Answer:
0.75moles of H₄SiO₄
Explanation:
Given parameters:
Number of moles of H₂O = 1.5moles
Unknown:
Number of moles of H₄SiO₄ = ?
Solution:
To solve this problem, we need to write the reaction equation first;
SiO₂ + 2H₂O → H₄SiO₄
From the balanced reaction equation:
2 moles of water will produce 1 mole of H₄SiO₄
So 1.5 moles of water will produce 
= 0.75moles of H₄SiO₄
GPE is the gravitational Potential Energy which is given by mgh.
mg is the gravitational force(a force) and h is the height of the object(or distance of the object from earth's surface)
SO GPE = mg (force) x h (distance)
Answer:
The answer is D, I would type it out but it is to long and I'm kind of lazy, but anyways! Your answer is D

Probably true because chemicals do control weed and it hurts the environment.
