a) Hóa trị của Ca trong Ca(NO3)2 là II

b) Mgx(PO4)y => x = 3 ; y = 2 (vì hóa trị của Mg là II ; PO4 là III)

Alx(CO3)y => x = 2 ; y = 3 (vì hóa trị của Al là III ; CO3 là II)

a) Hợp chất có công thức: X2H6

Do M của hợp chất nặng gấp 15 lần so với H2

2X + 6 =15*2  =>X=12 X là Cacbon

b)%X=(12/30)*100%=40%

nhớ k nhá

6 tháng 11 2021

Gọi CTHH của hợp chất X là  R2H6 

Ta có : \(M_{R_2H_6}=M_{NO}=40\)

<=> MR.2 + MH.6 = 40

<=> MR.2 + 1.6 = 40

<=> MR = 12

=> R là Cacbon

b) CTHH Hợp chất X là C2H6

c) \(\%C=\frac{M_C}{M_{C_2H_6}}=\frac{12}{40}=30\%\)
