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
Answer:
During a phase change no chemical bonds are broken. Atoms are not rearranged because a phase change is a physical change rather then a chemical change. However, intermolecular forces are almost entirely removed from the liquid since the intermolecular forces are what cause the liquid to be a liquid.
Explanation:the nature of the intermolecular forces (IMF) will not change when the state changes from solid to liquid, however, the number of IMF changes.
