Answer:
The temperature of soup will decrease.
The soup will get as cold as the room temperature.
Answer:
2H₂O₂ → 2H₂O + O₂
Explanation:
H₂O₂ → H₂O + O₂
The above equation can be balance as illustrated below:
H₂O₂ → H₂O + O₂
There are 2 atoms of O on the left side and a total of 3 atoms on the right side. It can be balance by putting 2 in front of H₂O₂ and 2 in front of H₂O as shown below:
2H₂O₂ → 2H₂O + O₂
Now, the equation is balanced.
**** check ****
Element >>> Left Side >>> Right Side
H >>>>>>>>> 4 >>>>>>>>> 4
O >>>>>>>>> 4 >>>>>>>>> 4
I believe this is the best one:
B. The volume of water will increase if cooled from 3°C to 2°C.
I don't think D) because water expands from 4°C to 0°C
"When liquid water is cooled, it contracts like one would expect until a temp of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point."
