In the reactants there is a curvy arrow, what does the direction of the arrow indicate?
a. because cations are sharp and anions are dull
b. because the anions and cations share electrons
c. because the cations give away an electron and the anions accept electrons

Option C.

Because the cations give away an electron and the anions accept electrons

Option (C) is the correct answer.

Explanation:

When a curvy arrow is placed on the reactants then it shows that an electron is being transferred from one atom to another.

And, it is known that when donation or transfer of an electron occurs from one atom to another then it results in the formation of an ionic bond and the compound formed is known as ionic compound.

For example, sodium when chemically combines with chlorine atom then one valence electron is donated by sodium atom to the chlorine atom. This forms the ionic compound NaCl.

Thus, we can conclude that in the reactants there is a curvy arrow,  the direction of the arrow indicate that the cations give away an electron and the anions accept electrons.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
