Which set of coefficients would balance the following chemical equation?
h3po4 + rboh → h2o + rb3po4
question 3 options:
2h3po4 + rboh → 3h2o + rb3po4
h3po4 + rboh → h2o + rb3po4
h3po4 + rboh → 2h2o + rb3po4
h3po4 + 3rboh → 3h2o + rb3po4

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.
