Based on the available resources and profit per unit, producing 266 units of Product 1 would result in the highest total profit of BD 585.20.

To determine the maximum number of units of each product that can be produced given the available resources, we need to compare the resource requirements of the products with the available resources.

Let's calculate the resource requirements for each product:

Product 1:

- Metal sheet: 0.250 m2 per unit

- Glass sheet: 0.120 m2 per unit

- Electrical components: 3 units per unit

Product 2:

- Metal sheet: 0.150 m2 per unit

- Glass sheet: 0.050 m2 per unit

- Electrical components: 2 units per unit

Now let's compare the resource requirements with the available resources:

Metal sheets:

- Product 1 requires 0.250 m2 per unit, so the maximum number of units that can be produced using available metal sheets is 90 m2 / 0.250 m2 = 360 units.

- Product 2 requires 0.150 m2 per unit, so the maximum number of units that can be produced using available metal sheets is 90 m2 / 0.150 m2 = 600 units.

Glass sheets:

- Product 1 requires 0.120 m2 per unit, so the maximum number of units that can be produced using available glass sheets is 30 m2 / 0.120 m2 = 250 units.

- Product 2 requires 0.050 m2 per unit, so the maximum number of units that can be produced using available glass sheets is 30 m2 / 0.050 m2 = 600 units.

Electrical components:

- Product 1 requires 3 units per unit, so the maximum number of units that can be produced using available electrical components is 800 units / 3 units = 266 units.

- Product 2 requires 2 units per unit, so the maximum number of units that can be produced using available electrical components is 800 units / 2 units = 400 units.

Now let's determine the maximum number of units that can be produced for each product based on the limiting resource:

Metal sheets: The maximum number of units that can be produced is 360 units (for Product 1) since it requires a larger area of metal sheets.

Glass sheets: The maximum number of units that can be produced is 250 units (for Product 1) since it requires a larger area of glass sheets.

Electrical components: The maximum number of units that can be produced is 266 units (for Product 1) since it requires a larger number of electrical components.

Since the limiting resource for all three resources is reached with Product 1, the maximum number of units that can be produced for Product 1 is 266 units. As for Product 2, it can be produced up to a maximum of 250 units.

Now let's calculate the profit for each product:

Profit per unit for Product 1: BD 2.200

Profit per unit for Product 2: BD 1.400

Total profit for Product 1: 266 units × BD 2.200 = BD 585.20

Total profit for Product 2: 250 units × BD 1.400 = BD 350.00

When distilling a mixture of compounds, the boiling points of the individual compounds determine their order of distillation. Compounds with lower boiling points will vaporize and condense back into a liquid state at lower temperatures compared to compounds with higher boiling points.

In the given list of compounds, compound c, CH3CH2CH2CH2-OH, is an alcohol known as butanol. Alcohols generally have lower boiling points compared to other compounds listed. This is because alcohols exhibit intermolecular hydrogen bonding, which weakens the attractive forces between molecules and makes it easier for them to escape as vapor.

The other compounds in the list are:

a. CH3CH2CH2CH2-Cl: This is a chlorinated alkane. Chlorinated compounds typically have higher boiling points than their corresponding hydrocarbons due to the polarity introduced by the chlorine atom.

b. CH3CH2CH2CH2-NH2: This is an amine known as butylamine. Amines generally have higher boiling points compared to hydrocarbons due to intermolecular hydrogen bonding.

The reaction referred to here is the synthesis of methyl bromide (CH3Br) from methane (CH4) and hydrobromic acid (HBr):CH4 + HBr ⇌ CH3Br + H2

1. Increasing temperature: According to Le Chatelier's principle, increasing the temperature of an exothermic reaction shifts the equilibrium position in the direction that consumes heat. In this case, the forward reaction is exothermic, so an increase in temperature would shift the equilibrium position to the left, favoring the reverse reaction, and decreasing the yield of CH3Br.

2. Increasing pressure: Changing the pressure of a reaction mixture can affect the equilibrium position of a reaction only if the reaction involves a change in the number of moles of gas. In this reaction, the number of moles of gas is constant before and after the reaction, so changing the pressure would have no effect on the equilibrium position.

3. Decreasing the concentration of hydrobromic acid (HBr): Decreasing the concentration of a reactant in a reaction shifts the equilibrium position in the direction that replenishes the lost reactant. In this case, decreasing the concentration of HBr would shift the equilibrium position to the left, favouring the reverse reaction, and decreasing the yield of CH3Br.

4. Increasing the concentration of methane (CH4): Increasing the concentration of a reactant in a reaction shifts the equilibrium position in the direction that consumes the added reactant. In this case, increasing the concentration of CH4 would shift the equilibrium position to the right, favoring the forward reaction, and increasing the yield of CH3Br.

5. Adding a catalyst: A catalyst increases the rate of both the forward and reverse reactions, but it does not affect the position of the equilibrium. Therefore, adding a catalyst would increase the rate at which CH3Br is produced but would not affect the yield of CH3Br at equilibrium.

Explanation:

Based on the information provided, the rate law for the reaction 2NO(g) + 2H2(g) → N2(g) + 2H2O(g) can be written as:
Rate = k[NO]^2[H2]^1
Here, k is the rate constant, [NO] represents the concentration of NO, and [H2] represents the concentration of H2. The reaction is first order with respect to H2 and second order with respect to NO.

The rate law for this reaction can be written as follows:
Rate = k[NO]^2[H2]
Here, k represents the rate constant of the reaction and [NO] and [H2] represent the concentrations of nitrogen oxide and hydrogen gas, respectively. This rate law indicates that the rate of the reaction is directly proportional to the square of the concentration of NO and first order with respect to the concentration of H2. In other words, if the concentration of NO is doubled, the rate of the reaction will increase by a factor of 4, whereas if the concentration of H2 is doubled, the rate will increase by a factor of 2. Therefore, this reaction is first order in H2 and second order in NO.

The main reservoirs of the carbon cycle are the atmosphere, oceans, land (including vegetation and soils), and fossil fuels. In these reservoirs, carbon exists in both inorganic and organic forms.

The inorganic carbon cycle involves the exchange of carbon dioxide (CO2) between the atmosphere and oceans through processes like photosynthesis and respiration.

Organic carbon, on the other hand, is found in living organisms, dead organic matter, and soil organic matter. It is cycled through processes such as decomposition and consumption by organisms. The interactions between the inorganic and organic carbon cycles occur primarily in the biosphere, where photosynthesis converts inorganic carbon into organic carbon compounds. While inorganic carbon is primarily in the form of CO2, organic carbon is present in complex organic molecules. Both forms of carbon play crucial roles in energy transfer, nutrient cycling, and climate regulation.

The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules

Explanation:

As we know

Amount of heat gained

Q = mc (T2-T1)

Here,

mass of water in cup 2 (m) = 79.10 grams

Temperature of water in cup 2 = 16.8 degree Celsius

Specific heat of water (c) = 4.186 J/(g °C)

Final Temperature of water in cup 2  = 23.2 degree Celsius

Substituting the given values, we get -

Q = 79.10 * 4.186 * (23.2 -16.8) = 2119.121 Joules

The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules

Explanation:

Answer:

29.9 g of CO₂ will be produced by the reaction.

Explanation:

This is the reaction:

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

First of all, we state the moles of each reactant:

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

The solid salt is the limiting reactant. Ratio is 2:1

2 moles of acid can react to 1 mol of salt

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

As we only have 0.680 moles of salt, we do not have enough.

Let's work at the product side. Ratio is 1:1

1 mo of salt can produce 1 mol of gas

0.680 moles will produce 0.680 moles of gas

We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂

The number of grams of Co2 should be produced is 29.9 g.

Since

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

So,

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

Now the ratio should be 2:1 for the solid salt

And, there is 2 moles of acid can react to 1 mol of salt

So,

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

Now the product side the ratio is 1:1

So, that means

1 mo of salt can produce 1 mol of gas

So, the no of grams should be
