The scientific form is a\times 10^x \left \{ {{a\ \textgreater \ 0} \atop {a\ \textless \ 10}} \right. So, the form of scientific notation is 786,000 = 7.86 \times 10^5

The answer to it is 7.86 x 10 power of 5, because you are moving the decimal to the right if it's positive. I hope that helps.

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.

Answer:

2812.6 g of H₂SO₄

Explanation:

From the question given above, the following data were obtained:

Mole of H₂SO₄ = 28.7 moles

Mass of H₂SO₄ =?

Next, we shall determine the molar mass of H₂SO₄. This can be obtained as follow:

Molar mass of H₂SO₄ = (1×2) + 32 + (16×4)

= 2 + 32 + 64

= 98 g/mol

Finally, we shall determine the mass of H₂SO₄. This can be obtained as follow:

Mole of H₂SO₄ = 28.7 moles

Molar mass of H₂SO₄ =

Mass of H₂SO₄ =?

Mole = mass / Molar mass

28.7 = Mass of H₂SO₄ / 98

Cross multiply

Mass of H₂SO₄ = 28.7 × 98

Mass of H₂SO₄ = 2812.6 g

Thus, 28.7 mole of H₂SO₄ is equivalent to 2812.6 g of H₂SO₄
