Answer:
2.0 × 10² g
Explanation:
Step 1: Write the balanced equation
2 NO₂ + 0.5 O₂ ⇒ N₂O₅
Step 2: Calculate the theoretical yield, in moles, of N₂O₅
The molar ratio of NO₂ to N₂O₅ is 2:1.
6.0 mol NO₂ × 1 mol N₂O₅/2 mol NO₂ = 3.0 mol N₂O₅
Step 3: Calculate the theoretical yield, in grams, of N₂O₅
The molar mass of N₂O₅ is 108.01 g/mol.
3.0 mol × 108.01 g/mol = 3.2 × 10² g
Step 4: Calculate the real yield, in grams, of N₂O₅
real yield = theoretical yield × percent yield
real yield = 3.2 × 10² g × 61.1% = 2.0 × 10² g
Answer:
Steam always has more thermal energy than ice.
Explanation:
Answer:
D. It contains a phosphate with higher phosphoryl transfer potential than ATP
Explanation:
1,3-Bisphosphoglycerate contains a phosphate group that has high phosphoryl transfer potential than ATP (they can transfer the phosphoryl group to ATP). Other high phosphoryl transfer potential groups include :Creatine kinase and phosphoenolpyruvate.
Protons and neutrons have about the same mass. Electrons are the smallest out of the three, in fact, protons weigh 1,836 times more than an electron.
Answer: Convection Currents
Explanation: The mantle rock is solid and denser because it is cooler. This means it will sink closer to lower mantle as warmer, lense dense rock/magma moves upwards.
