Answer:
0.0922 g
Explanation:
Number of moles of acid present = 25/1000 × 0.0981
= 0.00245 moles
Number of moles of base = 5.83/1000 × 0.104
= 0.000606 moles
Since the reaction of HCl and NaOH is 1:1
Number of moles of HCl that reacted with antacid = 0.00245 moles - 0.000606 moles
= 0.001844 moles
From the reaction;
CaCO3 + 2HCl ----> CaCl2 + H2O + CO2
1 mole of CaCO3 reacts with 2 moles of HCl
x moles of CaCO3 reacts with 0.001844 moles ofHCl
x = 1 × 0.001844/2
= 0.000922 moles
Mass of CaCO3 = 0.000922 moles × 100 g/mol
= 0.0922 g
The amount of atomic particles released by a radioactive material in a specific time is determined by the strong and the weak nuclear force. It is these forces that holds the nucleus of the atom and the force that needs to be overcome with to allow radioactive decay.

Answer:
i think the answer is B
Explanation:
i Unionistly dont know i just want points sorry
I would go with D. Oxygen is released as a gas after water is spilt.
This may not be right.
I hope this helps!
Have a Good Afternoon!
