Answer:

Joined together to form compounds or rearranged.

Explanation:

Dalton's Theories

-atoms from two or more different elements join together to form compounds in chemical reactions.

-chemical reactions rearrange atoms, but in specific compounds the atoms of different elements always combine in the same way.

It's because the Law of Conservation of Mass WILL NOT be followed if, from SO2 and water, sulfuric acid is formed. Making a balanced chemical reaction is not possible, no matter what you do. To obtain or make sulfuric acid, SO2 still needs to be oxidized further to SO3.

What volume of O2(
irakobra [83]
Answer is: volume of oxygen is 4.63 liters.
Balanced chemical reaction: 2C + O₂ → 2CO.
m(C) = 4.50 g.
n(C) = m(C) ÷ M(C).
n(C) = 4.50 g ÷ 12 g/mol.
n(C) = 0.375 mol.
From chemical reaction: n(C) : n(O₂) = 2 : 1.
n(O₂) = 0.1875 mol.
T = 48°C = 321.15 K.
p = 810 mmHg ÷ 760 mmHg/atm= 1.066 atm.
<span>R = 0.08206 L·atm/mol·K.
Ideal gas law: p·V = n·R·T.</span>
V(O₂) = n·R·T / p.<span>
V(O₂) = 0.1875 mol · 0.08206 L·atm/mol·K · 321.15 K / 1.066 atm.</span><span>
V(O₂<span>) = 4.63 L.</span></span>

What is the h+ concentration for an aqueous solution with poh = 3.35 at 25 ∘c? express your answer to two significant figures an
RSB [31]
POH value was calculated by the negative logarithm of hydroxide ion concentration.
To know the hydrogen ion concentration, we need to know the pH value, that can be found out if pOH is known 
pH + pOH = 14
pH = 14 - pOH 
pH = 10.65
once the pH is known we have to find the antilog. 
[H⁺] = antilog (-pH)
antilog can be found by 
[H⁺] = 10^(-10.65)
[H⁺] = 2.2 x 10⁻¹¹ M
