Answer:
5511 J
Explanation:
Applying,
Q = Cm.................... Equation 1
Where Q = amount of heat required to convert ice, C = Heat of fusion of water, m = mass of ice
From the question,
Given: C = 334 J/g, m = 16.5 g
Substitute these values into equation 2
Q = 334(16.5)
Q = 5511 J
Hence, the amount of heat required is 5511 J
Answer:
Percent composition tells you which types of atoms (elements) are present in a molecule and their levels. Percent composition can also tell you about the different elements present in an ionic compound as well.
A because b is for photosynthesis
11.82 x 1 mole / (molar mass)
The molar mass = 197 g/mol
11.82 / 197 = .06
This statement is <u>TRUE.</u>
Explanation:
Due to the high heat capacity of water, it takes much more energy to have a gram of water raised by one degree compared to one gram of land. This is why during a hot day, the ground gets hotter faster than the adjacent oceans or adjacent lakes. It also takes water to lose the same amount of energy to have its temperatures drop by one degree as compared to land. During the night, therefore, this is why adjacent water bodies remain relatively warmer than land.
