What is the meaning of ground state energy?​

Answer:

114.23g

Explanation:

Mass = xg

Mole = 0.334 mol

Molar mass of Sucrose

(C = 12, H = 1, O = 16)

C12H22O11

(12×12)+(1×22)+(16×11)

144 + 22 + 176

342g/mol

Mass = No of mole × Molar mass

Mass = 0.334 × 342

Mass = 114.228

Mass ≈ 114.23g

Answer:

35.7 mL NaOH

Explanation:

M1V1 = M2V2

M1 = 0.100 M NaOH

V1 = ?

M2 = 0.102 M HI

V2 = 35.0 mL

Solve for V1 --> V1 = M2V2/M1

V1 = (0.102 M)(35.0 mL) / (0.100 M) = 35.7 mL NaOH

Answer:

pH = 11.216.

Explanation:

Hello there!

In this case, according to the ionization of ammonia in aqueous solution:

[tex]NH_3+H_2O\rightleftharpoons NH_4^++OH^-[/tex]

We can set up its equilibrium expression in terms of x as the reaction extent equal to the concentration of each product at equilibrium:

[tex]Kb=\frac{[NH_4^+][OH^-]}{[NH_3]} \\\\1.80x10^{-5}=\frac{x*x}{0.150-x}[/tex]

However, since Kb<<<1 we can neglect the x on bottom and easily compute it via:

[tex]1.80x10^{-5}=\frac{x*x}{0.150}\\\\x=\sqrt{1.80x10^{-5}*0.150}=1.643x10^{-3}M[/tex]

Which is also:

[tex][OH^-]=1.643x10^{-3}M[/tex]

Thereafter we can compute the pOH first:

[tex]pOH=-log(1.643x10^{-3}M)\\\\pOH=2.784[/tex]

Finally, the pH turns out:

[tex]pH=14-2.784\\\\pH=11.216[/tex]

Answer:

A. Bees bringing pollen from the flower of one plant to the flower of another plant.

Explanation:

Genetic diversity in organisms is enhanced by the process of sexual reproduction due to the meiotic process that the participant organisms undergo to produce gametes. A process unique to meiosis called CROSSING OVER ensures that the alleles of genes are recombined in the GAMETE or sex cells.

According to this question, POLLINATION, which is the transfer of pollen from a male flower to a female one, will lead to sexual reproduction via fertilization. However, a cross-pollination, which requires a pollinator like the bees in this question will ensure the most genetic diversity among the offsprings.

Answer:

Aluminium is a highly reactive metal yet it is used to make utensils for cooking this is because aluminium reacts with oxygen present in air to form a thin layer of Aluminium oxide is oxide layer is very stable and prevent for the reaction of aluminium with oxygen

To answer this problem we can use Gay-Lussac's law, which states:

Now we convert the given temperatures into K:

We input the data:

And solve for P₂:

Answer:

Explanation:

Mass = 66.6 gram

Density = 0.790 g/mL

Volume = Mass ÷ Density

Volume = 66.6 ÷ 0.790

Volume = 84.30 mL

Answer:

carbon

Explanation:

The properties of carbon forms the basis for all life. Explanation: The atoms of carbon are found in the molecules of all living species.

Answer:

750 mmHg

Explanation:

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

Partial pressure of CO₂ (Pₐ) = 250 mmHg

Partial pressure of N₂ (P₆) = 375 mmHg

Partial pressure of He (P꜀) = 125 mmHg

Pressure of the mixture (Pₜ) =?

The pressure of the mixture of the gases can be obtained as follow:

Pₜ = Pₐ + P₆ + P꜀

Pₜ = 250 + 375 + 125

Pₜ = 750 mmHg

Therefore, the pressure of the mixture of the gases is 750 mmHg

Answer:

5.68g

Explanation:

Answer:

2.57 moles of carbon

Explanation:

1 mole = 6.023x10^23 (this is called avogadro's number)

1/6.023x10^23

1.55x10^24 = 1.55x10^24/6.023x10^23 = 2.57 moles

this means, 1.55x10^24 atom contains 2.57 moles of carbon
