Specific heat of Aluminium is 0.89 g/J
Explanation:
Step 1 :
Specific heat of a substance is the energy absorbed by a substance of unit mass when its temperature increases by one degree.
Energy Absorbed = Specific Heat * Mass of the substance * Temperature Difference
Step 2 :
It is given that 120 g sample absorbs 9612 J energy when the temperature increases from 298K to 388K.
Temperature Difference = 388 K - 298 K = 90 K
Step 3:
Specific Heat = (Energy Absorbed) ÷ (Mass of the substance * Temperature Difference)
Specific Heat = 9612 ÷ (120 * 90) = 0.89 grams / Joule
Step 4:
Answer:
Specific heat of Aluminium is 0.89 g/J
Answer:
Ingredient lists and nutritional facts
Explanation:
The packaged food, a consumer purchases has all its details written on the food package which is also verified by a trusted government institution.
The list tells each ingredient in food product by the food's common or usual name in the descending order by the weight.
- <u>Nutrition Facts Label
</u>
FDA requires this label on most of the packaged foods and the beverages. At top of Nutrition Facts label, there is written total number of the servings in container and serving size of food or drink. Serving size on label is based on amount of the food which people eat typically at one time. Rest of nutrition information on label is based usually on one serving of food or beverage.
One danger associated with blizzards is that blizzards are severe winter storms that pack a combination of blowing snow and wind resulting in very low visibilities. While heavy snowfalls and severe cold often accompany blizzards, they are not required. Sometimes strong winds pick up snow that has already fallen, creating a blizzard.
I hope this helps.
Answer:
No solution
Explanation:
36.9% w/w solution of butanoic acid in ethanol means 36.9 grams of butanoic acid per 100 grams of solution. The amount of butanoic acid in 120.0 g of the solution may be calculated:
(120.0 g solution)(36.9 g butanoic acid / 100 g solution) = 44.3 g butanoic acid.
There is not sufficient butanoic acid for the experiment.
