mass

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

For example in the balanced equation :

Thus in the reactants, there are 4 atoms of hydrogen and 2 atoms of oxygen.Thus there will be 4 atoms of hydrogen, and 2 atoms of oxygen in the product as well.

Thus there will be equal mass on both sides of the balanced equation.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
