Oh yeah sweetie I’m gonna stop bye sis
<span>2 H</span>₂<span> + O</span>₂<span> = 2 H</span>₂<span>O
4 g H</span>₂ ------------ 32 g O₂----------- 36 g H₂O
<span> 8 g H</span>₂ ------------ 64 g O₂------------ ? g H₂O
<span>
Mass of H</span>₂O :
<span>
64 * 36 / 32 =
2304 / 32 = 72 g of H</span>₂O

The correct formula : BeSO₄
<h3>Further explanation</h3>
Chemical formula shows the composition number of the constituent atoms
Polyatomic ion consists of 2 or more ions
The equal charge of the two ions will cancel each other out, while the different charges of the two ions will be crossed each other
Be²⁺ (monatomic ion) has a positive charge of +2, while SO₄²⁻ (polyatomic ion) has a negative -2 charge, so that the two charges with the same magnitude but with different charges cancel each other out so that the compound form is BeSO4

Answer : The number of moles of added must be, 0.37 mol
Explanation :
The given chemical reaction is:
Initial mol. 2.99 x 0 0
At eqm. (2.99-1.30) (x-1.30) 1.30 1.30
= 1.69
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
x = 1.67 mol
The moles of added = (x-1.30) = (1.67-1.30) = 0.37 mol
