Вычислите объём водорода (н. образовавшегося при взаимодействии 14, 6 г цинка с раствором соляной кислоты.

Дано:
m(Zn) =14г
HCl
V(H2) = 22,4
V(H2)-?


14г x, л
Zn + 2HCl=ZnCl2 + H2
65г/моль¯¯¯¯¯¯¯¯¯¯ 22,4 л
М(Zn) =65г/моль
V(H2)=m(Zn)*V(H2)/V(H2) *M(Zn)
V(H2)=14г*22,4л/x*65г/моль=4,8л

1. C2H6 + Br2 = C2H5Br + HBr
C2H5Br + NaOH = C2H5OH + NaBr
C2H5OH + CH3COOH ---(H2SO4)---> CH3COOC2H5 + H2O
CH3COOC2H5 + NaOH = CH3COONa + C2H5OH
CH3COONa + NaOH + t (сплав) = CH4 + Na2CO3  CH4 + t = C2H2
C2H2 + HCl = CH2=CH-Cl    nCH2=CH-Cl = [-CH2-CH(Cl)-]n

2. CH3COOCH3 ---(NaOH/H2O)---> CH3COONa + CH3OH
CH3OH + O2 ---(V2O5/t)---> HCOH + H2O
HCOH + [Ag(NH3)2]OH = Ag + HCOOH + H2O + 2NH3
HCOH ---(H2/Ni)---> CH3OH
CH3OH + C2H5COOH ---(H2SO4)---> C2H5COOCH3 + H2O
C2H5COOCH3 + NaOH (водн) = C2H5COONa + CH3OH
C2H5COONa + NaOH + t (сплав) = C2H6 + Na2CO3

3. C3H7OH ---(Cu/t)---> C2H5CHO + H2
C2H5CHO + Cu(OH)2 = C2H5COOH + Cu2O
C2H5COOH + C2H5OH ---(H2SO4)---> C2H5COOC2H5
C2H5COOC2H5 + NaOH (водн) = C2H5COONa + C2H5OH

My dream room. Wow, let's start with the interior I would like my room to have delicate pastel ocher wallpapers, on which I would hang posters of my favorite bands. My room must have a balcony with a table and two chairs. It will be decorated with different flowers and in the morning I will have a cup of coffee there. There will be a large round bed in my room, there will be a work table on the side, a dressing table next to it, a small table. Opposite the tables will be a wardrobe, vast and full of different and interesting outfits. There will be many plants in my room, and I will stretch a bright yellow garland across the ceiling. This is the room of my dreams
