What Type Of Molecule Are These And What Is The Strongest IMFs In Between?

Answers

Answer 1

Answer:

CH2O is formaldehyde a covalent compound and its intermolecular forces are week

KCl is an ionic compound formed by electrostatic force of attraction between positive and negative charge. Ionic compounds also exists in three dimensional crystal lattic that is why intermolecular forces in KCl is stronger.

Moreover melting point of KCl is higher than CH2O

Find the volume, in Liters, of 2.5 x 1024 molecules of chlorine gas at STP.

Answers

Answer:

V = 93.0 L

Explanation:

Hello!

In this case, when computing the PVT properties for an ideal gas, we need to use the following equation:

[tex]PV=nRT[/tex]

In such a way, for 2.5 x 10²⁴ molecules of chlorine at STP (273.15 K and 1.00 atm) we first need the moles based on the Avogadro's number:

[tex]n = 2.5x10^{24}molec*\frac{1mol}{6.022x10^{23}molec} = 4.15mol[/tex]

Now, we solve for volume on the ideal gas equation to obtain:

[tex]V=\frac{nRT}{P}[/tex]

So we plug in and get:

[tex]V=\frac{4.15mol**0.08206\frac{atm*L}{mol*K}*273.15K}{1.00atm}\\\\V=93.0L[/tex]

Which has a bigger surface area, powder or marble chips

Answers

Answer:

powder

Explanation:

Between the powder and marble chips, the powder will have a larger surface area.

For the same masses of a solid substance in different forms such as lump, granules or powder, the smaller particle size of each form the larger the surface area.

Surface area increases from lumps to granules and them powder

A powder has the largest surface area and hence undergoes a more faster chemical reaction.

The compound cobalt(II) bromide is a strong electrolyte. Write the transformation that occurs when solid cobalt(II) bromide dissolved in water. Be sure to specify states such as (aq) or (s).

Answers

Answer and Explanation:

The chemical formula for cobalt(II) bromide is CoBr₂. As it is a strong electrolyte, it dissociates into ions when dissolved in water, according to the following chemical equation:

CoBr₂(s) → Co²⁺(aq) + 2 Br⁻(aq)

Thus, the compound CoBr₂ dissociates in water producing 1 mole of cobalt(II) ions (Co²⁺) and 2 moles of bromide ions (Br⁻) per mole of CoBr₂. The ions are dissolved in water, so they are in the aqueous state (aq).

of the following is a possible molecular formula?
D
CLE

Answers

Answer: The possible molecular formula will be [tex]CO_2[/tex]

Explanation:

Mass of C= 27.3 g

Mass of O = 72.7 g

Step 1 : convert given masses into moles.

Moles of C =[tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{27.3g}{12g/mole}=2.275moles[/tex]

Moles of O =[tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{72.7g}{16g/mole}=4.544moles[/tex]

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = [tex]\frac{2.275}{2.275}=1[/tex]

For O =[tex]\frac{4.544}{2.275}=2[/tex]

The ratio of C : O = 1: 2

Hence the empirical formula is [tex]CO_2[/tex]

The possible molecular formula will be=[tex]n\times CO_2[/tex]

C. 96,657 Pa, 966 millibar, 725 Torr

D.100.000 Pa, 760 millibar. 725 Torr

Answers

Answer:

C. 96,657 Pa, 966 millibar, 725 Torr

Explanation:

The pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.

What is pressure?

Pressure is defined as the force that is applied perpendicularly to an object's surface in relation to the area that it is dispersed over. Pressure can actually be a very good thing. Stress only occurs and has a fully negative impact when it continues to grow and that sensation of serenity and order is replaced with one of being out of control.

Given pressure = 725 mmHg

1 mmHg = 133.32 Pa

725 mmHg = 133.32 x 725 Pa

                  = 96,657 Pa

1 mmHg = 1.333 millibar

725 mmHg = 725 x 1.333 millibar

                   = 966 millibar

1 mmHg = 1 torr

725 mmHg = 725 Torr

Thus, the pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.

Number of particles inside a sugar bowl = 4.4 x 10²³

Further explanation

Given

The molar mass of sugar = 342.3 g/mol

mass of sugar = 250 g

Required

Number of particles

Solution

1 mol = 6.02 x 10²³ particles

mol of sugar :

[tex]\tt mol=\dfrac{mass}{molar~mass}[/tex]

mol = 250 g : 342.3 g/mol = 0.73 mol

How many moles of Aluminum are produced when34.2 g of alumina are broken down through the process of electrolysis

Answers

Answer:

0.670 mol

Explanation:

Step 1: Write the balanced reaction for the decomposition of alumina

2 Al₂O₃ ⇒ 4 Al + 3 O₂

Step 2: Calculate the moles corresponding to 34.2 g of Al₂O₃

The molar mass of Al₂O₃ is 101.96 g/mol.

34.2 g × 1 mol/101.96 g = 0.335 mol

Step 3: Calculate the moles of Al produced from 0.335 moles of Al₂O₃

The molar ratio of Al₂O₃ to Al is 2:4.

0.335 mol Al₂O₃ × (4 mol Al/2 mol Al₂O₃) = 0.670 mol Al

A sample of hydrate sodium carbonate has a mass of 71.5 g. after heating, the anhydrous sodium carbonate has a mass of 26.5 grams. Calculate the % water.

Answers

Answer:

62.9%

Explanation:

Step 1: Given data

Mass of hydrate sodium carbonate (mNa₂CO₃.xH₂O): 71.5 gMass of anhydrous sodium carbonate (mNa₂CO₃): 26.5 g

Step 2: Calculate the mass lost of water

We will use the following expression.

mH₂O = mNa₂CO₃.xH₂O - mNa₂CO₃

mH₂O = 71.5 g - 26.5 g = 45.0 g

Step 3: Calculate the percent of water in the hydrate sodium carbonate

We will use the following expression.

%H₂O = mH₂O / mNa₂CO₃.xH₂O × 100%

%H₂O = 45.0 g / 71.5 g × 100%

%H₂O = 62.9%

Which of the following is the conjugate base of HSO3-?
A. H2SO3
B. SO2
C. S032
D. HSO3+

Answers

Answer is C because a conjugate base is when an acid loses a hydrogen ion

An acid and a base which differ from each other by a proton are said to form a conjugate pair. The conjugate base of HSO₃⁻ is SO₃²⁻. The correct option is C.

What is a conjugate base?

The entity produced when an acid gives up a proton has a tendency to regain the proton and hence it behaves as a base. It is called the conjugate base of the parent acid.

The entity produced when a base accepts a proton has a tendency to donate the proton and hence behaves as an acid. It is called the conjugate acid of the parent base.

Sulfur dioxide dissolved in water gives sulfurous acid H₂SO₃. The conjugate base of this material contains one proton less i.e, HSO₃⁻ and the conjugate base of the substance bisulfite is SO₃²⁻which is sulfite ion.

Thus the correct option is C.
