Answer:
This is a substance that has definite composition
Explanation:
chemicals are substances that can not be broken down any further by physical process.it is a form of matter having a constant chemical characteristics and properties
Answer:
The Law of Definite Proportions ensures that chemical compounds are always created using the same proportions, regardless of the amount of the compound which is being made
Volume (in mL) is 1.61 ml would you need to dilute 35.0 mL of a 1.30 M solution of KBr to make a 0.0600 M solution of KBr
Dilute is to make a liquid weaker by mixing in something else
The volume or concentration of the concentrated or dilute solution can be determined by using the equation:
M₁ V₁ = M₂ V₂
Here given data is
M₁ = 1.30 M
M₂ = 0.0600 M
V₂ = 35.0 mL
V₁ =?
Then substitute this value
M₁ V₁ = M₂ V₂
1.30 M×V₁ = 0.0600 M×35.0 mL
V₁ = 1.61 ml

Answer:
repelled
Explanation:
like charges repel one another
Answer:
Solubility : The mass of a salt in grams that will dissolve in 100 mL of water
Saturated solution : A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved
Solubility product constant :The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation
Common ion effect : A decrease in the solubility of an ionic compound as a result of the addition of a common ion
Molar solubility : The maximum number of moles of a salt that will dissolve in 1 L of solution
Explanation:
Solubility is expressed usually as the mass of solute per 100 grams or 100 ml of solvent.
Molar solubility of a solid is expressed as the concentration of the dissolved solid in a saturated solution.
Solubility product constant is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The common-ion effect is the decrease in solubility of a sparingly soluble salt by the addition to the solution of a soluble compound with an ion in common with the precipitate.
Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.
