WOW! I have the same question! Again lol.

A similarity is that both are at the same temperature and a difference is both are at different states of matter between the particles in liquid water at 100ºC and the particles in steam at 100ºC.

There are only 3 states in which matter is present in the universe that is solid, liquid and gas, and on the basis of molecular space, they are differentiated in their respective category.

The water present both at 100ºC first is in a liquid state where molecules of water are more close as compared to the molecules of the steam water but the temperature for both is the same.

Therefore, the similarity is that both are at the same temperature and a difference is both are at different states of matter between the particles in liquid water at 100ºC and the particles in steam at 100ºC.

dispersion.

Explanation:

The molecule, PF2Cl3 is trigonal bipyramidal. The dipoles in the molecule cancel out since there is a symmetric charge distribution around the molecule hence the resultant dipole moment of the molecule is zero.

If the molecule is nonpolar, then the dominant intermolecular forces present are the weak dispersion forces, hence the answer above.

Answer:  The correct answer would be : "A bottle that is sealed".

I hope that this helps you !

A 1-L soda bottle contains dissolved carbon dioxide gas then the bottle which have the highest concentration of dissolved gas is a bottle that is sealed.

Carbon dioxide is easily dissolved in water or soda to make tiny bubbles and it prevents the growth of bacteria during the preservation of sodas.

This dissolved carbon dioxide gas coming out in the form of effervescence when we open a bottle of soda. So, in the sealed bottle of soda higher concentration of dissolved carbon dioxide gas is present. And if we open the seal then the amount of dissolved carbon dioxide decreases from the bottle.

Answer:

a. Conversion of A to C is exergonic.

Explanation:

In the problem:  C→ B occurs with ΔG = + 16 kJ/mol

It is possible to sum ΔG of reactions to obtain ΔG of another related reaction:

A → B ΔG = -14kJ/mol

C → B ΔG = +16kJ/mol

A → C ΔG = -14kJ/mol - (+16kJ/mol) = -30kJ/mol

As ΔG < 0

The reaction is exergonic

Under these condition, the reaction occurs. But under another conditions, the reaction will be at equilibrium (ΔG = 0)

A reaction is entropically driven if ΔG < 0 and ΔS is high. But we don't have information of ΔS.

As ΔG <0, the reaction is not spontaneous in the reverse direction

Answer:

495 pm (see the relationship between the edge length (a) and radius (r) of atoms in attachment).

Explanation:

A crystalline solid possess rigid and long-range order; its atoms, molecules, or ions occupy specific positions. A unit cell is the basic repeating structural unit of a crystalline solid. Each sphere in the unit cell represents an atom, ion, or molecule and is called a lattice point. The way the spheres are arranged in layers determines what type of unit cell we have.

In the face-centered cubic cell, there are spheres at the center of each of the six faces of the cube, in addition to the eight corner spheres (see the second picture in the attachment). Each sphere in this arrangement is said to have a coordination number of 12 since each sphere is in contact with six spheres in its own layer, three spheres in the layer above, and three spheres in the layer below. The coordination number is defined as the number of atoms (or ions) surrounding an atom (or ion) in a crystal lattice.

In the first picture in the attachment we can see that the relationship between the atomic radius r and the  edge length a face-centered  cubic cell is:

a=√8*r

Therefore, the edge length will be √8*175 pm = 495 pm

FCC Stands for Face Centered Cubic

The formula that is used to find edge length is:

[tex]a=\sqrt{8}*r[/tex]

where

a= edge length

r= radius

Given:

r= 175 pm

Substituting the values in the above formula.

[tex]a=\sqrt{8}*175\\\\a=495 pm[/tex]

Therefore, the edge length will be 495 pm.

Answer:

2.954grams of pottasium for that week

Explanation:

According to this question, a medium-sized that weighs 118grams contains 422 milligrams (mg) of potassium nutrient.

If someone eats a medium-sized banana each day for a week, this means that the person has consumed 422mg of pottasium that day.

Since there are 7days in a week, the person will consume 422 × 7 = 2954 mg of pottasium that week.

The question asks for the total pottasium intake in grams for that week, hence, we need to convert 2954 milligrams to grams.

1000mg = 1 g

Hence, 2954mg will be 2954/1000

= 2.954grams

Therefore, 2.954grams of pottasium are ingested by that person that week.

5.14×10⁻⁶ moles of C

6.43×10⁻⁶ moles of H

2.57×10⁻⁶ moles of N

1.28×10⁻⁶ moles of O

Explanation:

To determine the moles of each compound we need to know the molar mass of them

Subscripts number of compounds are the number of moles, of each atoms.

For example, H₂O. 1 mol of water has 2 moles of H and 1 mol of O.

a. KBr → 119 g/mol

We convert the mass to moles (mass/molar mass)

2.12 g / 119 g/mol = 0.0178 moles of bromide

1 mol of potassium bromide has 1 mol of K and 1 mol of Br, then 0.0178 moles of salt, will have:

0.0178 moles of K

0.0178 moles of Br

b. H₃PO₄ → 97.97 g/mol

0.1488 g / 97.97 g/mol = 1.52×10⁻³ moles of acid.

1 mol of phosphoric acid has 3 moles of H, 1 mol of P and 4 moles of O

Then 1.52×10⁻³ moles of acid. will have:

(1.52×10⁻³ . 3) / 1 = 4.55×10⁻³ moles of H

1.52×10⁻³ moles of P

(1.52×10⁻³ . 4) / 1 = 6.07×10⁻³ moles of O

c. CaCO₃ → 100.08 g/mol

23000g / 100.08 g/mol = 229.8 moles

(notice, we convert the kg to g, before)

1 mol of calcium carbonate has 1 mol of Ca, 1 mol of C and 3 moles of O

Then 229.8 moles of salt will have

229.8 moles of Ca

229.8 moles of C

(229.8 . 3) / 1 = 689.4 moles of O

d. Al₂(SO₄)₃ → 342.15 g/mol

78.452 g / 342.15 g/mol = 0.229 moles

1 mol of Al₂(SO₄)₃ has 2 moles of Al, 3 moles of S and 12 moles of O

Then  0.229 moles of sulfate will have:

(0.229 . 2) / 1 = 0.458 moles of Al

(0.229 . 3) / 1 = 0.687 moles of S

(0.229 . 12) / 1 = 2.75 moles of O

e. C₈H₁₀N₄O₂  → 194.19 g/mol

0.0001250 g / 194.19 g/mol = 6.43×10⁻⁷ moles

(Notice, we convert mg to g)

1 mol of caffeine has 8 moles of C, 10 moles of H, 4 moles of N and 2 moles of O

Then, 6.43×10⁻⁷ moles of caffeine will have:

(6.43×10⁻⁷ . 5) / 1 = 5.14×10⁻⁶ moles of C

(6.43×10⁻⁷ . 10) / 1 = 6.43×10⁻⁶ moles of H

(6.43×10⁻⁷ . 4)/1 = 2.57×10⁻⁶ moles of N

(6.43×10⁻⁷ . 2)/ 1 = 1.28×10⁻⁶ moles of O

Answer:

[tex]W = 6.65 \cdot 10^{6} lbf[/tex]

Explanation:

To find the weight (W) of the pond contents first we need to use the following equation:

[tex] W = m\cdot g [/tex]   (1)

Where m the mass and g is the gravity  

Also, we have that the mass is:

[tex]m = \rho*V[/tex]  (2)    

Where ρ is the density and V the volume

We cand calculate the volume as follows:

[tex] V = L*w*d [/tex]   (3)

Where L is the length, w is the wide and d is the depth  

By entering equation (2) and (3) into (1) we have:

[tex]W = \rho*L*w*d*g[/tex]

[tex] W = 75.3 lbm/ft^{3}*50 m*25 m*2 m*9.81 m/s^{2} [/tex]  

[tex]W = 75.3 lbm/ft^{3}*\frac{(1 ft)^{3}}{(0.3048 m)^{3}}*\frac{0.454 kg}{1 lbm}*50 m*25 m*2 m*9.81 m/s^{2} = 2.96 \cdot 10^{7} N}*\frac{0.2248 lbf}{1 N} = 6.65\cdot 10^{6} lbf[/tex]              

Therefore, the weight of the pond is 6.65x10⁶ lbf.
