Write a BALANCED chemical equation for the acid base reaction between aqueous perchloric acid and aqueous calcium hydroxide.​

Chemistry
1 answer:
sergejj [24]3 years ago
5 0

Answer:

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

Explanation:

Formula for aqueous perchloric acid is; HClO_4 (aq)

Formula for aqueous calcium hydroxide is; Ca(OH)_2 (aq)

Thus chemical equation is;

HClO4 + Ca(OH)2 = Ca(ClO4)2 + H2O

We have to balance it and so we now have;

2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O

Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then
Bogdan [553]

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

I hope this helped :) If not i'm sorry!

How many grams of H, are needed to react with 2.75 g of N,?
Elena-2011 [213]

Answer:

0.6 grams of hydrogen are needed to react with 2.75 g of nitrogen.

Explanation:

When hydrogen and nitrogen react they form ammonia.

Chemical equation:

N₂ + 3H₂ → 2NH₃

Given mass of nitrogen = 2.75 g

Number of moles of nitrogen:

Number of moles = mass/ molar mass

Number of moles = 2.75 g / 28 g/mol

Number of moles = 0.098 mol

Now we will compare the moles of nitrogen with hydrogen from balance chemical equation:

                   N₂             :          H₂

                    1               :           3

                   0.098       :        3×0.098 = 0.3 mol

Mass of hydrogen:

Mass = number of moles × molar mass

Mass = 0.3 mol × 2 g/mol

Mass = 0.6 g
