Answer:
This is not a balanced equation
Explanation:
Let's make it a balanced equation.
2 NH3 + H2So4 = (NH4)2So4
Glad I could help!!
The excess reactant is Aluminum.
<u>Explanation:</u>
We have to write the balanced equation as,
4 Al+ 3 O₂ → 2 Al₂O₃
According to the molar ratio 4: 3, from the given balanced equation, we can say that 4 atoms of Al reacted with 3 molecules of oxygen.
Given that 10 atoms of aluminum reacts with 6 molecules of oxygen, as per the ratio only 8 atoms of Aluminum is required to react with 6 molecules of oxygen, so excess reactant is Aluminum.
Answer:
Density, 
Explanation:
It is given that the density of liquid mercury is 13.6 g/mL. We need to convert the density into lb/in³.
We know that,
2.205 lbs= 1 kg
1 g = 0.0022 lb
1 mL = 0.0610 in³
So, the density of liquid mercury is 
.
