This produces: 2 HBr
Yes it is.
2Br is two separate bromine atoms. Br2 is a bromine molecule, consisting of two bromine atoms bonded together.
H2 O2 Cl2 Br2 N2 I2 F2
Br2 + Zn ----> ZnBr2
They are diatomic molecules. They are hydrogen (H2), nitrogen (N2), oxygen (O2), chlorine (Cl2), bromine (Br2), iodine (I2), astatine (As2), and fluorine (F2).
Yes it is.
H2+Br2 2HBr
H2+Br2--->2HBr
You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.
Bromine is diatomic, so 2 atoms make up Bromine as a reactant. Mg + Br2 ----> MgBr2
2Br is two separate bromine atoms. Br2 is a bromine molecule, consisting of two bromine atoms bonded together.
H2 O2 Cl2 Br2 N2 I2 F2
Br2 + Zn ----> ZnBr2
Br2 + 2H2O + SO2 = H2SO4 + 2HBr
Br2 + 2NaI -> 2NaBr + I2
H2, N2, O2, F2, Cl2, Br2, and I2
An acid plus a metal produces a salt of the acid plus Hydrogen gas. 2HCl + 2Na ---> 2NaCl + H2
