Answer:

d. Although the hydrolysis of ATP is thermodynamically favorable, without a catalyst the reaction occurs at a very slow rate because it has a large activation energy.

Explanation:

Hello!

In this case, since negative Gibbs free energies of reaction stand for thermodynamically favored processes, we can immediately rule out choices a. and b.

Moreover, since the reaction is slow without the presence of a catalyst, which the context of biochemistry is an enzyme, we infer that correct choice is d. Although the hydrolysis of ATP is thermodynamically favorable, without a catalyst the reaction occurs at a very slow rate because it has a large activation energy because the higher the activation energy the slower the reaction according to the Arrhenius equation.

Answer:

Yes you can use alligation for a type of liquid. Explanation: Alligation is an old and practical method of solving arithmetic problems related to mixtures of ingredients.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Thus, we can use allegation for any type of liquid.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.

Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Allegation is a form of liquid that we may utilize. Allegation is a time-tested and useful strategy for tackling mathematical issues involving combinations of elements.

Thus, we can use allegation for any type of liquid.

Answer:

Limiting reactant: Cl2.

Max mass of PCl3 = 41.44 g.

P4 leftover = 5.51 g.

Explanation:

Hello!

In this case, since the undergoing chemical reaction is:

[tex]P_4+6Cl_2\rightarrow 4PCl_3[/tex]

In order to compute the maximum amount of PCl3, it is necessary to compute the grams of this product produced by each reactant, just as shown below, whereas molar masses and mole ratios are used:

[tex]m_{PCl_3}^{by\ P_4}=14.3gP_4*\frac{1molP_4}{123.89gP_4} *\frac{4molPCl_3}{1molP_4} *\frac{137.33gPCl_3}{1molPCl_3} =63.41gPCl_3\\\\m_{PCl_3}^{by\ Cl_2}=32.1gCl_2*\frac{1molCl_2}{70.91gCl_2} *\frac{4molPCl_3}{6molCl_2} *\frac{137.33gPCl_3}{1molPCl_3} =41.44gPCl_3[/tex]

Thus, since chlorine gas yields fewer grams of PCl3 than P4 we infer Cl2 is the limiting reactant and 63.41 grams of PCl3 product are yielded.

Finally, for the excess reactant, we see a difference of 63.41-41.44=21.97g, so we can compute of the leftover of P4 as follows:

[tex]m_{P_4}^{leftover}=21.97gPCl_3*\frac{1molPCl_3}{137gPCl_3} *\frac{1molP_4}{4molPCl_3} *\frac{137.33gP_4}{1molP_4} =5.5gP_4[/tex]

Answer:

[tex]V_2=120L[/tex]

Explanation:

Hello!

In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:

[tex]P_1V_1=P_2V_2[/tex]

Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:

[tex]V_2=\frac{P_1V_1}{P_2}[/tex]

Thus, we plug in to obtain:

[tex]V_2=\frac{1atm*30L}{0.25atm}=120L[/tex]

Best regards!

The final volume of the balloon at the given altitude is 120 L.

The given parameters;

The final volume of the balloon at the given altitude is calculated by applying Boyles law as follows;

[tex]P_1 V_1 = P_2 V_2\\\\V_2 = \frac{P_1V_1}{P_2} \\\\V_2 = \frac{30 \times 1 }{0.25} \\\\V_2 = 120 \ L[/tex]

Thus, the final volume of the balloon at the given altitude is 120 L.

Answer:

There are 10.0 moles of beryllium oxide in a 250 grams sample of the compound.

Explanation:

We can calculate the number of moles (η) of BeO as follows:

[tex] \eta = \frac{m}{M} [/tex]

Where:

m: is the mass = 250 g

M: is the molar mass = 25.0116 g/mol

Hence, the number of moles is:

[tex] \eta = \frac{250 g}{25.0116 g/mol} = 10.0 moles [/tex]

Therefore, there are 10.0 moles of beryllium oxide in a 250 grams sample of the compound.

Answer:

the flux of sucrose is 9.072 × 10⁻⁷  kg sucrose / m² sec

Explanation:

Given the data in the question;

water-gelatin solution separating two different concentration solutions of sucrose; 5.1 wt % gelatin at 293 K; at this conditions diffusivity of sucrose in water gelatin solution is;

[tex]D_{AB}[/tex] =  0.252 × 10⁻⁹ m²/sec.

we know that; 1 L = 0.001 m³, 1mL = 0.001 L

[tex]C_{A1}[/tex] = 2.0 g sucrose/100 mL = 2.0 × 10⁻³ kg sucrose / 100 × 10 ⁻³ L

[tex]C_{A1}[/tex]  = 2.0kg sucrose / 100 L

[tex]C_{A1}[/tex] = 2.0 kg sucrose / 100 × 10⁻³ m³

[tex]C_{A1}[/tex]  =  20 kg sucrose / m³

[tex]C_{A2}[/tex] =  0.2 g sucrose/100 mL = 0.2 × 10⁻³ kg sucrose / 100 × 10⁻³ × 10⁻³ L

[tex]C_{A2}[/tex] = 2 kg sucrose / m³

Thickness ß = 5 mm = 5 × 10⁻³ m

Now, flux of sucrose in kg sucrose / m³sec will be;

using the formula, [tex]N_{A}[/tex] = [tex]D_{AB}[/tex] /ß ( [tex]C_{A1}[/tex] - [tex]C_{A2}[/tex] )

we substitute

[tex]N_{A}[/tex] = (0.252 × 10⁻⁹ m²/sec /  5 × 10⁻³ m) ( 20 kg sucrose / m³ - 2 kg sucrose / m³ )

[tex]N_{A}[/tex] = (0.252 × 10⁻⁶ / 5) × 18 kg sucrose / m² sec

[tex]N_{A}[/tex]  = 4.536 ×  10⁻⁶  / 5 kg sucrose / m² sec

[tex]N_{A}[/tex] = 9.072 × 10⁻⁷  kg sucrose / m² sec

Therefore, the flux of sucrose is 9.072 × 10⁻⁷  kg sucrose / m² sec

Explanation:

The energy the molecules must have in order to react. Hence, option D is correct.

Activation energy is the sufficient amount of energy necessary to initiate a chemical reaction.

It can also be said as the minimum amount of energy needed to energize molecules or atoms so that they can undergo a chemical reaction or transformation.

Hence, the energy the molecules must have in order to react.
