Answer:
The temperature is 30,92K
Explanation:
We use the formula PV=nRT. We convert the unit of pressure in kPa into atm.
101,325kPa----1atm
121kPa-------x=(121,3kPax 1 atm)/101,325kPa=1, 2 atm
PV=nRT---->T= (PV)/(RT)
T=(1,2 atm x 3L)/(1,42 mol x 0,082 l atm/K mol )= 30, 91721058 K
We can classify the ion molecules as follows:
PO4^3- = Bronsted Base
ClO2- = Bronsted Base
NH4+ = Bronsted Acid
HCO3- = Both
H2PO4- = Both
For a Bronsted-Lowry acid and bases, an acid is a proton (hydrogen ion) donor. A base is a proton (hydrogen ion) acceptor. Hope this answers the question. Have a nice day.
Answer:
The molarity of the diluted HCl solution: <u>M₂ = 0.045 M</u>
Explanation:
To find- the molarity of the diluted HCl solution (M₂)
Given- <u>For original HCl solution</u>-
Molarity: M₁ = 1.5 M, Volume: V₁ = 60.0 ml = 0.06 L (∵ 1L = 1000 mL)
Then this original solution is diluted to a volume of 2 L
Thus <u>for the diluted HCl solution</u>-
The Volume of the diluted HCl solution: V₂ = 2 L
<u>So the Molarity of the diluted HCl solution (M₂) can be calculated by the </u><u><em>dilution equation:</em></u>



<u>Therefore, the molarity of the diluted HCl solution: M₂ = 0.045 M</u>
