They have to form a chemical bond in order to brake them down first
One mole of hydrogen peroxide contains 6.02 x 10^23 molecules of hydrogen peroxide. And each molecule contains 4 atoms, so the answer is 4 x 6.02 x 10^23.
2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar
5bases: ammonia, baking soda, cough medicine, liquid soaps
3. Acids are very common in some of the foods we eat.
Bases have properties that mostly contrast with those acids
4. Acid+Base=H2O+Salt
HCI+NaOH=H2O+NaCI
Explanation:
2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)
4. Salt means any ionic compound formed from an acid/base reaction
Hope this helped
Calcium fluoride.
Ca is metal, F is non-metal, so they form ionic bond.
Ca as metal can form only positive ion. Ca in the second group, so the charge of Ca ion is 2+. Ca²⁺
F is in the 17th group, so it has 7 electrons on the last level. It is non-metal, non-metal, so it has negative charge -(8-7)=-1. "8" because on the last level cannot be more than 8 electrons. F-ion is F¹⁻.
Ca²⁺ F¹⁻
Number of positive charges should be equal to number of negative charges,
Formula of calcium fluoride
CaF2.
2 atoms Fluorine bond with Calcium.
