Answer:
c and o
Explanation:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.
- To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
- This leads the bond formation.
- Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons
You can use the formula M1 x V1 = M2 x V2 where M1 is the molarity of the first substance and V1 is the volume of the substance. M2 is the molarity of the 2nd substance and V2 is the volume of the substance
if substance 1 is HCl and 2 is KOH we can set up the following equation
x moles / liter (unknown) x .02 liters = .5 moles/ liter x .032 liters
x moles / liter x .02 liters = .016 moles
x moles / liter = .016/.02 liters
x moles / liter = .8 moles/ liter
You have . 8M HCL
Hydrogen Ions exist in acid solutions.
The answer to your question is letter A! Hope that helps
KOH -------> K+ OH-
Ba(OH)2 ------> Ba+2. 2OH-
