Enzyme lactase catalyzes the hydrolysis of the glycosidic bond of lactose to form galactose and glucose.

Lactase can be described as an enzyme produced by many organisms. Lactase is located in the small intestine of humans and other mammals. It is essential to accomplish the digestion of milk and it breaks down lactose that gives milk its sweetness.

A person with a deficiency of lactase, and who consume dairy products, may experience the symptoms of lactose intolerance. Lactase is a part of the β-galactosidase family of enzymes and is a glycoside hydrolase involved in the hydrolysis of lactose into constituent galactose and glucose monomers.

The β-glycosidic bond in D-lactose in metabolism is hydrolyzed to form D-galactose and D-glucose, which can be absorbed into the bloodstream. The optimum temperature of the human lactase is about 37 degrees Celcius and the optimum pH of the human lactase is equal to 6.

Answer:

Solar energy is essentially the light and heat emitted from the sun

Answer:chlorophyll

Explanation:

The part of leaves that is responsible for absorbing sun's energy is chloroplast.

A chloroplast is an organelle found within the cells of plants and certain algae that is responsible for photosynthesis, which is the process by which solar energy is converted into chemical energy for growth.

Small organelles called chloroplasts are found inside plant cells and store sunlight energy.

The chloroplast's thylakoid membranes contain a light-absorbing pigment called chlorophyll, which is responsible for the plant's green color.

They are in charge of photosynthesis, which is the process of converting light energy into sugar and other organic molecules that plants and algae use as food.

They also produce amino acids and lipids, which are required for the production of chloroplast membranes.

Thus, the chloroplast is the part that traps the energy of the Sun.

Jupiter is a very large planet. Larger planets usually have stronger gravity, which pulls planets toward each other.

The moons of Jupiter are by Jupiter. (I know, that wasn't a smart thing to say because you know that, but, hey, I had to.) With this being the case, Jupiter is also an inside planet.

- Inside Planets

Planets that are closest to the sun and orbits the sun

There are 2 things that are the cause of the moons of Jupiter not being pulled by earth.

1. Jupiter has strong gravity which pulls the moons, and Jupiter is being pulled by the sun's INCREDIBLE gravity.

2. Earth is an outside planet. It is too far away from Jupiter to attract Jupiter's moons.

- Outside Planet

A planet that is away from the sun, but still orbits the sun

Answer:

40 Grams

Explanation:

Fe2O3 is 2 parts Iron 3 parts Oxygen.

Assuming the molecular weights of both are equivalent (ideal elemental law), it is a 2:3 ratio, or 2/5 of the total.

2/5 of 100 is 40, so the answer is

40 grams

Answer:

2450 mg

Explanation:

From the given information:

The total weight of the capsule = 12.5 mg + 37.5 mg

= 50 mg

The percentage of drug in each capsule = [tex]\dfrac{12.5}{50} \times 100[/tex]

= 25%

= 0.25

To make 0.5 mg of drug in each  100 mg of powder after dilution;

Then, the drug percent in each capsule after dilution is:

[tex]=\dfrac{0.5}{100}\times 100[/tex]

= 0.5%

= 0.005

Suppose (p) mg represent the amount that is added to the diluent in the given capsule. Then;

The total amount is = (50 + p) mg

Since the amount of the drug = 12.5 mg

Then the concentration  [tex]=\dfrac{12.5}{50 + x}[/tex] which needs to be equal to the needed concentration that is diluted.

i.e.

[tex]\dfrac{12.5}{50 + x} = 0.005[/tex]

By cross multiply;

(50 + x) 0.005 = 12.5

(50 × 0.005) + (0.005x) = 12.5

0.25 + 0.005x = 12.5

0.005x = 12.5 - 0.25

0.005x = 12.25

x = 12.25 / 0.005

x = 2450 mg

Thus, there is a need for an additional 2450 mg to make a dilution that compass 0.5 mg of drug in 100 mg powder.

Explanation:

Explanation:

Metals usually have stronger electron affinity than non-metals:

In the periodic table, the trend of electron affinity is that it increases from left to right across the period and decrease down the group.

False

Noble gas elements have a very large value for electron affinity:

Electron affinity is the change in energy of an atom when an electron is added. Noble gases already have a complete octet configuration hence there is no reason to accept any electrons. This makes their electron affinity value less than or equal to zero.

False

Negative anions have a larger ionic radius than the atomic radius of their neutral atom:

Neutral atoms that gain electron are referred to as anions. The extra electron increases the electron-electron repulsion which pushes the electrons further apart and finally increased radius.

Answer:

Explanation:

In one mole of carbon, there are 6.02×10^23 atoms. So in two moles, there will be twice that: 1.204×10^24

Answer:

1. 5.24 g

2. 75.4%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

MgCl₂ + Na₂SO₄ —> MgSO₄ + 2NaCl

Next, we shall determine the mass of MgCl₂ that reacted and the mass of MgSO₄ produced from the balanced equation. This can be obtained as follow:

Molar mass of MgCl₂ = 24 + (35.5×2)

= 24 + 71

= 95 g/mol

Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g

Molar mass of MgSO₄ = 24 + 32 + (16×4)

= 24 +32 + 64

= 120 g/mol

Mass of MgSO₄ from the balanced equation = 1 × 120 = 120 g

SUMMARY:

From the balanced equation above,

95 g of MgCl₂ reacted to produce 120 g of MgSO₄.

1. Determination of the ideal yield of magnesium sulfate, MgSO₄.

From the balanced equation above,

95 g of MgCl₂ reacted to produce 120 g of MgSO₄.

Therefore, 4.15 g of MgCl₂ will react to produce = (415 × 120)/95 = 5.24 g of MgSO₄.

Thus, the ideal yield of magnesium sulfate, MgSO₄ is 5.24 g

2. Determination of the percentage yield.

Actual yield of MgSO₄ = 3.95 g

Ideal yield of MgSO₄ = 5.24 g

Percentage yield =?

Percentage yield = Actual yield / Ideal yield × 100

Percentage yield = 3.95 / 5.24 × 100

Percentage yield = 395 / 5.24

Percentage yield of MgSO₄ = 75.4%

Answer:

2.35

Explanation:

A 1.00-L flask was filled with 2.00 moles of gaseous SO₂ and 2.00 moles of gaseous NO₂ and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous NO was present. Assume that the reaction

SO₂ + NO₂ ⇌ SO₃ + NO

occurs under these conditions. Calculate the value of the equilibrium constant, K, for this reaction.

Step 1: Calculate the molar concentrations

Since the reaction takes place in a 1.00 L flask, the molar concentrations are:

[SO₂]i = 2.00 M

[NO₂]i = 2.00 M

[NO]eq = 1.21 M

Step 2: Make an ICE chart

        SO₂ + NO₂ ⇌ SO₃ + NO

I       2.00   2.00       0        0

C        -x       -x         +x       +x

E    2.00-x  2.00-x    x         x

Step 3: Calculate the concentrations at equilibrium

The concentration of NO at equilibrium is 1.21 M. Then, x = 1.21.

[SO₂]eq = 2.00-1.21 = 0.79 M

[NO₂]eq = 2.00-1.21 = 0.79 M

[SO₃]eq = x = 1.21 M

[NO]eq = x = 1.21 M

Step 4: Calculate the value of the equilibrium constant, K, for this reaction

K = [SO₃] × [NO]/[SO₂] × [NO₂]

K = 1.21²/0.79² = 2.35
