The equation for the complete combustion of one mole of an alkane can be represented by alkane + ZO2 → XCO2 + YH2O
Complete combustion of one mole of the alkane produces 308 g of carbon dioxide and 144 g of water.
X, Y and Z are the numbers used to balance the equation.
Calculate the values of X, Y and Z.
[Mr of CO2 = 44, Mr of H2O = 18]

im not exactly sure but i think its b!

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
