The net ionic equation for the reaction between potassium sulfide and magnesium iodide is S2- + Mg2+ -> MgS, as the potassium and iodide ions are spectator ions and do not participate in the reaction.

To determine the net ionic equation for the reaction between potassium sulfide (K2S) and magnesium iodide (MgI2), we first need to identify the ions present in each compound and then determine the products formed when they react.

Potassium sulfide (K2S) dissociates into two potassium ions (K+) and one sulfide ion (S2-):

K2S -> 2K+ + S2-

Magnesium iodide (MgI2) dissociates into one magnesium ion (Mg2+) and two iodide ions (I-):

MgI2 -> Mg2+ + 2I-

Now, we need to determine the possible products when these ions combine. Since potassium (K+) has a +1 charge and iodide (I-) has a -1 charge, they can combine to form potassium iodide (KI):

K+ + I- -> KI

Similarly, magnesium (Mg2+) and sulfide (S2-) can combine to form magnesium sulfide (MgS):

Mg2+ + S2- -> MgS

Now, we can write the complete ionic equation by representing all the ions present before and after the reaction:

2K+ + S2- + Mg2+ + 2I- -> 2KI + MgS

To obtain the net ionic equation, we remove the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the actual reaction. In this case, the spectator ions are the potassium ions (K+) and the iodide ions (I-).

Thus, the net ionic equation for the reaction between potassium sulfide and magnesium iodide is:

S2- + Mg2+ -> MgS

Answer:

Explanation:

1.1 we have to find mass of Na3PO4;

for that we have to Calculate the moles of Na3PO4 needed:

volume is 100mL = 0.1L

Molar concentration = Moles of solute / Volume of solution in L

0.1 mol/L = Moles of Na3PO4 / 0.1 L

Moles of Na3PO4 = 0.1 mol/L * 0.1 L

Moles of Na3PO4 = 0.01 mol

Now, Calculate the mass of Na3PO4 needed:

so, Mass = Moles of Na3PO4 * Molar mass of Na3PO4

Mass = 0.01 mol * 164 g/mol

Mass = 1.64 g of Na3PO4.

At pOH value  of 6.0 the pH value of the following solution is 8.0 and the concentration of [\(H^{+}\) ] ion is \(10^{-8}\)

In this question we will apply the formula

      pH +pOH = 14 . . . . . . . . . . . . .(1)

where pH = concentration of [\(H^{+}\) ] ion

pOH = concentration of [\(OH^{-}\) ] ion

As per the question

pOH =6.0

Putting the value of pOH in equation (1) we get the value of pH

              pH + 6.0 =14

             pH = 14 -6.0

             pH  = 8.0

 The value of pH if the pOH value is 6.0 is 8.0

To find the concentration of \(H^{+}\) ion we will use the following formula

This is calculated by the formula

                                 [\(H^{+}\)} = \(10^{-pH}\)

where we will write the values of pH

Hence the concentration of [\(H^{+}\)} ion is \(10^{-8}\)

Answer:

Joints

Explanation:

Without joints we would not be able to bend our arms or legs. Hence option C is correct.

Bending is defined as the behavior of a thin structural element under an external load that is applied perpendicular to the element's longitudinal axis. Plants and their parts are thought to bend as a result of a flexure process in which the curvature of the plant part changes. The plant organs' collenchyma gives them flexibility and elasticity, preventing them from breaking when bent.

The force required to bend, straighten, and support joints is applied by muscles to the bones. Muscles act in pairs of flexors and extensors because they may pull on bones but not put them back into place. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.

Thus, without joints we would not be able to bend our arms or legs. Hence option C is correct.

The lattice energy of MX is 459.2 kJ/mol.

The lattice energy (ΔH° lattice) of an ionic compound is the energy released when one mole of the solid is formed from its constituent gaseous ions under standard conditions. The lattice energy is calculated using the Born-Haber cycle, which involves several steps including atomization, ionization, dissociation, and sublimation energies.

The lattice energy is related to the Coulombic attraction between the oppositely charged ions in the solid. To calculate the lattice energy for MX, we can use the following equation:

ΔH° lattice = ΔH° sub + ΔH° ion + ΔH° diss + ΔH° formation

where ΔH° sub is the sublimation energy of M(s), ΔH° ion is the first ionization energy of M(g), ΔH° diss is the dissociation energy of X2(g), and ΔH° formation is the enthalpy of formation of MX(s).

Using the given data, we can calculate each of these values and substitute them into the equation to obtain the lattice energy. The final answer should be in units of kJ/mol.

ΔH° sub (M) = 107.3 kJ/mol

ΔH° ion (M) = 577.5 kJ/mol

ΔH° diss (X2) = 242 kJ/mol

ΔH° formation (MX) = -467.6 kJ/mol

ΔH° lattice = 107.3 + 577.5 + 242 + (-467.6) = 459.2 kJ/mol

As a result, MX has a lattice energy of 459.2 kJ/mol.

At equilibrium, the number of moles of Cl2(g) present is approximately 347.37 mol.

To determine the number of moles of Cl2(g) at equilibrium, we need to use the given equilibrium constant (Kc) and set up an ICE table to track the changes in the reactants and products.

The balanced equation for the reaction is:

CO(g) + Cl2(g) ⇌ COCl2(g)

Let's set up the ICE table:

  CO(g)     +     Cl2(g)     ⇌     COCl2(g)

Initial: 0.3500 0.05500 0

Change: -x -x +x

Equilibrium: 0.3500 - x 0.05500 - x x

Using the equilibrium concentrations in the ICE table, we can write the expression for the equilibrium constant (Kc) as:

Kc = [COCl2(g)] / [CO(g)][Cl2(g)]

Substituting the values into the equation, we have:

1.2 × 10^3 = (0.05500 - x) / [(0.3500 - x)(0.05500 - x)]

Simplifying the equation, we can cross-multiply and rearrange:

1.2 × 10^3 × (0.3500 - x)(0.05500 - x) = 0.05500 - x

Expanding and rearranging, we get:

0 = (1.2 × 10^3 × 0.05500 - 1.2 × 10^3x + 0.05500x) - x

Simplifying further:

0 = 66 - 1.245x + 0.05500x - x

0 = 66 - 0.19x

0.19x = 66

x = 66 / 0.19

Answer:

Explanation:

Divide by Avogadro's number

When molecules collide, there is generally a delay before an explosion occurs, if an explosion occurs at all. This is because an explosion requires a chemical reaction to take place, which involves the breaking of chemical bonds and the formation of new bonds. These reactions require a certain amount of energy, which is called the activation energy.

The collision of molecules can provide energy to the system, but it is not always enough to overcome the activation energy needed for a chemical reaction to occur. If the energy of the collision is less than the activation energy, no reaction will occur and there will be no explosion. If the energy of the collision is equal to or greater than the activation energy, a chemical reaction may occur and an explosion may result.

The time delay between the collision of molecules and an explosion occurring depends on the nature of the molecules and the conditions under which the collision occurs. Some chemical reactions are very fast and can occur almost instantly, while others may take longer to reach the activation energy and proceed to completion.

It's worth noting that not all collisions between molecules result in an explosion. In many cases, the collision may simply transfer energy from one molecule to another without leading to a chemical reaction.

One molecule of propanol contains only one -OH group and not three -OH groups or three -CH3 groups.

The -OH group is attached to the central carbon atom and makes propanol a useful solvent and intermediate in organic chemistry.Propanol is a colorless liquid that belongs to the family of alcohols. It has the formula C3H8O, and it contains three carbon atoms, eight hydrogen atoms, and one hydroxyl group (-OH) attached to one of the carbons. One molecule of propanol contains only one -OH group, which is attached to the central carbon atom.

Thus, option (2) is the correct answer, and the other options are incorrect.The -OH group in propanol is responsible for its unique chemical and physical properties. It makes propanol soluble in water and other polar solvents and gives it a high boiling point of around 97°C. The hydroxyl group can also participate in chemical reactions, such as esterification, dehydration, oxidation, and reduction. For example, propanol can be oxidized to form propanal and then propanoic acid, which is a useful synthetic intermediate for many organic compounds.Apart from the -OH group, propanol also contains two other functional groups called methyl groups (-CH3). These are attached to the two carbon atoms adjacent to the central carbon. However, the question only asks about the number of -OH groups in propanol, so the methyl groups are irrelevant.

The decomposition of aspirin (acetylsalicylic acid, \(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)).

Explanation:

(a) From the question,

According to Avogadro's Law,

1 mole of every gas at STP occupies a volume of 22.4 dm³

But mass of 1 mole of the diatomic gas  = molar mass of the gas.

This Implies that,

The molar mass of the gas at STP occupies a volume of 22.4 dm³

From the question,

If,

0.25 L bottle contain 1.76 g of the gas,

Therefore,

Molar mass of the gas = (1.76×22.4)/0.25

Molar mass of the gas = 157.7 g.

(b) Density of the gas = mass/volume

D = m/v

Given: m = 1.76 g, v = 0.25 L = 0.25 dm³

Therefore,

D = 1.76/0,25

D = 7.04 g/dm³
