Answer:
Bring to the boil. Carefully place the can in the saucepan, ensuring there's enough water to completely cover the can at all times, topping up water frequently throughout the cooking process. Simmer, uncovered for 3 hours.
Answer:
Two types of substances will dissolve in water: ionic compounds, such as sodium chloride (NaCl, or table salt) and compounds composed of larger molecules that have a net charge due to the arrangement of their atoms. Ammonia (NH3) is an example of the second type.
Explanation:
The appropriate answer is d. the high specific heat capacity of water. This unique quality of water makes it suitable as an organic solvent. Specific heat capacity is the energy required to change one gram of a substance by one degree. Organic processes need to be carried out at a specific temperature. The high specific heat capacity of water ensures that environmental changes in temperature.
Answer:
The partial pressure of the gas produced by the reaction is 0.9187 atm
Explanation:
Given;
vapor pressure of water, 
= 0.0313 atm
measured atmospheric pressure, 
= 0.950 atm
partial pressure of the gas produced by the reaction = ?
According to Dalton's law of partial pressure; total pressure is equal to sum of partial pressure of water vapor and gas produced.
= 
= 0.95 - 0.0313
= 0.9187 atm
Therefore, the partial pressure of the gas produced by the reaction is 0.9187 atm
Answer:
evaporation means the state of the water went from liquid to gas which is a physical change. the sugar is still in the beaker which means its chemical properties did not change.
