Determine from the balanced chemical reaction if the derived mole ratio is correct or incorrect.
4Zn + 10HNO3 + 4Zn(NO3)2 + N2O + 5H20
4 moles Zn(NO3)2
2 mole HNO3
3)2)
correct
incorrect

Correct

Explanation:

Ive done this one before

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

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.
