The double replacement reaction
<h3>Further explanation</h3>
Given
Reaction if Na₂S + HCl
Required
Type of reaction
Solution
The double replacement reaction occurs when there is a displacement of the cations and anions of the reactants involved in the reaction to form two new compounds.
The general formula for this reaction :
AB + CD ⇒ AD + CB
At the bottom of the reaction, it is shown the number of atoms of each compound in the reactants and products which indicates the application of <em>the law of conservation of mass</em>, that the number of atoms in the reactants will be the same as the number of atoms in the product, so the reaction is said to be in a balanced state.
Answer:
0.0000159
Explanation:
Divide 15.9 by 1000000, because 1 kilometer equals 1000000 millimeters.
Because of the surface tention.
Answer:
negative acceleration describes a decrease in velocity over time. Acceleration is an increase and zero acceleration is no change in velocity.
