Answer:
The entropy change in the environment is 3.62x10²⁶.
Explanation:
The entropy change can be calculated using the following equation:
Where:
Q: is the energy transferred = 5.0 MJ
: is the Boltzmann constant = 1.38x10⁻²³ J/K
: is the initial temperature = 1000 K
: is the final temperature = 500 K
Hence, the entropy change is:
Therefore, the entropy change in the environment is 3.62x10²⁶.

Concentration and ion moles are equal only when volume is 1. Of 1.0 x 10-6 and 1.0 x 10-4, the larger number is 1.
Answer:
0.954M solution
Explanation:
molarity = moles solute / volume solution in liters
=> molarity = 1.67 moles / 1.750 L soln = 0.954M solution
THE EXPLINATION ANSWER: I think crude oil is a mixture because it is made up of compounds that can be separated using distillation, a physical process.
The heat required to raise the temperature of the cup from 25 c to 50 c is calculated as follows
Q (heat) = c x delta T
c = specific heat capacity = 0. 820 j/c
delta T = change in temperature ( 50 c- 25 c = 25c
= 0.820 j /c x 25 c = 20.5 j
