Answer:
Explanation:
Hello,
In this case, for the considered reaction, the standard reaction entropy is computed considering the standard entropy of each product and reactant and their stoichiometric coefficients as shown below:
Thus, considering the ALEKS Data tab, we obtain:

Answer:
100 cal
Explanation:
Given data:
Mass of carbohydrate = 19 g
Mass of protein = 1 g
Mass of fats = 4 g
Solution:
The average calories content of
Protein 4 cal/g
Carbohydrate 4 cal/g
Fat 9 cal/g
Then,
1 g protein × 4 cal/g = 4 cal
4 g fat × 9 cal/g = 36 cal
19 g carb. × 4 cal/g = 76 cal
Total calories = 116 cal
Round to one significant figure = 100 cal
Answer: 0.18 M
Explanation:
Initial molarity, M1 = 0.8 M
Initial olume, V1 = 225 ml
Final volume, V2 = 1000 ml
Final Molarity, M2 = M1V1/V2
= 0.8 x 225/1000
= 0.18 M
Excess alcohol is removed by Vacuum filtration.
<h3>What is vacuum filtration?</h3>
- Vacuum filtration is a methodology where a tension differential is kept up with across the channel medium by clearing the air beneath the channel paper.
- Vacuum filtration gives a power on the arrangement notwithstanding that of gravity and builds the pace of filtration.
- Vacuum filtration is the standard strategy utilized for isolating a strong fluid blend when the objective is to hold the strong (for instance in crystallization).
<h3>How do you dry a product after vacuum filtration?</h3>
- The strong can be dried rapidly by washing the strong with an unpredictable fluid (methanol, CH3)2CO, or ether are normal) that the strong won't break up in. In the event that the filtrate is to be gathered, change the getting jar prior to washing.

Answer: <em>Running water, even at a trickle, helps prevent pipes from freezing. If you decide to use fuel-burning equipment, such as a kerosene heater, ensure it is vented to outside and kept clear of any vents. Keep garage doors closed if there are water supply lines in the garage.</em>
