Answer:
The reaction only takes place if the reactants are in contact, then the surface exposed is very important because as the exposed surface of the reactants increases, the reaction velocity also increases. If the lumps are not broken up, a big amount of baking soda would be only available to react after the surrounding soda has already reacted.
I just shot my shot at this little 52 ms far
I didn’t know water has calories
When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it's not able to hold all of the water vapor it once was. Air also can't hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.
I hope this helps you..
The kinetic energy of an object is given by

where m is the mass of the object and v its velocity.
For the car in the problem,

and

, so the kinetic energy of the car is

and as we can see, yes, the answer depends on the car's mass.
