Answer:
Ag is the oxidizing agent
Explanation:
oxidizing agent in the following equation?
Al (s) + 3 Ag+ (aq) = Al+3 (aq) + 3 Ag (s)
Left side
Al = 1
Ag = 3
Right Side
Al = 1
Ag = 3
So it's balanced already good.
Define
oxidizing agent = An oxidizing agent is the substance that gains electrons and is reduced in a chemical reaction.
Al is the reducing agent.
Ag is the oxidizing agent
Answer:
The answer to your question is 80%
Explanation:
Data
mass percent of SO₄⁻²
molecule MgSO₄
Process
1.- Calculate the molecular mass of magnesium nitrate
molecular mass = (1 x 24) + (1 x 32) + (4 x 16)
= 24 + 32 + 64
= 120 g
2.- Calculate the molecular mass of sulfate ion
molecular mass = (1 x 32) + (4 x 16)
= 32 + 64
= 96
3.- Write a proportion to solve this problem
120 g of MgSO₄ ---------------- 100 %
96 g of SO₄⁻² --------------- x
x = (96 x 100) / 120
x = 80 %
Answer:
I'm pretty sure it's A. BRUSH
Explanation:
If I'm wrong let ne know please
LiClO3 has mole of mass of 90 g/mol
So 38.7 g means 0.43 mol
Since in this reaction, LiClO3 : O2 = 2:3, then it will produce 0.43*3/2 = 0.645 mol O2
So it is equivalent to 0.645 * 32 = 20.64 g O2
