Explanation:

For a chemical system in a state of dynamic equilibrium, the rate of forward reaction is equal to the rate of reverse reaction.

For this system under consideration;

I2(s)⇄I2(g)

When we heat the container, solid iodine is converted into purple coloured iodine vapour.

When equilibrium is achieved in the system, there will be no net change in the amount of solid iodine and iodine vapour present in the system since the rate of forward and reverse reactions are equal for a system in a state of equilibrium.

Answer:

No-till conservation tillage

Explanation:

No till conservation involves the soil not being touched which gives rise to a large amount of organic matter being left on the surface.

The Advantage of this method is that it helps to prevent erosion such as that of wind and water due to the little or no exposure of the soil surface and helps to provide nutrients to the plants through the organic matter present.

The Disadvantage of this method is its heavy reliance of chemicals such as herbicides in killing the weeds in order to prevent competition for vital compounds with the main plants.

The volume of a substance when given the density and mass can be found by using the formula

\(volume = \frac{mass}{density} \\\)

From the question

mass = 4500 g

density = 20.5 g/cm³

We have

\(volume = \frac{4500 }{20.5} \\ = 219.51219...\)

The molarity of the solution is approximately 0.00174 M.  To calculate the molarity of a solution, we need to know the mass of the solute (NaCl) and the volume of the solution.

Given:

Mass percent of NaCl in the solution = 0.92%

Volume of the solution = 90.0 mL

Step 1: Convert the mass percent to grams of NaCl.

Assuming 100 g of the solution, 0.92% of that would be NaCl:

0.92 g NaCl = 0.0092 g NaCl

Step 2: Convert the mass of NaCl to moles.

We can use the molar mass of NaCl to convert the mass to moles.

Molar mass of NaCl = 22.99 g/mol (sodium) + 35.45 g/mol (chlorine) = 58.44 g/mol

moles of NaCl = 0.0092 g NaCl / 58.44 g/mol = 0.000157 mol NaCl

Step 3: Convert the volume of the solution to liters.

Since the volume was given in milliliters, we need to convert it to liters.

90.0 mL = 90.0 mL * (1 L / 1000 mL) = 0.090 L

Step 4: Calculate the molarity.

Molarity (M) = moles of solute / volume of solution in liters

M = 0.000157 mol NaCl / 0.090 L = 0.00174 M

Therefore, the molarity of the solution is approximately 0.00174 M.

Answer:

Minerals can form in three primary ways being precipitation, crystallization from a magma and solid- state transformation by chemical reactions (metamorphism). Mineral Precipitation is when a mineral is formed by crystallization from a solution. Examples include quartz, halite (table salt), calcite, and gypsum.

Answer:

When magma cools slowly, deep below the surface, it has time to form large crystals in regular patterns. The second way that minerals form is through solutions. (A solution is when one substance is dissolved uniformly in a liquid.) When elements and compounds leave the solution, they can crystalize.

Explanation:

The moles of sulfur needed would be 0.7.

From the equation of the reaction, the mole ratio of Al to S8 is 16:3, meaning that for every 16 moles of Al, 3 moles of S8 would be required.

Thus, if 3.75 moles of Al react, the mole of S8 that would be required can be calculated as:

                                    = 3 x 3.75/16

                                     = 0.7 moles

The amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

To calculate the molarity of Kool Aid desired, we need to determine the number of moles of Kool Aid powder and sugar in the package. Since the molecular formula for sugar is C12H22O11, we can calculate its molar mass as follows:

Molar mass of C12H22O11 = (12 * 12.01) + (22 * 1.01) + (11 * 16.00)

= 144.12 + 22.22 + 176.00

= 342.34 g/mol

Given that the package contains 4.25 grams of Kool Aid powder, we can calculate the number of moles of Kool Aid powder using its molar mass:

Number of moles of Kool Aid powder = Mass / Molar mass

= 4.25 g / 342.34 g/mol

≈ 0.0124 mol

Similarly, for the sugar, which has a molar mass of 342.34 g/mol, we can calculate the number of moles of sugar using its mass:

Number of moles of sugar = Mass / Molar mass

= 192.00 g / 342.34 g/mol

≈ 0.5612 mol

Now, to calculate the molarity of the desired Kool Aid solution, we need to determine the volume of water. Given that 1.06 quarts is equal to 1 liter, and we have 2.00 quarts of water, we can convert it to liters as follows:

Volume of water = 2.00 quarts * (1.06 liters / 1 quart)

= 2.12 liters

To find the molarity, we use the formula:

Molarity (M) = Number of moles / Volume (in liters)

Molarity of Kool Aid desired = (0.0124 mol + 0.5612 mol) / 2.12 L

≈ 0.286 M

To prepare 65 mL of the desired molarity, we can use dilution calculations. We need to determine the volume of concentrated solution and the volume of water needed.

Let's assume the concentration of the concentrated Kool Aid solution is C M. Using the dilution formula:

(C1)(V1) = (C2)(V2)where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Given that C1 = C M and V1 = V mL, and we want to prepare a final volume of 65 mL (V2 = 65 mL) with a final concentration of 0.286 M (C2 = 0.286 M), we can rearrange the formula to solve for the volume of the concentrated solution:

(C M)(V mL) = (0.286 M)(65 mL)

V mL = (0.286 M)(65 mL) / C M

So, the amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

Explanation:

An endothermic reaction refers to a reaction in which heat taken in. This implies that heat is usually absorbed by the reaction system. The enthalpy of reaction for an endothermic reaction is always positive.

The triple bond between two Nitrogen atoms in N2 gas is very strong due to its small size and the triple bond thus the nitrogen molecule has a high dissociation energy. This accounts for the large amount of energy required to break the triple bond between nitrogen atoms in the nitrogen molecule. This causes the oxidation of Nitrogen molecule to NO to be largely endothermic.
