The mesosphere is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the mesopause. In the mesosphere, temperature decreases as the altitude increases. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth[citation needed] with temperatures below −143 °C (−225 °F; 130 K). T

A engineer measures the peak power output is 0.3227MW what is the peak power output in kilowatts ?

Lana71 [14]

<h3>Answer:</h3>

322.7 kW

<h3>Explanation:</h3>

Power refers to the rate at which work is done.
Therefore; Power = Work done ÷ time
It is measured in joules per seconds or Watts

In this case, we are required to convert 0.3227 MW to kilowatts

We need to know that;

10^6 watts = 1 Megawatts(MW)
10^3 Watts = 1 kilowatts (kW)

Therefore;

10^3 kW = 1 MW

Therefore, the suitable conversion factor is 10^3kW/MW

Hence;

0.3227 MW is equivalent to;

= 0.3227 MW × 10^3kW/MW

= 322.7 kW

Thus, the peak power output is 322.7 kW

If you start with 0.020 g of Mg, how many moles of H2 will you make if the reaction is complete?

irina [24]

If one starts with 0.020 g of Mg, 0.0008 moles of H2 would be made if the reaction is complete.

Going by the balanced equation of reaction in the image, 1 mole of Mg will produce 1 mole of H2 in a complete reaction.

If 0.020 g of Mg is started with:

mole of Mg = mass/molar mass

= 0.020/24.3

= 0.0008 moles

Since the mole of Mg to H2 is 1:1, thus, 0.0008 moles of H2 will also be made from the reaction.
