The balance chemical equation is 2LiOH + CO2 → Li2CO3 + H2O. Therefore, option A is correct.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the change are both equal.

The law of conservation of mass states that when a chemical reaction takes place, the mass of the reactants and products should be equal. As a result, during the chemical process, the number of atoms in each element remains constant. The chemical equation must be balanced as a result.

The chemical equation is said to be balanced if there are no inequalities. Every element in this illustration now has the same amount of atoms on the reactant and product sides.

Thus, option A is correct.

Solution :

lt is given that in 18 mL of water their are [tex]6.022\times 10^{23}[/tex] water molecules.

We know, that 1 molecule of water contains 2 atoms of hydrogen.

Hydrogen atom in 18 mL water is,

[tex]2\times 6.022\times 10^{23} = 12.044 \times 10^{23}[/tex] .

So, number of hydrogen atoms in 1 L = 1000 mL are :

[tex]N = \dfrac{1000}{18}\times 12.044\times 10^{23}\\\\N = 6.69 \times 10^{25}\ atoms[/tex]

Hence, this is the required solution.

Explanation:

The average atomic mass will be 3.70 amu

We have to obtain the average atomic mass by multiplying the mass of each isotope in amu by the relative abundance of the given isotope as contained in the data of the question.

Hence;

Average atomic mass;

(0.30 * 4) + (0.20 * 5) + (0.50 * 3)

= 1.20 + 1.00 + 1.50

= 3.70 amu

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.

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.

Answer:

837.02 ohms

Explanation:

Step one:

Given data

Frequency= 60Hz

L1= 0.75H

L2= 1.47H

When inductors are connected in series, the total inductance is the sum of the individual inductance

Step two:

Inductor 1

[tex]Xl1= 2\pi fL\\\\Xl1= 2*3.142*60*0.75\\\\Xl1= 282.78 ohms[/tex]

Inductor 2

[tex]Xl2= 2\pi fL\\\\Xl2= 2*3.142*60*1.47\\\\Xl2= 554.24 ohms[/tex]

A chemist must prepare 550.0 mL of hydrochloric acid solution with a pH of 1.60 at [tex]25^oC[/tex]. He will do this in three steps: Fill a 550.0 mL volumetric flask about halfway with distilled water. Measure out a small volume of concentrated (8.0M) stock hydrochloric acid solution and add it to the flask. Fill the flask to the mark with distilled water. Calculate the volume of concentrated hydrochloric acid that the chemist must measure out in the second step. Round your answer to 2 significant digits.

Answer: The volume of concentrated hydrochloric acid solution is 1.7 mL.

Explanation:

To calculate the hydrogen ion concentration, we use the formula:

[tex]pH=-\log [H^+][/tex]

We are given:

pH = 1.60

Putting values in above equation, we get:

[tex]1.60=-\log [H^+][/tex]

[tex][H^+]=antilog (-1.60)[/tex]

[tex][H^+]=0.0251M[/tex]

To calculate the volume of concentrated solution, we use the equation:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1\text{ and }V_1[/tex] = molarity and volume of concentrated acid solution

[tex]M_2\text{ and }V_2[/tex] = molarity and volume of diluted acid solution

We are given:

[tex]M_1=8.0M\\V_1=?mL\\M_2=0.0251M\\V_2=550mL[/tex]

Putting values in above equation, we get:

[tex]8.0\times V_1=0.0251\times 550\\\\V_1=\frac{0.0251\times 550}{8.0}=1.7mL[/tex]

Hence, the volume of concentrated hydrochloric acid solution is 1.7 mL.

According to Avogadro's number, there are 6.926×10²⁴ representative particles in 11.5 moles of silver.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number or number of moles×Avogadro's number=11.5×6.023×10²³=6.926×10²⁴ atoms.

Thus, there are 6.926×10²⁴ representative particles in 11.5 moles of silver.

A is a Metallic Solid

Let us look again at the physical properties of metals;

Metals are

We can now see that both ductility and electrical conductivity are metallic properties.

B is a Molecular solid

Molecules are formed when atoms share electrons. In molecules, there are no free electrons hence molecules do not conduct electricity.

Secondly, molecules are held together in the solid state by weak dispersion forces hence molecular solids have a low melting point.
