Answer:
Volume required = 0.327 L
Explanation:
Given data:
Volume in L = ?
Molarity of solution = 1.772 M
Mass of BaCl₂ = 123 g
Solution:
First of all we will calculate the number of moles of BaCl₂,
Number of moles = mass/molar mass
Number of moles = 123 g/ 208.23 g/mol
Number of moles = 0.58 mol
Now, given problem will solve by using molarity formula.
Molarity = number of moles / volume in L
1.772 M = 0.58 mol / Volume in L
Volume in L = 0.58 mol / 1.772 M
Volume in L = 0.327 L
Answer: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat.
Explanation: When a hydrogen-carbon-based fuel (like gasoline) burns, the exhaust includes water (hydrogen + oxygen) and carbon dioxide (carbon + oxygen).
Answer:
The atomic mass of an atom is the number of protons plus neutrons.
Fact: In case you get it confused with atomic number, atomic number is the number of protons in the atom.
Explanation: It could have been electrons plus neutrons since electrons equals protons but electrons aren't stable which is why it is protons and neutrons.
Answer:
This is like having enough energy to supply the world for centuries with just 1% of the sea's force? The amount of energy in it can supply energy therefore the one drop of tea is able to run her air conditioning for the rest of her life.
Explanation:
It would be potassium chloride or kcl
