Answer:
96 g of O
Explanation:
Mg(OH)₂ → Magnesium hydroxide
Molar mass → 24.3g/mol . 1 + 16g/mol . 2 + 1g/mol . 2 = 58.3 g/mol
We determine the moles of hydroxide → 175 g . 1mol/58.3g = 3 moles
Let's make some rule of three:
In 100 g of compound we have 54.87 g of O
In 58.3 g of compound we may have (58.3 . 54.87) / 100 = 32 g
So, 1 mol of hydroxide has 32 g of oxygen
3 moles of hyroxide may have (3 .32)/1 = 96 g of O

PLS Im only partly sure about a few but this is my answer.
Answer:
must be either a gas or liquid
Answer:
T=√250 or ≈15.81
Explanation:
by dividing both sides by .008, you eliminate .008 on the left side and get 2÷.008=250 on the right. to eliminate the ^2 on T, you need to square root both sides, so on the left it's √T^2=T, and on the right it's √250, or roughly 15.81.
