Answer:
like i said put them all in numeral order and youll get them right
Explanation:
Answer:
The molarity of the HCl solution is 0.17M
Explanation:
When a titration occurs between an acid and a base it is called neutralization.
The formula to calculate the concentration of the acid is:
Ca*Va=Cb*Vb
where Ca and Cb are the concentrations of the acid and the base respectively and Va and Vb are the volumes of the acid and the base.
As HCl is an acid, solve the equation for Ca:

Replacing values:


Therefore the molarity of the HCl solution is 0.17M
Answer:
When excited electrons fall to lower energy levels, they can release energy in the form of light. metal ions in the salts used in the flame tests.
Answer:
Atom
Explanation:
Its the smallest unit into which matter can be divided without the release of electrically charged particles.
Given:
257J of heat
5500g of mercury
increase by 5.5
degrees Celsius
Required:
Specific heat of
mercury
Solution:
H
= mCpT
257J = (5500g of
mercury) Cp (5.5 degrees Celsius)
Cp = 8.5 x 10^-3
Joules per gram per degree Celsius
