When fireworks go off, they produce smoke, which is evidence of a new substance being created.
Answer:
If 13.4 grams of nitrogen gas reacts we'll produce 16.3 grams of ammonia
Explanation:
Step 1: Data given
Mass of nitrogen gas (N2) = 13.4 grams
Molar mass of N2 = 28 g/mol
Molar mass of NH3 = 17.03 g/mol
Step 2: The balanced equation
N2 + 3H2 → 2NH3
Step 3: Calculate moles of N2
Moles N2 = Mass N2 / molar mass N2
Moles N2 = 13.4 grams / 28.00 g/mol
Moles N2 = 0.479 moles
Step 4: Calculate moles of NH3
For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3
For 0.479 moles N2 we'll produce 2*0.479 = 0.958 moles
Step 5: Calculate mass of NH3
Mass of NH3 = moles NH3 * molar mass NH3
Mass NH3 = 0.958 moles * 17.03 g/mol
Mass NH3 = 16.3 grams
If 13.4 grams of nitrogen gas reacts we'll produce 16.3 grams of ammonia
Answer:
<em>21.14 K</em>
Explanation:
<em>We know the Ideal Gas Equation is :-</em>
<em>PV = nRT</em>
<em>=> T = PV/nR</em>
<em>=> T = 6.5 x 20 / 7.5 x 0.082</em>
<em>=> T = 130 / 6.15</em>
<em>=> T = 21.14 K</em>
I would say D. Because if you displace too much water it would would either go to fast or not move at all... that's just my thought
