Answer:
CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)
Explanation:
- Dissolution reactions are reactions that occur when a solute either in gaseous, liquid, or solid form dissolves in a solvent such as water to form a solution.
- In this case we are given Calcium carbonate (CaCO3) which undergoes dissolution according to the equation;
- CaCO3(aq) → Ca2+(aq ) + CO3 2-(aq)
- Then<em><u> the bicarbonate ion combines with two protons from water to form a weak acid H2CO3. The weak acid is then broken down to form CO2 and H2O since its unstable.</u></em> 
 
        
             
        
        
        
The right subject for this question is physics.
To calculate the work you use the formula:
Work = force * displacement 
Work = 2500 pounds * 30 feet = 75,000 pounds - feet
To calculate the power you use the formula: 
power = work / time
Power = 75,000 pound - feet / 30 seconds = 2300 pound-feet / second.
