Question

Ce cantitate de H reactioneaza cuș 710 g Cl pentru a obtine HCl

Answer 1

$n=2~moli~CO_{2} \\ m CO_{2}=? \\ M _{CO _{2} }= A_{C} +2* A_{O} = \\ =12+2*16 \\ =12+32 \\ =\boxed{44} \\ n= \frac{m}{M} \\ 2~moli~CO _{2} = \frac{m}{44~g/mol} \\ m=2~moli~CO _{2} *44~g/mol \\ m=88~g \\ P.S.=steluta~ inseamna~ inmultit.$
