Answer:
Change in internal energy (ΔU) = -9 KJ
Explanation:
Given:
q = –8 kJ [Heat removed]
w = –1 kJ [Work done]
Find:
Change in internal energy (ΔU)
Computation:
Change in internal energy (ΔU) = q + w
Change in internal energy (ΔU) = -8 KJ + (-1 KJ)
Change in internal energy (ΔU) = -8 KJ - 1 KJ
Change in internal energy (ΔU) = -9 KJ
Answer:
The total kg from the mixer: 
Evaporated water: 
Jam produced: 
Explanation:
Step by step:
1) Kg of mixture from the mixer
It says that crushed fruit is added to the mixer with the sugar and pectin.
The fruit added is 1000 kg
The sugar added is 1.22 kg sugar/1 kg crushed fruit:

The pectin added is 0.0025 kg pectin/1 kg crushed fruit:

The total kg from the mixer:

2) Evaporated water
To calculate the evaporated water it's important to have in mind that the mix goes from a concentration of 14 wt% to 67 wt%. This difference is because of the evaporated water. So:
Initial: 1000 kg of fruit with 14 wt% of solids

<em>This amount of solids is constant </em>
Final: The mass of solids is the same but now it represents the 67 wt%

and


3) Jam produced

Explanation:
Round to whatever decimal point is needed for your answer.
Answer:
<u>Scientists estimate that the human genome, for example, has about 20,000 to 25,000 protein-coding genes. ... In fact, compared to almost any other organism, humans' 25,000 protein-coding genes do not seem like many. The fruit fly Drosophila melanogaster, for example, has an estimated 13,000 protein-coding genes.</u>
