Given the equation: ch4 + br2 → ch3br + hbr which type of reaction does this equation represent

Answer : The given equation represents "Substitution reaction" of alkanes

Explanation :

The given reaction is,

To find out the type of reaction, we need to look at the reactants and products involved in the reaction

CH₄ is an alkane known as methane and Br₂ is bromine which belongs to halogen family.

During the reaction , we can see that one of the H atoms of methane is substituted by Br to form a product CH₃Br.

Therefore this is a "substitution reaction of alkanes" Since a hydrogen atom gets replaced by a halogen atom, it is also termed as "halogenation of alkanes"

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 !

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
