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
A. is a hypothesis because hypotheses are usually in the form of if-then statements.
Answer:
Explanation:
Its chemical energy to Chemical energy because carbon is a chemical in science sorry if its incorrect.
The equation for the reaction between Ca3N2 and Al2O3 wiil be;
Al2O3 + Ca3N2 = 2AIN +3CaO
Thus, the products of the reaction will be Aluminium Nitride and Burnt lime(Calcium oxide). A double displacement reaction, also known as a double replacement reaction or metathesis, is a reaction where two compounds react, and the positive ions and the anions switch places, forming two new compounds or products.
