I would say your answer is C, or the last one. Hope it helps
Answer:
Explanation:
Hello!
In this case, since this calorimetry problems can by analyzed by figuring out that the heat lost due to the combustion of C6H12O6 is gained by the water and the calorimeter which undergo the mentioned temperature rise, we can write:
Thus, by plugging in the given data, we obtain:
Next, we compute the moles of C6H12O6 by using its molar mass (180.18 g/mol) as shown below:
Thus, the value for q of the reaction turns out:
Best regards!
Answer:
The higher the pH is, the more the hydroxide ion concentration increases and the more basic the solution becomes.
Explanation:
- When the pH of a solution is less than 7, then solution is called acidic and as the pH decreases the concentration of Hydronium ion increases.
- When the pH is about 7, then the solution is said to be neutral. On the other hand, when the pH is greater than 7, the solution is is said to be basic and as the pH increases the concentration of Hydroxide ions increases.
- Therefore, An acidic solution has a higher concentration of hydrogen ions compared to the concentration of hydroxide ions.
