Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed = ?
m= mass of substance = 7.40 g
c = specific heat capacity = 
Initial temperature of the water =
= 29.0°C
Final temperature of the water =
= 46.0°C
Change in temperature ,
Putting in the values, we get:


The amount of heat energy in joules required to raise the temperature is 526 Joules
Answer:
a heterogeneous mixture is a mixture of two or more liquid substances that are immiscible that is they cannot mix
Explanation:
Fluorine: F-
Aluminium: Al3+
Bromine: Br-
3F2 + 2AlBr3 => 3Br2 + 2AlF3
