According to the law of conservation of mass, in A2 + B2 = 2c, the chemical formula of C can be expressed as A.B_____ ? The first two 2 are subscripts, and the second 2 is the measurement number

According to the law of conservation of mass, in A2 + B2 = 2c, the chemical formula of C can be expressed as A.B_____ ? The first two 2 are subscripts, and the second 2 is the measurement number

AB
mass conservation
1*2A+1*2B=2C
A2B2=2C
2(AB)=2C
C=AB
In fact, we can also use the single substance substitution method
A2+B2=2C
For example, H2 + Cl2 = 2HCl
A2 H2
B2 Cl2
As long as it's a simple substance, it's also possible to get it by replacing the same quantity
