Answer:
one mole of HgO will give one mole of Hg.
Explanation:
Given data:
Moles of HgO = 1 mol
Moles of Hg = ?
Solution:
Chemical equation:
2HgO → 2Hg + O₂
Now we will compare the moles of Hg with HgO from balance chemical equation.
HgO : Hg
2 : 2
1 : 2/2×1 = 1 mol
So, one mole of HgO will give one mole of Hg.
Since greenhouses are designed to trap in heat, we call global warming the “greenhouse effect” because it essentially does the same thing. “Greenhouse” gases (gases that easily trap heat) clog up the outer layers of the atmosphere and prevents heat from leaving the planet. The gases trap heat, just like greenhouses.

Answer:
OCl− + H2O ⇌ HOCl + OH−
Explanation:
Sodium hypochlorite is a corrosive base with pH 13, that will react with water in a neutralization process to finally obtein hypochlorous acid. This acid has a great disinfectant effect in water.
Answer:
150.0 mL.
Explanation:
- It is known that the no. of millimoles of HNO₃ before dilution = the no. of millimoles of HNO₃ after dilution.
∵ (MV) before dilution = (MV) after dilution.
<em>∴ V before dilution = (MV) after dilution / M before dilution</em> = (0.15 M)(500.0 mL)/(0.50 M) = <em>150.0 mL.</em>
