A chemical bond that is formed when two atoms share electrons is called a covalent bond :)
Greetings!
I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.
Hope this helps you!

4 covalent ---because bromine is a non-metal and each atom must share electrons in order to satisfy the octet rule. In a covalent bond, two atoms share a pair of electrons. IOnic bonds form as a result of the transfer of electrons from one atom to another.
Answer:
t = 50 s
Explanation:
P = W/t
Solving for t,
t = W/P = (3430000 J)/(68600 Watts)
= 50 s
Note: 1 Watt = 1 J/s
Answer: Hence, 2 moles of NaOH would neutralize 1 mole of 
Explanation:

One mole of hydrochloric acid neutralizes one mole of sodium hydroxide to give one mole of sodium chloride and one mole of water
When sulfuric acid is used in the place of HCl , 1 mole of sulfuric acid will neutralizes the 2 mole of sodium hydroxide and gives one mole of sodium sulfate and 2 moles of water. As we can see from the reaction:

Hence, 2 moles of NaOH would neutralize 1 mole of
