What is the molarity of a solution prepared by mixing 12.5 g of fecl3 in enough water to make 300 ml of solution?

0.256 M

Explanation: Molarity (M)= (mass/molar mass)(1000/Volume in mL)

M= 12.5x1000/162.2x300=0.256 M

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? ?

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
