Answer:
The heat required to change 25.0 g of water from solid ice to liquid water at 0°C is 8350 J
Explanation:
The parameters given are
The temperature of the solid water = 0°C
The heat of fusion, = 334 J/g
The heat of vaporization, = 2260 J/g
Mass of the solid water = 25.0 g
We note that the heat required to change a solid to a liquid is the heat of fusion, from which we have the formula for heat fusion is given as follows;
ΔH = m ×
Therefore, we have;
ΔH = 25 g × 334 J/g = 8350 J
Which gives the heat required to change 25.0 g of water from solid ice to liquid water at 0°C as 8350 J.
Answer:
D
Explanation:
If you add two or more thermochemical equations to give a final equation, then you also add the heats of reaction to give the final heat of reaction
<span>The Helium gas will expand and rise into the surrounding the air as it is less dense and lighter air. Depending on the amount of helium and the size of the room the Helium could displace the breathable mix in the space and become a danger to health.</span>
