Answer:
Propane gas plus oxygen gas produces water and carbon dioxide.
Explanation:
This is the initial chemical equation: C3H8 + O2 = CO2 + H2O
This is the balanced chemical equation: C3H8 + 5 O2 = 3 CO2 + 4 H2O
When mentos and diet coke are mixed, the diet soda explodes
Explanation:
Due to the fact that the mentos are dense, they sink to the bottom of the bottle which gives the diet coke its explosion.
I'm guessing you have to balance these.
I took a picture of my working out.
Answer to the first one = 2HCl+CaCO3=CaCl2+H20+CO2
So basically just add a big 2 in front of the first HCl
Answer to second one = 2Ni + O2 = 2NiO
So basically in this one just add a big 2 in front of both of the Ni
I am pretty sure it is nitrogen, oxygen, carbon and hydrogen.
<h2>Hello!</h2>
The answer is: cold, rising air.
<h2>
Why?</h2>
The high-pressure areas are at the poles due to the cold rising air. It's known that the cold air is more sense that the warm air because the warm gases molecules are more separated during the gas, is warm, which make it less dense than cold air.
Due to the form of our planet and the location of the poles, the cold air rises while the warm air down around the tropics and rise again to the poles (getting cold while it's getting closer to the poles).
High-pressure at poles is also caused because the solar radiation is higher at the equator than at the poles.
Have a nice day!
