Fronts. This includes cold fronts and warm fronts. Hoped this helped!
Answer:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range.
(2) The rate of heating does not matter.
Explanation:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range, because varying temperature range across the body will lead to inaccurate determination of melting point.
(2) In principle, the melting temperature is INDEPENDENT (not dependent) on the heating rate. so in other words, altering the heating rate does not affect the measure of melting point.
The enthalpy change, ΔH for the following reaction
is -452.76 kJ.
<h3>What is enthalpy change, ΔH, of a reaction?</h3>
The enthalpy change of a reaction is the heat changes that occurs when a reaction proceeds to formation of products.
- Enthalpy change, ΔH = ΔH of products - ΔH of reactants
The equation of the reaction is given below



Therefore, the enthalpy change, ΔH for the following reaction
is -452.76 kJ.
