Which best describes the reducing agent in the reaction below? Cl2(aq) + 2Br–(aq) Right arrow. 2Cl–(aq) + Br2(aq)
Bromine (Br) loses an electron, so it is the reducing agent.
Bromine (Br) gains an electron, so it is the reducing agent.
Chlorine (Cl) loses an electron, so it is the reducing agent.
Chlorine (Cl) gains an electron, so it is the reducing agent.

do u know how to do science

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
