A tissue contains tightly packed cells that form the covering of internal organs. Some of these tissues produce mucus or contain tiny hairs called cilia. Which tissue type is being described

The four types of tissues in the body are nervous muscle epithelial and connective tissue

Nervous tissue contains two types of cells neurones and neuroglia which makes up the central nervous system and peripheral nervous system.

Muscle tissue allows muscles to contract and pull on bones to move.

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 !

can you list the answers so i can answer
