Answer:
When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation
Explanation:
Answerd the question : ion
Answer:
AB + CD → AC +BD
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Example:
The following reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
While,
A + B → AB
Synthesis reaction:
It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.
AB → A + B
Decomposition:
It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.
AB + C → AC + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
Answer:
145.97×10²³ atoms
Explanation:
Given data:
Number of moles of CO₂ = 8.08 mol
Number of atoms of CO₂ = ?
Solution:
1 mole of CO₂ contain 1 mole C atom.
8.08 mole contain 8.08× 1 = 8.08 mole of C atom.
1 mole of CO₂ contain 2 moles of O atom.
8.08mole contain 8.08×2 = 16.16 mole of O atom.
Total number of moles of atoms = 8.08 mole + 16.16 mole
Total number of moles of atoms = 24.24 mol
Number of atoms of CO₂:
1 mole of any substance contain 6.022×10²³ atoms.
24.24 mol ×6.022×10²³ atoms / 1 mol
145.97×10²³ atoms
Answer:
4
