Rank these molecules or groups of molecules by when mammals use them as fuel, from right after a meal through only during starva
Natalka [10]

The question is incomplete: the complete question is:

Rank molecules or group of molecules by when mammals use as fuel, starting right after meal to only through?

starvation.

a) glucose from glucose-2-phosphate from glycogen.

b) free glucose and amino acids

c) fatty acids from triglycerides

d) glucose produced from amino acids in liver.

Answer:

B

A

C

D

Explanation:

Free glucose and amino acid enters into the blood stream directly and can be used immediately after meals by mammals.

The liver stores excess glucose as glycogen, hence when glucose levels begin to reduce in the body, the pancreas releases glucagon which converts glycogen to glucose.

Triglycerides are broken down to give fatty acids which gives much more energy than glucose.

During starvation, amino acids in the liver is converted to glucose when a person goes for days without eating.

Silver is a precious metal. The price of silver fluctuates daily as it is traded on the open market. Look up the current market
Vlad [161]

Answer:

- Current market value of silver produced in the experiment = $0.2763

- Check Explanation for the appearance of leftover copper wire used in the experiment.

Explanation:

Price of Silver on today's market = $15.34 per troy ounce

Amount of Silver produced in the experiment = 0.56 g

31.1 g = 1 troy ounce

0.56 g = (0.56/31.1) = 0.01801 troy ounce

1 troy ounce = $15.34

0.01801 troy ounce = 0.01801 × $15.34 = $0.2763

The original reaction to extract the silver is one between Copper metal and the Silver Nitrate.

The Copper metal dissolves in the Silver Nitrate to give Copper Nitrate thereby displacing the Silver ion to become silver metal which we just valued above. But copper nitrate is a blue solution, So, it is a good estimate to say that the entire solution changed to that blue colour and the appearance of the leftover copper metal is colour blue. The silver metal forms as fractal-like crystals on this leftover copper.

Hope this Helps!!!

Why is zinc not extracted from ZnO through reduction using CO?​
Jet001 [13]
The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO

What is the amount of heat released by 1.00 gram of liquid water at 0°C when it changes to 1.00 gram of ice at 0°C?
QveST [7]

Answer:

334J/g

Explanation:

Data obtained from the question include:

Mass (m) = 1g

Specific heat of Fusion (Hf) = 334 J/g

Heat (Q) =?

Using the equation Q = m·Hf, we can obtain the heat released as follow:

Q = m·Hf

Q = 1 x 334

Q = 334J

Therefore, the amount of heat released is 334J

My Everest is the highest mountain on earth.its height is 8.848 km. Convert this height to feet. Write your answer in standard n
Vinvika [58]

Answer: 2.9(10)^{7} ft

Explanation:

Firstly we need to know that 1 km=3280.84 ft, then we cam make the conversion:

8848 km \frac{3280.84 ft}{1 km}=29,028,872.32 ft This is the height of Mount Everest in feet

However, we can express it using scientific notation by counting to the left the decimal spaces:

29,028,872.32 ft \approx 2.9(10)^{7} ft
