Carbon dioxide and water pretty sure
Answer:
Beryllium has an electronic configuration of 1s2 2s2 in its natural state. When in an ion state of Be2+ it loses the electrons in a 2s shell and has a configuration of 1s2. This means that Be2+ has 2 electrons.
Push the pushbutton to the first stop before inserting the tip into the solution, and then put the tip in the solution tube.
There are 674 mg of calcium carbonate in a Rolaids tablet
<h3>Further explanation</h3>
Reaction
CaCO₃ + 2HCl ⇒ CaCl₂ + CO₂ +H₂O
V HCl = 24.65 ml
M HCl = 0.547
mol HCl :

ratio mol CaCO₃ : HCl = 1 : 2, so mol CaCO₃ :

mass of CaCO₃ (MW=100~g/mol) :
