The compound NaOH(s) dissolves in water to yield

A) hydroxide ions as the only negative ions
B) hydroxide ions as the only positive ions
C) hydronium ions as the only negative ions
D) hydronium ions as the only positive ions

answer; i believe that the correct answer is (a) potassium(k)

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.

he would use the colour black
