I would say that La Nina is responsible for dry conditions in California and typically it is the year after La Nina that the dryness turns often to severe drought. Drought can be bad for agriculture requiring a lot more irrigation and posing a drain on water resources which decrease also during a drought,
Answer:
Geothermal energy has a faster rate because a vast amount of heat energy is always present inside Earth's core.
Geothermal energy has a slower rate because the water present below Earth's surface cools down periodically

Answer:
See explanation
Explanation:
a) The equation of the reaction is;
2Na + Cl2 ------>2NaCl
Number of moles of sodium = 10g/23 g/mol = 0.43 moles
If 2 moles of sodium reacts with 1 mole of Cl2
0.43 moles reacts with 0.43 * 1/2 = 0.215 moles of Cl2
Mass = 0.215 moles of Cl2 *71 g/mol = 15.265 g
b) Equation of the reaction;
HgO -> Hg + O2
1.252 moles of HgO 1.252/32 gmol = 0.039 moles
1 mole of HgO yields 1 mole of oxygen hence
0.039 moles of HgO yields 0.039 moles of oxygen
Mass of oxygen = 0.039 moles * 32 g/mol = 1.248 g
c) Equation of the reaction;
2NaNO3 -----> 2NaNO2 + O2
Number of moles of 128 g of oxygen = 128g/32 g/mol = 4 moles
2 moles of NaNO3 yields 1 mole of oxygen
x moles of NaNO3 yields 4 moles of oxygen
x = 8 moles of NaNo3
Mass of NaNO3 = 8 * 85 g/mol = 680 g of NaNo3
Answer:
0.0745 mole of hydrogen gas
Explanation:
Given parameters:
Number of H₂SO₄ = 0.0745 moles
Number of moles of Li = 1.5107 moles
Unknown:
Number of moles of H₂ produced = ?
Solution:
To solve this problem, we have to work from the known specie to the unknown one.
The known specie in this expression is the sulfuric acid, H₂SO₄. We can compare its number of moles with that of the unknown using a balanced chemical equation.
Balanced chemical equation:
2Li + H₂SO₄ → Li₂SO₄ + H₂
From the balanced equation;
Before proceeding, we need to obtain the limiting reagent. This is the reagent whose given proportion is in short supply. It determines the extent of the reaction.
2 mole of Li reacted with 1 mole of H₂SO₄
1.5107 mole of lithium will react with 
= 0.7554mole of H₂SO₄
But we were given 0.0745 moles,
This suggests that the limiting reagent is the sulfuric acid because it is in short supply;
since 1 mole of sulfuric acid produced 1 mole of hydrogen gas;
0.0745 mole of sulfuric acid will produce 0.0745 mole of hydrogen gas
The correct answer is alcohol. It is the common component in beer, wine and any liquor. Usually, alcohol is produced by fermentation of organic products containing glucose to produce alcohol, specifically ethanol, as the important product and the by-products water and carbon dioxide.
