There’s no pic for me to awnser your question
Answer:
Because it is made up of many different parts that are combined, but can be physically separated from each other.
Answer:
A and B
Explanation:
This is because there was emission of gamma (Y) radiations in both the reactions.
72.0gAl× 2 mol Al × 2 mol alcl3 × (grams alcl3)
------------ ---------------- ------------------
(grams Al) 2 mol Al 2 mol alcl3
same goes for HCL, remember to use mole to mole ratio
Answer:
34.21g of ammonia
Explanation:
N2 + 3 H2 ------->2 NH3
First find the limiting reactant
Using hydrogen
10.62 g of H2× 1.0 mole of H2/2g H2 ×2.0 mol of NH3/3.0 mol of H2× 17.0 g of NH3/1.0 mol of NH3= 60.18g of NH3
Using nitrogen
28.17 g of N2× 1.0 mole of N2/28g N2 ×2.0 mol of NH3/1.0 mol of N2 × 17.0 g of NH3/1.0 mol of NH3= 17.1g of NH3
Hence nitrogen gas is the limiting reactant.
From the reaction equation:
28.0 g of nitrogen gas gives 34.0g of ammonia
28.17 g of nitrogen gas gives 28.17×34.0/28.0= 34.21g of ammonia
