<u>Answer:</u> The temperature increase will be 31.70°C.
<u>Explanation:</u>
To calculate the increase in the temperature of the system, we use the equation:

where,
q = Heat absorbed = 36.5 kJ = 36500J
m = Mass of water = 275 g
c = Specific heat capacity of water = 
= change in temperature = ? °C
Putting values in above equation, we get:

Hence, the temperature increase will be 31.70°C.
Answer:
metals donate electrons to nonsmetals
Answer:
4.6 x 10⁻⁶
Explanation:
In scientific notation, the number should be written in between 1 - 10 and multiplied by 10 raised to a power.
In this case, the decimal place should be placed in-between the 4 and the 6. To do this, you must move the decimal place 6 digits to the right. When you move the decimal place to the right, the 10 should be raised to a negative number.
As such, 0.0000046 in scientific notation is 4.6 x 10⁻⁶.
