Answer:

The radius of the sun is 7x10^5 kilometers, and that of the Earth is about 6.4x10^3 kilometers. Use scientific notation to show that the Sun's radius is about 100 times the Earth's radius. The Sun's radius is 10^10 the Earth's radius.

267 moles of NADH are produced by the Citric Acid Cycle (CAC). How many moles of glucose needed to be broken down during glycoly

leva [86]

Answer:

45 moles

Explanation:

From glycolysis, 1 mole of glucose gives 2 moles of pyruvate which undergoes citric acid cycle.

1 mole of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 3 moles of NADH.

Also,

2 moles of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 6 moles of NADH.

Thus,

6 moles of NADH are produced from 2 moles of pyruvate or 1 mole of glucose.

1 mole of NADH is produced from 1/6 mole of glucose

267 moles of NADH are produced from $\frac {1}{6}\times 267$ moles of glucose.

<u>Thus, moles of glucose needed to be broken ≅ 45 moles</u>

Why do crisp packets become inflated at high altitudes? Again, explain in as great a detail as possible, using ideas about parti

Andrei [34K]

As you get higher the atmospheric pressure lowers. The pressure in the packet of crisps has the pressure at which it has been closed (pressure at the surface of the earth). This means that the air molecules in the packet press harder outside than the air molecules in the atmosphere press on the packet.

the pressure in a sealed plastic container is 108 kPa at 41 degrees Celsius. What is the pressure when the temperature drops to

Katarina [22]

<u>Answer:</u> The new pressure will be 101.46 kPa.

<u>Explanation:</u>

To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.

The equation given by this law is:

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are initial pressure and temperature.

$P_2\text{ and }T_2$ are final pressure and temperature.

We are given:

By using conversion factor: $T(K)=T(^oC)+273$

$P_1=108kPa\\T_1=41^oC=314K\\P_2=?kPa\\T_2=22^oC=295K$

Putting values in above equation, we get:

$\frac{108kPa}{314K}=\frac{P_2}{295K}\\\\P_2=101.46kPa$

Hence, the new pressure will be 101.46 kPa.

Sulfuric acid solid aluminum hydroxide to form liquid water and a solubale salt. What is the balance equation

Hatshy [7]

Balanced chemical equation for the reaction between sulfuric acid & solid aluminum hydroxide to form liquid water and a soluble salt is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those in which all entities are present in same amount on both sides of the chemical equation.

Balanced chemical reaction for the given compounds will be shown as:

3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O

Above chemical equation is the balanced equation as all atoms are present in same amount on the left side as well as on the right side of the reaction.

Hence balanced equation is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.
