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

What is lactase?

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.

what would be a logical explanation for why carbon dioxide increased over the time shown in the graph.
A. the area of land for crops incresed
b. the amount of plants eaten by animal increased
c. the amount of fossil fuels being burned increased
d. the amount of wood being burned by pepole increased

Answers

Answer:

c. the amount of fossil fuels being burned increased

Explanation:

Carbon dioxide gas concentration increased over the time due to burning of fossil fuels increased. Fossil fuels are organic compounds which releases carbondioxide gas as a result of burning of fossil fuels in the engines of vehicles and industries. With the passage of time, number of vehicles increases in the world which needs more fossil fuels and due to burning of that fossil fuels, more carbondioxide gas is released.

The density of gold is 19.3 g/cm³. Which of the following shows the mass of a gold bar that is 4.50 cm × 8.00 cm × 20.00 cm?

Answers

Answer:

13896g

Explanation:

volume = 4.50×8.00×20.00 = 720 cm³

mass = density × volume

mass= 19.3 × 720 = 13896g

A 1.00-L flask was filled with 2.00 moles of gaseous and 2.00 moles of gaseous and heated. After equilibrium was reached, it was found that 1.21 moles of gaseous 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.

Answers

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
