What is the [H ] of a solution of 0.001 M aqueous sulfuric acid (H2SO4) is H2SO4 ionizes in water according to the balanced chem

Ainat [17]

Answer: 0.002 M

Explanation:

The balanced chemical equation for ionization of $H_2SO_4$ in water is:

$H_2SO_4\rightarrow 2H^++SO_4^{2-}$

According to stoichiometry :

1 mole of $H_2SO_4$ ionizes to give =2 mole of $H^+$ ions

0.001 mole of $H_2SO_4$ ionizes to give = $\frac{2}{1}\times 0.001=0.002$ mole of $H^+$ ions

Thus $H^+$ of a solution of 0.001 M aqueous sulfuric acid is 0.002 M

erica [24]

Answer and Explanation:

$Greetings!$

$Let's~answer~your~question!$

$Partial ~pressure ~of ~gas ~can ~be ~directly~ calculated ~by ~multiplying ~the~ percentage\\ of~ pressure~ of~ gases~ to ~the ~total ~pressure.$

$\boxed{Pgas~ = ~P~total~ * \% ~P ~of ~gas}$

For % of N2 gas: 

 $100\% - (5\% + 12\%) = 83\% ~N2$ 

 $PN_2 ~= ~146~ atm~ *~ 0.83 ~ = 121.18 ~atm$ 

 $PO_2 ~= ~146~ atm~ *~ 0.12~ = 17.52 ~atm$ 

 $~PCO_2~ = ~146~ atm ~* 0.05 = 7.3 ~atm$
