Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
Answer:B
Explanation:
The early theory says that atom Is the smallest indivisible particle. Which was later proven to contain electron neutron and proton
The O Layer. I believe. Or the A horizon

Answer:
Yield = 66.7%
Explanation:
4P + 5O₂ → 2P₂O₅
P: 31 g/mol
O₂: 32 g/mol
P₂O₅: 142 g/mol
31 g P ____ 1 mol
2.80 g P __ x
x = 0.09 mol P
142 g P₂O₅ ____ 1 mol
3.89 g P₂O₅ ___ y
y = 0.03 mol P₂O₅
In a 100% yield, 4 mol of P produces 2 mol of P₂O₅. 0.09 of P should, therefore, produce 0.045 mol of P₂O₅.
Yield = (0.03 mol / 0.045 mol) x 100
Yield = 66.7%
