in which chemical reaction is the number of atoms in the reactants the same as the number of atoms in the products?
a. Zn+2HCI->H2+ZnCI2
b. CH4+O2->CO2+2H2O
c. CO2+CH2OH+O2
d. Li2CO3->LiO+CO2
1.Zn + 2HCl → H2 + ZnCl2
2. The total number of atoms does not change, so mass is conserved in the reaction
3. 215 amu
4.76 amu
I took the quick check and these were the answers
UwU is 100% right
hopefully you get a 100%
1.Zn + 2HCl → H2 + ZnCl2
2. The total number of atoms does not change, so mass is conserved in the reaction

4.76 amu
Trust me these are right and good luck love's ✌️
UWU IS RIGHT I GOT A 100%
UWU is right i got 100
uwu is correct!! thank you <333
uwu is correct
Thank you so much !!!!
