4 0

Answer:

A. Distance = 18 m

    time = 2 hr

    speed = 9 m/hr

Explanation:

Speed is the same thing as velocity.

Velocity = distance/time

18m/2hr = 9m/hr

For choice B, the numbers are right, but the units are mixed (minutes were changed to hours)

kondor19780726 [428]

Answer:

29.41% of Calcium and 47.04% of Oxygen

Explanation:

The percent composition of an atom in a molecule is defined as 100 times the ratio between the mass of the atom and the mass of the molecule.

The mass of the molecule of the problem (Ore) is 46.28g. That means the percent composition of Calcium is:

13.61g / 46.28g * 100 = 29.41% of Calcium

And percent composition of Oxygen is:

21.77g / 46.28g * 100 = 47.04% of Oxygen
