Answer:
carbon dioxide gas is the answer
Explanation:
Acid + Carbonates → Salt + Water + Carbon Dioxide gas
Answer:
The vapor pressure for the first solution at 20°C is 17.48 Torr.
The vapor pressure for the second solution at 20°C is 17.49 Torr.
Explanation:
1) mass of solute that is glucose = 10 g
Moles of glucose ,
Mass of water = m
Volume of water = V = 1L = 1000 mL
Density of water = 1 g/ml
Moles of water =
Vapor pressure of the solution =
Vapor pressure of the pure solvent that is water =
Mole fraction of solute=
The vapor pressure for the first solution at 20°C is 17.48 Torr.
2 ) mass of solute that is sucrose= 10 g
Moles of sucrose ,
Mass of water = m
Volume of water = V = 1L = 1000 mL
Density of water = 1 g/ml
Moles of water =
Vapor pressure of the solution =
Vapor pressure of the pure solvent that is water =
Mole fraction of solute=
The vapor pressure for the second solution at 20°C is 17.49 Torr.
I know that one are decomposers (like mushrooms)
Hi! I think the answer is option B. I hope
this helps, Goodluck :)
Then you will multiply the number of moles by 6.022×1023formula units/mol . To determine the molar mass of a compound, add the atomic weight on the periodic table in g/mol times each element's subscript. Since the formula unit CaO has no subscripts, they are understood to be 1
