Answer:
B, C ,E those are the three practice in the options you have
Physical because the substance isn’t chemically changing
The answer to the question is A
Answer:
Yes, yield.
Explanation:
N2(g) + 3 H2(g) → 2 NH3 (g) balanced equation
First, find limiting reactant:
Moles H2 = 1.83 g x 1 mole/2 g = 0.915 moles H2
Moles N2 = 9.84 g N2 x 1 mole/28 g = 0.351 moles N2
The mole ratio of H2: N2 is 3:1, so H2 is limiting (0.915 is less than 3 x 0.351)
Theoretical yield of NH3 = 0.915 mol H2 x 2 mol NH3/3 mol H2 = 0.61 moles NH3
<h3>
Answer:</h3>
4649.16 g
<h3>
Explanation:</h3>
We are given;
- The equation for the reaction
2C₄H₁₀ + 13O₂→ 8CO₂ + 10H₂O
We are required to determine the mass of water produced.
<h3>
Step: Determine the number of moles of C₄H₁₀</h3>
We know that, moles = Mass ÷ Molar mass
Molar mass of C₄H₁₀ is 58.14 g/mol
Therefore;
Moles of C₄H₁₀ = 3000 g ÷ 58.14 g/mol
= 51.5996
= 51.60 moles
<h3>Step 2: Determine the number of moles of water </h3>
- From the equation, 2 moles of C₄H₁₀ reacts to produce 10 moles of water
Therefore;
Moles of water = Moles of C₄H₁₀ × 10/2
= 51.60 moles × 5
= 258 moles
<h3>Step 3: Determine the mass of water produced </h3>
We know that; mass = moles × molar mass
Molar mass of water = 18.02 g/mol
Thus;
Mass of water = 258 moles × 18.02 g/mol
= 4649.16 g
Therefore, the mass of water produced will be 4649.16 g
