What are " of the following"?
Answer:I think it could be A or B but I would choose A.
Explanation:
The molar mass of PH3 is 34 g/mol, therefore the moles
is:
moles PH3 = 225 g / (34 g/mol)
moles PH3 = 6.62 mol
The balanced equation is:
4PH3(g) + 8O2(g) → P4O10(g) + 6H2O
We see that 4 mol of PH3 is required for every mol of
P4O10, therefore the number of moles of P4O10 is:
moles P4O10 = 6.62 mol * (1/4)
moles P4O10 = 1.65 mol
The molar mass of P4O10 is 283.89 g/mol, so the mass is:
mass P4O10 = 1.65 mol * 283.89 g/mol
mass P4O10 = 469.67 grams ~ 470 grams
Answer: Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. ... O=O. double bonds are much stronger than S=S double bonds.
