Answer:
Explanation:
Here, we want to check if the equation of the reaction is balanced or not
Now, for a balanced equation of reaction, the number of atoms of the individual elements on both sides of the equation is equal
Now, let us check the atoms:
We have 1 Sr on both sides
We have 1 SO4 on both sides
We have 1 Mg on both sides
We have 2 OH on both sides
From what we can see, the equation of the reaction is balanced
Thus, the correct answer choice is B
V= c/λ = 3.00 x 108 m/s = 4.3 x 1020 s-1 6.9 x 10-13 m

If it is incomplete or complete combustion. Normally the problems question with tell you.
EX:
"In the presence of plenty of oxygen" is complete combustion
"Not enough oxygen present" is incomplete combustion
