The image represents the reaction between a certain number of molecules of H2 and O2. If the maximum amount of H2O is formed during the reaction, what is the leftover reactant?

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

if you're asking what comes out, it's steam.

the answer is c i took the test
