Can somebody help please

98 moles of H₂O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2HCl + CaCO₃ —> CaCl₂ + H₂O + CO₂

From the balanced equation above,

1 mole of CaCO₃ reacted to produce 1 mole of H₂O.

Finally, we shall determine the number of mole of H₂O produced by the reaction of 98 moles of CaCO₃. This can be obtained as follow:

From the balanced equation above,

1 mole of CaCO₃ reacted to produce 1 mole of H₂O.

Therefore, 98 moles of CaCO₃ will also react to produce 98 moles of H₂O.

Thus, 98 moles of H₂O were obtained from the reaction.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
