Answer:
what's the question? is it A
Potassium hydroxide is a strong base and hydrobromic acid is a strong acid. This implies that the pH of the end-point [neutralization] of their titration will be around pH 7. A good indicator for this kind of pH is bromthymol blue. This is because this indicator changes its colour at pH 7.
Answer:
Mass stays the same but weight decreases due to a lack of gravity
Answer:
The answer is c
. Single Replacement
Explanation:
A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.
Let's see
- ∆S refers to the total change in entropy of system.
Graphite was in solid state and oxygen was in gaseous state.
When they synthesized they converted to gaseous state
- So randomness of particles increases
- So entropy also increases
∆S=+ve
