Solution :
It is given that :
Weight of the antacid tablet = 5.4630 g
4.3620 gram of antacid is crushed and is added to the stomach acid of 200 mL and is reacted.
25 mL of the stomach acid that is partially neutralized required 13.6 mL of NaOH to be titrated for a red end point.
27.7 mL of 
solution is equivalent to 
of the original stomach acid. Therefore, 13.6 mL of NaOH will take x 
= 12.27 ml of the original stomach acid.
it will sink
Explanation:
the solid iron will sink because it is dense than the liquid iron I will sink and it will melt
It does not change the chemical in the composition of water. hope it helps
C. rate = k[C4H9Br]
The slow step is always the rate-determining step. In the slow step, C4H9Br is the only reactant and has a coefficient of 1, so it is first order in the rate law.
The solution is unsaturated.
Supersaturated is when you put so much powder it no longer dissolves.
