When the equation below is balanced using the smallest whole number coefficients, what is the sum of all the coefficients?
If a molecule would have no coefficient, it is counted as 1.
C2H2(g) + O2(g) – CO2(g) +
H20(1)
a 16
b 8
C 4
d 12

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
