Answer:
H2SO4 cannot be used with CaCO3 to produce CO2 gas
Explanation:
Because it does not dissolve in water- it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume CO2 is produced, this stops in short time.
I hope this helps :)
A) Moles
When converting the volume of a gas to the mass of a gas, the first step is to convert volume to moles.
Answer:
10.0g of solute before reaching saturation
Explanation:
A saturated solution is the solution that contains the maximum amount of solute that can be dissolved. In the problem, you can have
50.0g of solute / 500.0g Solvent
Now, in 800.0g solvent you can dissolve:
800.0g Solvent * (50.0g solute / 500.0g Solvent) = 80.0g of solute can be added
As you dissolve initially 70.0g of solute. You can add:
80.0g - 70.0g =
<h3>10.0g of solute before reaching saturation</h3>
One possible answer could be that a chemical reaction has occurred.
Given the balanced equation representing a reaction: Zn(s) + 2HCl(aq) + H2(g) + ZnCl2(aq) Which statement is true about energy in this reaction? A. The reaction is exothermic because it releases heat.
