Just count the electrons and search which atom it is.
Answer:
Number of moles = mass/molar mass
Explanation:
Given data:
mass of Al = 11 g
Moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of aluminium is 27 g/mol
Now we will put the values in formula.
Number of moles = 11 g/ 27 g/mol
Number of moles = 0.41
The number of moles in 11 g Al are 0.41 mol.
I think your answer would be that it increased
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.
