First write and balance the equation, being:
CaCO3 - CaO + CO2
Then, using the periodic table, find the molecular masses of CaCO3 and of CaO, finding their ratio. That will be 100g:56g or 0.1kg:0.056kg. Since you have 4.7kg of CaCO3, it corresponds to Xkg of CaO. Making x the subject, it should be X= 4.7*0.056/100=0,002632
Answer: The law of corresponding states is an empirical law according to which the equations of states for real gases are similar when these gases are expressed in reduced temperature, pressures, and volumes at critical point.
The molecular formula of glucose:
C₆H₁₂O₆
Answer:
Yes, water molecules becomes gas particles when the vapor pressure is lower than the external atmospheric temperature.
Explanation:
Vapor pressure is defined as the pressure of the vapor that lies above its surface. In other words, it is the pressure of the vapor which results from the evaporation of a liquid which is above a liquid in a closed or open container.
The liquid starts boiling or evaporation takes place when the vapor pressure of the liquid becomes equal to the external or atmospheric pressure. Now when the vapor pressure is less than the atmospheric pressure, the liquid boils at a higher temperature while when vapor pressure is more than the atmospheric temperature, the liquid starts boiling a lower temperature.
