It I c because it is asking is the wind hard
Enough
Explanation:
The given reaction is as follows.
The number of elements on reactant side are as follows.
The number of elements on product side are as follows.
Therefore, the equation is completely balanced.
Thus, we can conclude that only one formula units of calcium chloride must be part of the products.
Answer:
e. H₂O
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of the substance in 1 unit. If you have to warm your room, you have to choose the substance with the <u>highest</u> specific heat capacity value. This substance will retain the highest amount of heat. From the options, the highest value is 4.184 J/g°C (water, H₂O). Thus, 1 gram of water will retain 4.184 J when the temperature is raised to 1°C. That is a higher amount of heat in comparison with, for example, granite, which is able to retain 0.79 J per gram when the temperature is raised to 1°C.
However, you have to consider that the boiling point of water is 100°C, so the temperature at which you have to warm the room is the temperature at which water will be passing to the gas state.
