Explanation:
sodium (Na +)
Carbonate ion (CO₃²⁻)
Ionic compounds are formed between ions (Anions and Cations).
For a neutral compound to be formed, the charges of the ions must cancel each other out.
Sodium ion has a charge of +1
Carbonate ion has a charge of -2
The only way to make sure both ions have similar charges is to multiply each ion by the coefficient of the other.
Thus we have;
Sodium ion = +1 * 2 = +2
Carbonate ion = -2 * 1 = -2
From this, the chemical formular of the product formed between both ions must contain 2 sodium ions and one carbonate ion.
This is given by;
Na₂CO3
Answer:
Hi there!
Your answer is
Mass: 12
&
Electrons:5
Explanation:
The electrons in a neutral atom is the same as the # of Protons!
The Halogen that is most likely easy to be oxidised would be the Iodine. In addition, the property that makes the Iodine ideal for oxidation is due to the fact that its d-orbital contains more electrons compared to other halogens such as fluorine where oxidation would tend to be difficult to occur on the element.
I believe that the ice cube, being that it still has almost all of its properties, would still have a mass of 25 g after melting
