Answer: Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)
Balanced equation:
<span>2 Na + 2 H₂O = 2 NaOH + H₂</span>
mole ratio :
2 moles Na ----------- 2 moles H₂O
12 moles Na --------- ? moles H₂O
moles H₂O = 12 x 2 / 2
moles H₂O = 24 / 2
= 12 moles of H₂O
hope this helps!
4) the equation for Boyle’s law is P1V1 = P2V2 meaning that pressure is inversely proportional to the volume (when one increases the other decreases)
5) We know that pressure is inversely proportional to the volume when temperature is constant. So if volume was decreased the pressure would increase. In this situation the gas was shifted to a tank with less volume from 5L to 1L, so the pressure will be increased by a factor of 5x.
6) (325 x 1)/0.25 = 1300kPa is the pressure inside of the piston chamber
Answer:
Magnesium Ion
Explanation:
This is a Magnesium ion. There are 12 protons from the magnesium atom. There are 10 electrons because 12-2=10. There are 12 neutrons because 24-12=12
