of the empirical formula

n = 126 g/mol / 42 g/mol ≈ 3

We should mulitply the empirica lformula by 3

3*(C2H2O) gives C6H6O3

if we calculate the molar mass now:

6*12 +6*1 + 3*16 = 126 g/mol

The molecular formula of pyrogallol is: C6H6O3

The total daily water use in Mexico is 88 billion m ^ 3 the Mexican population is 127.5 million people. What is the per capita d

eimsori [14]

This problem is providing the water consumption in Mexico as 88 billion m³ and the Mexican population as 127.5 million people so that the per capita daily water use is required and found to be 690 m³/person according to the following:

<h3>Dimensional analysis:</h3><h3 />

In chemistry, the use of dimensional analysis and units conversion covers a wide range of calculations, necessary to report a result in a specific way. In this case, we see this problem asks for the consumption of water, in cubic meters, that each person does every day.

Thus, with a view to calculating this, one must first write this values without any million or billion system as shown below:

$88billion\ m^3=88.000.000.000 m^3 =8.8x10^{10}m^3\\\\127.5million\ people=127.500.000 people=1.275x10^8people$

This means we can get the per capita daily water use by simply dividing these two:

$\frac{8.8x10^{10}m^3}{1.275x10^8people}\\\\= 690\frac{m^3}{person}$
