1550J
Explanation:
Given parameters:
Heat of fusion = 155J/g
Mass of sample = 10g
Unknown:
Quantity of heat removed to freeze the substance =?
Solution:
This is a phase change problem and we apply the formula for the specific heat of fusion to solve the problem:
Q = mL
m is the mass of the substance
L is the specific heat of fusion of the substance.
We then plug the parameters into the equation:
Q = 155J/g x 10g = 1550J

Answer:
Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon
Explanation:
Given expression:
C₂H₄ + O₂ → 2H₂O + 2CO₂
The law of conservation of mass suggests that chemical equations be balanced since atoms are neither created nor destroyed in the course of a chemical reaction. In retrospect, bonds are broken and chemical species are change to another form.
From the given equation, only oxygen is not balanced. This flouts the law of conservation.
On the reactant side, we have 2 oxygen on the product, we have 6.
Answer:
High and low pressure regions form when there is a large temperature difference between the surface of the sea (or a large lake) and the land next to it. Local winds are created as a result of this. Warmer air from the ocean rises and then sinks on land, causing the temperature to rise over the land.
