Answer:
D
Explanation:
With there being more things (and technically more surface area) more organisms can hid in the little crevasses.

The atomic mass for phosphorus is 31. So the molar mass of P is 3.54/31=0.114 mol. And according to the reaction equation, the ratio of coefficient is equal to the mole number. So the theoretical mass of P2O5 is 8.094 g. The actual yield is 6.807 g.
Answer:
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
Explanation:
Assuming Pressure is constant.
where T1 and T2 are temperature in Kelvin
Substituting the give values we get-
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
Density = 7.90 g/cm³
volume = 1.00 cm³
Therefore:
mass = density * volume
mass = 7.90 * 1.00
mass = 7.90 g
