Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20
Answer:
5
Explanation:
all you do is the math expression
ClO(4)− is regarded as perchlorate ion and are produced commercially in most situations as salts via industries and in the laboratory.
<h3>What is P
erchlorate ion?</h3>
This ion is referred to as a monovalent inorganic anion and is obtained by deprotonation of perchloric acid. It is composed of chlorine and oxygen atoms in the ratio 1 to 4 respectively.
This has 32 valence electrons available in the Lewis structure and is used in the commercial production of solid rocket fuel.This ion has a molar mass of 99.451 g mol−1 and is used in different processes such as an oxidizer and to control static electricity during the process of food preservation in industries.
Therefore ClO₄− is also regarded as perchlorate ion and is the most appropriate choice.

Answer:

Explanation:
(a) Balanced equation
3ZnCO₃ + 2H₃PO₄ ⟶ Zn₃(PO₄)₂ + 3H₂O + 3CO₂
(b). Calculation
You want to convert moles of Zn₃(PO₄)₂ to moles of ZnCO₃
The molar ratio is 1 mol Zn₃(PO₄)₂:3 mol ZnCO₃

You need
to form 3.0 mol of Zn₃(PO₄)₂.
