State the optimum pH for sucrase activity and describe how sucrase activity changes at more acidic and more alkaline pH values.

Answers

Answer:

Explanation:

The rather high specific activity of intracellular sucrase towards sucrose is known to be optimal at pH 6.0 and at a temperature of about 30°C. And thus, we can say that the optimum pH for sucrase activity is exactly at 6. Also, it's behaviour is said to be decreasing with increasing acidic and increasing alkallinic values.

¿QUE DATO DE LA CONFIGURACIÓN ELECTRÓNICA TE PERMITE UBICAR LOS ELEMENTOS QUÍMICOS EN LA TABLA PERIÓDICA?

Answers

The question is: WHAT DATA OF THE ELECTRONIC CONFIGURATION ALLOWS YOU TO LOCATE THE CHEMICAL ELEMENTS IN THE PERIODIC TABLE?

Explanation:

Elements which have same number of valence electrons tend to show similar chemical properties due to which they are placed in the same group.

Hence, electronic configuration of an element tells us the number of valence electrons present in an element. As a result, it becomes easy to locate the element in its respective group.

Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions?
Boyle’s law
Charles’s law
Dalton’s law
Gay-Lussac’s law

Answers

Answer:

Gay-Lussac’s law

Explanation:

Gay-Lussac’s law is one of the gas laws discovered and proposed by a French scientist called Joseph Gay Lussac (1778 - 1850). In this law, it is stated that the pressure (P) of a gas varies directly with the absolute temperature (T) at a constant volume.

That is;

: P ∝ T

: P/T = K

Where:

P = pressure exerted by the gas

T = absolute temperature of the gas

K = the constant.

Hence, according to this question, the law that states that "the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions" is Gay-Lussac’s law.

Select four answers.


A. Lose energy

B. Gain energy

C. Move more

D. Move less

E. Become further apart

F. Become closer together

G. Overcome the attractive forces

H. The forces between them hold them more in place

Answers

Answer:

B, C, E, G

Explanation:

B - As particles are heated, they gain heat energy (or thermal energy, Q) from whatever the source may be.

C - Thermal energy particles gain is converted into kinetic, and the more KE/kinetic energy particles have, the more energy they have to move around.

E - When particles have more energy to move around more, they slide and move past each other and create more space; hence, they become further apart.

G - Eventually, particles will have enough energy and will move around so much that the attracting forces holding them together in the first place will be lesser than the particle's energy to break free and move from the attractive forces.

What volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution?​

Answers

So you add 1.4 L of 12M NaOH to 0.6 L of 2M NaOH to get 2 L of 9M NaOH.

The volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution is 1.4 L and 0.6 L

What is Concentration ?

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture.

Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

Amount of stuff = concentration x volume.

We can set up 2 equations:

V₁ = volume 12M NaOH.V₂ =  volume 2M NaOH.

(12×V₁) + (2×V₂) = 9×2 = 18

12V₁ + 2V₂ = 18 (1)

V₁ + V₂ = 2 (2)

From (2) we get:

V₁ = (2 − V₂)

Substituting  V₁ back into (1)  ⇒

12 (2−V₂) + 2V₂ = 18

24 − 12V₂ + 2V₂ = 18

10V₂ = 6

V₂ = 0.6L

From (2) we can say:

V₁ + 0.6 = 2

V₁ = 2 − 0.6 = 1.4L

Therefore, The volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution is 1.4 L and 0.6 L

Increasing the concentration increases the speed of reaction by... increasing the number of collisions between products increasing the amount of energy in the system increasing the number of collisions between reactants lowering the activation energy of the reaction

Answers

Answer: increasing the number of collisions between reactants

Explanation:

A reaction is possible due to collisions between the reactants to create products. If we increase the concentration of reactants then that means that we are increasing the molecules of the reactants which would give them more chances to collide and make products.

For instance, using a non-chemistry example, if there are few cars in a large city, the accidents there will be less because the cars will have such space that they wouldn't collide with each other. If the number of cars in the city is increased however, there is now less space and more chances for cars to collide.

A gas mixture contains 1.52 atm of Ne, 766 mmHg of He and Ar. What is the partial pressure, in atmospheres, of At if the gas mixture has a total pressure of 3.27atm

Answers

Answer:

0.74 atm.

Explanation:

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

Pressure of Ne (Pₙₑ) = 1.52 atm

Pressure of He (Pₕₑ) = 766 mmHg

Total pressure (Pₜ) = 3.27 atm

Pressure of Ar (Pₐᵣ) =?

Next, we shall convert the pressure of He from mmHg to atm. This can be obtained as follow:

760 mmHg = 1 atm

Therefore,

766 mmHg = 766 mmHg × 1 atm / 760 mmHg

766 mmHg = 1.01 atm

Finally, we shall determine the partial pressure of Ar. This can be obtained as follow:

Pressure of Ne (Pₙₑ) = 1.52 atm

Pressure of He (Pₕₑ) = 1.01 atm

Total pressure (Pₜ) = 3.27 atm

Pressure of Ar (Pₐᵣ) =?

Pₜ = Pₙₑ + Pₕₑ + Pₐᵣ

3.27 = 1.52 + 1.01 + Pₐᵣ

3.27 = 2.53 + Pₐᵣ

Collect like terms

3.27 – 2.53 = Pₐᵣ

Pₐᵣ = 0.74 atm

Thus the partial pressure of Ar is 0.74 atm.

Given the following reaction:

If you start with 8.3 mL of 9.9M sulfuric acid, what is the theoretical yield of alum?

Answers

Answer:

19.4 g of alum, will be its theoretical yield

Explanation:

The reaction is:

2 Al + 2 KOH + 4 H₂SO₄ + 22H₂O → 3H₂ + 2KAl(SO₄)₂•12H₂O

Let's determine the amount of acid.

M are the moles contained in 1 L of solution or it can be mmoles that are contained in 1 mL of solution

M = mmol /mL

M . mL = mmol

We replace: 8.3 mL . 9.9 M = 82.17 mmoles

We convert to moles: 82.17 mmol . 1 mol / 1000mmol = 0.082 moles

Ratio is 4:2

4 moles of sulfuric acid can make 2 moles of alum

By the way, 0.082 moles of acid may produce ( 0.082 . 2) /4 = 0.041085 moles.

We convert moles to mass:

Molar mass of alum is: 473.52 g/mol.

0.041085 moles . 473.52 g/mol = 19.4 g
