Answer:
hmmmm
Explanation: Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer!
Answer: A
Explanation:
Plants take in sunlight, water, carbon dioxide. The produce sugar (glucose) and other things. It could not be deforestation. It can't be evaporation, that is from the water cycle. It cant be C due to it talking about precipitation, which is also from the water cycle. Therefore, it can only be A
PV
= nRT
We
are solving for pressure. We are given the volume, which is 0.100 L (equivalent
to 100 mL). The temperature is 273.15 K (equivalent to 0 Celsius). All we need
to do is convert the grams to moles before we can solve for pressure.
N₂
has a molecular mass of 28.02. This means that 510 g N₂ * (1 mole N₂/28.02 g
N₂) = 18.2 moles N₂
PV
= nRT
P
= nRT/V
R
is the gas constant. R = 0.08206 atm*L/(K*mol)
P
= (18.2 mol)*(0.08206 atm*L/(K*mol))*(273.15 K) / (0.100 L)
<span>P
= 4.08 *10^3 atm</span>

<span>The pressure is 4.08*10^3 atm.</span>
Well usually a tornado forms when hot air and cold air come together and in the south, but since the weather is cold and they live by mountains a tornado would not happen.
A hurricane happens by the ocean.
I believe the answer would be a rainstorm. <span />
