What is the mass of CO2 lost at 20 min from the limestone sample?

How much CO2, in moles, was lost at 20 min from the limestone sample?

How much CO3 2- was lost at 20 min from the limestone sample?

Answers

Answer:

The mass, CO2 and CO3 from the limestone sample is discussed below in details.

Explanation:

(A) mass loss of sample of limestone after 20 min

= 0.8437g-0.5979g = 0.2458 g

From the given reaction of limestone, 2 mol of the sample gives 2 moles of CO 2.

Therefore  

184.4 g ( molar mass of limestone) gives2× 44 g of carbon dioxide.

1 g of sample gives 88/184.4 g of carbon dioxide

Hence 0.2458 g sample gives

= 88/184.4 × 0.2458 g = 0.117 g carbon dioxide

(B) mole of CO 2 lost = weight/ molar mass

= 0.117 g / 44 g/mol =0.0027 mole

(C). 1 mol of limestone contain 2 mol of carbonate ion

From the reaction we know that carbonate ion of limestone is converted into carbondioxide

Hence lost carbonate ion = 0.2458 g

(D) we know that

1 mol limestone contain 1mol CaCO​​​ 3

Hence in sample present CaCO​​​ 3

= 1mole / 184.4 g × 0.8437 g= 0.00458 mol CaCO​​​3

What is the volume in liters of 222 g of neon if neon has a density of 0.900 g/L?

Answers

Answer:

[tex]V=247L[/tex]

Explanation:

Hello there!

In this case, since the density is defined as the degree of compactness of a substance and is computed by diving the mass over the volume it occupies:

[tex]\rho =\frac{m}{V}[/tex]

Given the density and the mass of the neon, we can compute its density as shown below:

[tex]V=\frac{m}{\rho} =\frac{222g}{0.900g/L}\\\\V=247L[/tex]

Best regards!

The volume of neon in liters is 246.67 L.

To calculate the volume of neon, we use the formula below.

Formula:

D = m/V............... Equation 1

Where:

D = Density of neonm = mass of neonV = Volume of neon.

make V the subject of the equation.

V = m/D............... Equation 2

From the question,

Given:

m = 222 gD = 0.900 g/L

Substitute these values into equation 2

V = 222/0.9V = 246.67 L.

Hence, The volume of neon in liters is 246.67 L.

What is represented in each block of the periodic tables?

Answers

the answer is c

One ion is represented in each block of the periodic tables. Hence option C is correct.

What is periodic table?

Periodic table is defined as a table with the chemical elements ordered by increasing atomic number, displaying the elements to show trends in their characteristics. The elements are arranged in the Periodic Table in accordance with their related chemical and physical characteristics. There are rows and columns in the table. The periodic table's vertical columns stand in for Groups. Periods are shown in the table as horizontal rows.

Ions are defined as any atom or collection of atoms that carries one or more electrical charges, either positive or negative. The positive ions are known as cation while the negative ions are known as anion. When an atom's number of protons and electrons is out of balance, ions are created.

Thus, one ion is represented in each block of the periodic tables. Hence option C is correct.

A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL

Answers

Answer:

14

Explanation:

70g/(35mL-30mL)=14g/mL

If a rock with a mass of 70 grams is dropped into a graduated cylinder with 30 milliliter of water in it. The water level rose to 35 milliliters, then the density of the rock in gram / milliliter would be  14  gram / milliliter.

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

The mass of ṭhe rock = 70 grams

The volume of the rock = 35 milliliters - 30 milliliters

                                       = 5 milliliters

The density of the rock = mass of the rock / volume of the rock

                                       =70 grams / 5 milliliters

                                       = 14  gram / milliliter

Thus, the density of the rock would be 14 gram / milliliter.

What are the signs of ΔH, ΔS, and ΔG for the spontaneous conversion of a crystalline solid into a gas?

Answers

Answer:

ΔH>0, ΔS>0, and ΔG<0

Explanation:

Crystalline solid → Gas

ΔG < 0 T  as the reaction is Spontaneous The solid is converted into gas so the Entropy will increase as randomness is more in gas than solid, ΔS > 0

using Gibbs equation

ΔG = ΔH - TΔS

as ΔG < 0 and ΔS > 0

ΔH - TΔS <0

ΔH < TΔS ⇒ΔH >0

This gives that ΔH will be Positive but it will be less than TΔS. So we need to provide some energy to convert crystalline solid into gas.

Answers

The diagram best shows the field lines around two particles with opposite charges is the third diagram. Therefore, option C is correct.

What is field line ?

A graphic tool for viewing vector fields is a field line. It is made up of a fictitious directed line that is perpendicular to the field vector over its whole length.

Among many other sorts, they are employed to display magnetic, electric, and gravitational fields. In the study of fluid mechanics, streamlines are field lines that display the velocity field of a fluid flow.

The field lines are parallel to the charge's surface. Both the size of the charge and the quantity of field lines are proportional. The positive charge is where the field lines begin, and the negative charge is where they come to a conclusion.

Thus, option C is correct.

Explanation:

According to the second law of thermodynamics, the energy of the universe is conserved but the entropy of the universe is continuously increasing.

What is the second law of thermodynamics?

The second law of thermodynamics put some restrictions on the direction of heat transfer and attainable efficiencies of heat engines. This law stated that any spontaneously happening process will lead to an escalation in the entropy (S) of the universe.

This law explains that the entropy of an isolated system will never decrease with time. Mathematically, the 2nd law of thermodynamics:

ΔS (universe) > 0

where ΔS of the universe is the change in the entropy of the universe.

The second law of thermodynamics provides the criterion for the feasibility of any physical or chemical process. A physical or chemical process cannot take place unless it must follow both the 1st and 2nd laws of thermodynamics.
