True
3. Fission reactions can be controlled; thus, they are used to create energy and electricity. But fusion reactions are uncontrollable and require too much energy for economical use.
True

Answer: there is more atoms of each element on the right.
Explanation:
On the left of the arrow you have:
Si-1
F-4
H-4
O-2
On the right of the arrow you have:
Si-3
F-6
H-8
O-4
A balanced equation always has the same amount of each element on the left of the arrow (the reactants) as the right (the products). This isn’t balanced because you have a lot more of each element on the right.
From the periodic table:
mass of carbon = 12 grams/mole
mass of hydrogen = 1 gram/mole
mass of oxygen = 16 grams/mole
The given compound C₆H₁₂O₆ has 6 moles of carbon, 12 moles of hydrogen and 6 moles of oxygen.
Therefore, the molar mass of the given compound will be calculated as follows:
molar mass = 6(12) + 12(1) + 6(16) = 180 grams/mole
Answer:
D all above yes I think it's all above
