Calculate the number of atoms of O contained in 16.0 pounds of O
16.0 lbs = 7,257 g of O2
Oxygen exists in the gas form as 02
7,257g O2 * 1 mol O2/ 32 g * 2 mol O / 1 mol O2 * 6.022x10^23
atoms/mol
= 2.73E26 atoms of O
What is the general form of a synthesis reaction
What information does a solubility table give
it tells which compounds will dissolve in water
What is the mass percent composition of an element in a molecule
Percentage composition= (mass of the element/mass of the
molecule)*100
The fraction of the molecule's mass that comes from the
element's mass
What would be the percent yield of the reaction be if the theoretical yield is 11.22 g but the actual yield was 8.67 g
In this case the yield is 77,27 %.
Which the following is a necessary product of a combustion reaction
How should the combustion reaction C5H8 O2 CO2 H2O be balanced
Answer this question…
C5H8 + 7O2 5CO2 + 4H2O
In the reaction 2Li(s)+2H2O(l) ➝ 2LiOH(aq)+H2(g), which compound is in the gaseous state
