Answer:
96g
Explanation:
Given parameters:
Number of moles of NaOH = 2.4moles
Unknown:
Mass of NaOH = ?
Solution:
The mass of a substance given the number of moles can be found using the expression below;
Mass of NaOH = Number of moles x molar mass;
Molar mass of NaOH = 23 + 16 + 1 = 40g/mol
Now input the parameters and solve;
Mass of NaOH = 2.4 x 40 = 96g
Explanation:
To balance this chemical equation-

Answer:
A solution is a heterogeneous mixture
Explanation:
This statement that a solution is a heterogeneous mixture is completely and totally wrong.
A solution is a homogeneous mixture.
Homogeneous mixtures have their constituents existing in just one phase.
- It is a homogeneous mixture of solutes and solvents.
- In a solution, the solutes particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- Solutes are usually present in a small amount than the solvent.
- The solvent acts as the dispersing medium which allows the solute to go into the solution.
- The solute can be solid, liquid or gas.
Answer:
This is True
Explanation:
A fossil is any remains or trace of an ancient organism. Fossils include body fossils, left behind when the soft parts have decayed away, as well as trace fossils
