D. Add an appropriate amount of sodium hydroxide.

Usually, chemical processes require an optimum pH. This is the pH at which the desired chemical conversion gives  the maximum yield.

As we can see, the pH of the system is much higher than the optimum pH. We can decrease the pH to the optimum pH of 5.0 by adding an appropriate amount of  a base such as NaOH.

Hence, the pH can be brought to 5.0 from 6.5 by adding an appropriate amount of NaOH.

Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.8
Margarita [4]

Answer:

B

Explanation:

first find the no. Of moles of H2SO4

=  75/98.1

= 0.7645

Next step

In on mole of H2SO4 the no.of oxygen atom is 4.

1 H2SO4 : 4 O

0.7645  : x                     x= 0.7645x4= 3.0581

next multiply avogadros constant

3.0581 x 6.022× 10^23 =1.84x10^24

How many moles of CuO are needed to react with 5.9 moles of CO2
Likurg_2 [28]

Answer:

If 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.

Explanation:

The balanced reaction is:

CuO + CO₂ → CuCO₃

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • CuO: 1 mole
  • CO₂: 1 mole
  • CuCO₃: 1 mole

You can see that the stoichiometric relationship between CuO and CO₂ is 1: 1. In other words, for each mole of CuO that reacts, one mole of CO₂ will also react.

So <u><em>if 5.9 moles of CO₂ react, 5.9 moles of CuO will also react.</em></u>
