Explanation:

An equation is said to be balanced when the number of atoms on both reactant and product side are equal in number.

Whereas an equation where electrolytes in an aqueous solution are represented as dissociated ions is known as an ionic equation.

For example, HCl(aq) + LiOH(aq) \rightarrow H_{2}O(l) + LiCl(aq) can be represented in ionic form as follows.

   H^{+} + Cl^{-} + Li^{+} + OH^{-} \rightarrow H_{2}O(l) + Li^{+} + Cl^{-}

Now, cancelling the common ions present on both sides of the equation. The resulting, ionic equation will be as follows.

                 H^{+} + OH^{-} \rightarrow H_{2}O(l)

The balanced complete ionic equation is

{{\text{H}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left( {aq}\right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{O}}{{\text{H}}^ - }\left({aq} \right)\to{{\text{H}}_2}{\text{O}}\left( l \right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)

Further Explanation:

The three types of equations that are used to represent the chemical reaction are as follows:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The reactants and products remain in <em>undissociated </em>form in the <em>molecular equation</em>. In the case of total ionic equation, all the ions that are dissociated and present in the reaction mixture are represented while in the case of net or <em>overall ionic equation</em> only the <em>useful ions</em> that participate in the reaction are represented.

The steps to write the complete or total ionic reaction are as follows:

Step 1: Write the molecular equation for the reaction with the phases in the bracket.

In the reaction, HCl reacts with LiOH to form LiCl and {{\text{H}}_{\text{2}}}{\text{O}} . The balanced molecular equation of the reaction is as follows:

{\text{HCl}}\left({aq}\right)+{\text{LiOH}}\left({aq}\right)\to{{\text{H}}_{\text{2}}}{\text{O}}\left( l \right)+{\text{LiCl}}\left( {aq}\right)

Step 2: Dissociate all the compounds with the aqueous phase to write the total ionic equation. The compounds with solid and liquid phases remain same. The total ionic equation is as follows:

{{\text{H}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{O}}{{\text{H}}^ - }\left({aq}\right)\to{{\text{H}}_2}{\text{O}}\left( l \right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)

Therefore, the complete ionic equation obtained is as follows:

{{\text{H}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{O}}{{\text{H}}^ - }\left({aq}\right)\to{{\text{H}}_2}{\text{O}}\left( l \right)+{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)

Answer:

See explanation.

Explanation:

1. Forrest: From 425,000,000 to 300,000,000 is a change of 125,000,000. Divide the 125,000,000 by 425,000,000 to get the percent change:

125,000,000 / 425,000,000 = .294, which is a 29.4% change, a decrease.

2. Population: From 4,500 to 326,500,000 is a change of 326,495,500. Divide 326,495,500 by 4,500 to get the percent change.

326,495,500 / 4,500 = 72,554.55 which is a change of 7,255,455% change, an increase.

3. Conclusion: The growth in population required living area. People needed farms, houses, cities, and communities to live in. Forests were cleared to make room for the people to live. Forests are also used to provide building materials. The population increase contributed to the decrease in forest lands.

Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those
Tanya [424]

Answer:

Q is 0.5 and K is 0.01, therefore K is less than Q.

the system will proceed in the reverse direction, thereby converting products into reactants. converting Nitric oxide to form oxygen and nitrogen.

Explanation:

Given,

N2 (g) + O2 (g) « 2 NO (g)

K = 0.01

heated temperature = 2000 ⁰C

N2 moles =0.4

O2 moles =0.1

2NO moles = 0.08

Volume of container = 1L

Q is the reaction quotient  of the equilibrium equation. it is use to determined which direction the system will move to by comparing it with the K value.

Q can be calculated by multiplication of mass of reactant divide by mass of product

Q =\frac{ [N2] *[O2}{2NO}

the mass of the chemicals are in mole, there is need to convert them to moles/litre

therefore,

for N₂ : 0.4 mole per 1L container = 0.4 mol/L = 0.4M

for O₂ : 0.1 mole per 1L container = 0.1 mol/L = 0.1M

for 2NO : 0.08mole per 1L container = 0.08 mol/L = 0.08M

Q =\frac{ [N2] *[O2}{2NO} = (0.4*0.1)/0.08 = 0.5

finally, we are going to compare the value of Q with K

Note that:

if K>Q , the reaction will proceed forward, converting reactants into product.

if K<Q , the reaction will proceed backward, converting products into reactants.

if K=Q , the system of reaction is already in equilibrium.

since, Q is 0.5 and K is 0.01, therefore K is less than Q.

the system will proceed in the reverse direction, thereby converting products into reactants. converting Nitric oxide to form oxygen and nitrogen.

Describe the appearance of the material. Include its color and state (solid or liquid). Pour ¼ cup of water into a small, clear
Alex777 [14]

<u>Answer:</u>

<em>Here the given material is taken and mixed with water.</em>

<u>Explanation:</u>

The amount of material and water taken are same. Hence if it is not soluble in water it should make a dense and flowy paste like material and if it is soluble in water it should this and thicker density of water should remain.

If the amount of water that we are taking is more than the material will float in water if it is not soluble and lighter than water or would sink if it is heavier than water.
