Here's what I get
Explanation:
SiO₂ + 4HF ⟶ SiF₄ + 2H₂O
The molar ratios are the same as the coefficients in the balanced equation.
Some of the molar ratios are
SiO₂:HF = 1:4
SiO₂:SiF₄ = 1:1
SiO₂:H₂O = 1:2
HF:SiF₄ = 4:1
HF:H₂O = 4:2
SiF₄:H₂O = 1:2
Answer:
gains 2 electrons. In order for the new ionic compound to form a a neutral compound, the oxygens must gain 6 electrons
Answer:
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
