Animals get energy from the food that they eat. However, when the molecules from the food enter your cells, how do the molecules

turn in to energy?
Question 3 options:

The glucose molecules from the food are broken down by the mitochondria in the cell to produce ATP which the cells use as energy.


The ATP is broken down into glucose which the cells use for energy.


Upon hitting the stomach, the food molecules are changed to energy molecules which fuel the body.


The cells absorb ATP from food and use it for energy.

A 225 g sample of an unknown solid is heated 67C and placed into a calorimeter containing 25.6 g of water at 15.6°c. If the fina
Stella [2.4K]

Answer:

= 1.271 J/g°C

Explanation:

Heat released by the metal sample will be equivalent to the heat absorbed by  water.

But heat = mass × specific heat capacity × temperature change

Thus;

Heat released by the solid;

= 225 g × c ×(67 -53) , where c is the specific heat capacity of the metal

= 3150 c joules

Heat absorbed by water;

= 25.6 g × 4.18 J/g°C × (53-15.6)

= 4002.0992  joules

Therefore;

3150 c joules = 4002.0992 joules

c =4002.0992/3150

 <u> = 1.271 J/g°C</u>

Why is it permissible to use a wet bottle when first obtaining your kmno4 solution?
Murrr4er [49]
For the answer to the question above, well presumably because the exact concentration of the composition KMnO4 solution doesn't matter. <span>If the concentration of the KMnO4 solution is important (usually in titrations etc.) then it is not allowed to use a wet bottle. The water in the bottle will dilute the KMnO4 solution and change the concentration of the said compound.</span>

Zn + O2= ZnO<br><br> How many moles of zinc are needed to make 500. g of zinc oxide?​
s2008m [1.1K]

Answer:

5.15 moles

Explanation:

2zn + o2 = 2zno

5.15 2.57 5.15 moles

nzno=500/(16x2+65)= 5.15 moles

-> nzn = 5.15 x 2 ÷ 2 = 5.15 moles
