Which of the following statements is an application of the law of conservation of mass for the reaction? 2H2 + O2 --> 2H2O

A.) 4 grams of hydrogen gas and 32 grams of oxygen gas react to form 36 grams of water

B.) 5 grams of hydrogen gas and 10 grams of oxygen gas react to form 5 grams of water

C.) 10 grams of hydrogen gas and 10 grams of oxygen gas react to form 10 grams of water

D.) 10 grams of hydrogen gas and 10 grams of oxygen gas react to form 20 grams of water

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

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.
