Hello, I see that you are studying Jan Baptist van Helmont, founder of pneumatic chemistry. I assume that you are studying gases and how plants work.
van Helmont, in his experiment studied the theory of how "plants grow while eating soil." Weird right? He put a willow tree in soil, but before doing that, weighted the soil. After 5 years of seeing the same mass of soil, he concluded that plants grew by drinking water.
So the answer would be:
- Plant mass is related to H₂O
- Conclusions partially correct.
It depends on which type of power
<span>the ability to do something or act in a particular way, especially as a faculty or quality. is probally the one your looking for
</span>
You would need to isolate the variable by dividing each side by factors that don't contain the variable. So, the answer would be
x = 2.2
Answer:
0.425 moles of P₂O₅.
Explanation:
As per given balanced equation, four moles of phosphorus reacts with five moles of oxygen to give two moles of P₂O₅.
As given that the initial moles of phosphorus taken = 0.97 moles
moles of phosphorus left after reaction = 0.12 moles
moles of phosphorus reacted = 0.97-0.12 = 0.85 moles
When four moles of P reacts they give two moles of P₂O₅.
when one mole of P will react to give =
0.85 moles of P will react to give = P₂O₅
