Answer: The heat required to melt 25.0 g of ice at 
is 8350 Joules
Explanation:
Heat of Fusion tells us how much energy is needed to convert 1g of a solid to a liquid at the same temperature.
Q = Heat absorbed = ?
m = mass of ice = 25.0 g
L = Latent heat of fusion of ice = 334 J/g
Putting in the values, we get:
Thus heat required to melt 25.0 g of ice at is 8350 Joules
Mass number minus atomic number equals neutrons.
234-92=142
Explanation:
This is expressing as a subject of a formula of a specie.
This equation is used in solving for specific heat capacity of a material;
equation:
c = 
First cross multiply:
c[M(T2 - T1)] = h
Then multiply both sides by 
:
x c[M(T2 - T1)] = x h
M(T2 - T1) = 
Multiply both sides by 
x M(T2 - T1) = 
T2 - T1 = 
Now rearrange to produce;
T1 = T2 +

Because Boron likes to lose 3 electrons when it undergoes ionization, we draw a boron ion like a helium atom, with just 2 electrons in the first shell, and 0 in the second
The bubbles that were observed after the mixing of the two substances is one of the products of the reaction. It is the carbon dioxide that is produced. To determine the mass of this gas produced, we need to remember the Law of conservation of mass where mass cannot be created or destroyed. With this, we can say that the total mass that goes in a process should be equal to the mass that is goes out of the process no matter what the reaction is. We do as follows:
Mass of reactants = mass of products
11.00 + 44.55 = 51.04 + mass of carbon dioxide
mass of carbon dioxide = 4.51 g
