We can solve the equation and show the solution below:
Oxygen atomic number is 16.
Phosphorus atomic number is 32.
We have the molecular weight:
Molecular weight = (31*4) + (16*10)
Molecular weight = 284 grams/mol
Solving for the grams:
0.4 mole (for P4) * (1 mol P4O10/1 mol P4) * (284 grams P4O10/1 mole P4O10)
Total grams = 113.6
The answer is 113.6 grams.
Answer:
C. Rate = k[H2]^2[O2]
Explanation:
Rate law only cares about REACTANTS. Since, rate law can only be determined experimentally, I am assuming the given reaction mechanism is elementary reaction from which we can write the rate law.
Only H2 and O2 are part of rate law since they are reactants and also the coefficient in front of H2 goes as exponent on rate law to indicate the order of H2 in the reaction.
Rate= k [H2]^2 [O2]
<span>Answer:
The dilution formula is V1M1 = V2M2.
We need 3 of the values to calculate the 4th.
We have the original volume (2 mL of copper ion solution) and the final volume (20 mL), but we don't have the concentration of either the original or the final copper solution,
All we can say is the resulting solution is 10 times as dilute as the original was-
V1M1 = V2M2
2Ă—0.200 = 20Ă—M2, so M2 = 0.400/20 = 0.020M</span>
