Answer:
D
Explanation:
Someone's perception can be all of these things. the way one person sees something is different than the way someone standing right beside them sees it.
Answer: Option (e) is the correct answer.
Explanation:
A compound that will dissociate in water or an aqueous solution to give hydrogen ions(
) is known as an acidic substance.
When RbH is dissolved in aqueous solution then it dissociates as follows.
.
is non-polar in nature. So, it will not dissociate into ions when dissolved in an aqueous solution.
will also remain neutral and does not dissociate into ions.
when dissolved in water then it dissociates as follows.
Whereas when HF is dissolved in aqueous solution then the reaction will be as follows.
Thus, we can conclude that out of the given options HF is the compound which will produce an acidic aqueous solution.
A chemical change is the answer
The volume of your 0.25 m stock solution that is needed to make 200 ml of 0.010 m NaCl is <u>0.008 L</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
Calculation:-
C₁ = 0.25 M
V₁ = ?
C₂ = 0.010 M
V₂ = 200 ml = 0.2 L
V₁ = C₂V₂/C₁
= 0.010 × 0.2 / 0.25
=<u> 0.008 L</u>
The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.
