Answer: The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods
CH2O3
C=19.36\12 = 1.61
H=3.25\1.008 =3.22
O=77.39\16=4.83
then dived the moles with the smallest mole
C=1.61\1.61=1
H=3.22\1.61=2
O=4.83\1.61=3
E.F
CH2O3
Answer:
Explanation:
stoichiometry is used in cooking because it helps you determine the amount or proportion of compounds you will need in a chemical reaction. Stoichiometry is present in daily life, even in the cooking recipes we make at home. The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
I think it is a because it’s the closet so yeah
