The answer is 2.25 hours, or 2 hours and 25 minutes.
9.50-5=4.50
4.50/2=2.25
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in 
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when 
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that 
, 
, 
and 
, then the cooling rate of the substance is:
The cooling rate of the substance is approximately 0.0732.

I agree. because you never know. you might go to the career and you dont like so you have to research about it to get a great job
Answer:
Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1
Explanation:
Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0
Electronegativity difference in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1
Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
