Have an amazing day!!
Please rate and mark brainiest!!
Answer:
1.08 M
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 45 mL
Initial concentration (C₁) = 6 M
Final volume (V₂) = 250 mL
Final concentration (C₂) =?
The final concentration of the solution can be obtained by using the dilution formula as illustrated below:
C₁V₁ = C₂V₂
6 × 45 = C₂ × 250
270 = C₂ × 250
Divide both side by 250
C₂ = 270 / 250
C₂ = 1.08 M
Therefore, the final concentration of the solution is 1.08 M.
I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
The answer is H₃C₆H₅O₇ (OPTION D).
In essence, the question is asking which of the options is an acid or a neutral compound; thus not a base. A base is a compound that accepts free hydrogen ions while in aqueous solution and as such they usually lack hydrogen ions that can be released in solution. If you ionize all the compounds/molecules above, the only on that has free hydrogen ions is OPTION D (which is an organic acid and not a base).
K2SO4 + BaBr2 -> 2KBr + BaSO4
BaSO4 is solid = precipitate
