The amount of heat energy produced when 1 g of hydrogen and 2 g of nitrogen are reacted, is -6.61 KJ

First, we shall obtain the limiting reactant. Details below:

3H₂ + N₂ -> 2NH₃

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂

Therefore,

2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂

We can see that only 0.43 g of H₂ is needed in the reaction.

Thus, the limiting reactant is N₂

Finally, we the amount of heat energy produced. Details below:

3H₂ + N₂ -> 2NH₃ ΔH = -92.6 KJ

From the balanced equation above,

When 28 grams of N₂ reacted, -92.6 KJ of heat energy were produced.

Therefore,

When 2 grams of N₂ will react to produce = (2 × -92.6) / 28 = -6.61 KJ

Thus the heat energy produced from the reaction is -6.61 KJ

when a chemical change is complete the reactant before the chemical reaction and the product after the chemical reactant will weigh same.

According to the law of mass of conservation : the mass in the chemical reaction is neither be created nor be destroyed. This means the the total mass of the reactant before the chemical reaction and the mass of the product after the reaction is same. we can say that atoms in the reactant side is equal to the atoms in the product side.

Thus, when a chemical change is complete the reactant before the chemical reaction and the product after the chemical reactant will weigh same.

Answer: The particles can move apart only if they have enough kinetic energy to overcome this force of attraction. If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid. What is particle kinetic energy? Kinetic energy is energy that an object has because of its motion. The Kinetic Molecular Theory explains the forces between molecules and the energy that they possess.

The volume in mL of 0.100 M \(HClO_3\) required to neutralize 40.0 mL of 0.230 M KOH would be 92 mL.

The equation of the reaction would be as follows:

\(KOH + HClO_3 -- > KClO_3 + H_2O\)

The mole ratio of KOH and \(HClO_3\) is 1:1.

Recall that: mole = molarity x volume.

Thus, 40.0 mL, 0.230 M KOH would be equivalent to:

40/1000 x 0.230 = 0.0092 mol KOH

From the 1:1 mole ratio, the equivalent mole of \(HClO_3\) will also be 0.0092 mol.

Since: mole = molarity x volume, then: volume = mole/molarity.

The molarity of the \(HClO_3\) is 0.100 M, thus, the volume would be:

Volume = 0.0092/0.100

             = 0.092 L

In milliliters, 0.092 = 0.092 x 1000 = 92 mL

In other words, the volume of  \(HClO_3\) required is 92 mL.

The largest effect on the population of trout in Wisconsin was caused by the introduction of non-native species into the ecosystem.

The introduction of non-native species into an ecosystem can cause a disruption in the food chain, leading to a decrease in the population of native species. In Wisconsin, the introduction of non-native species such as the brown trout and rainbow trout has had a significant impact on the population of native brook trout.

The non-native species compete with the native brook trout for food and habitat, which has led to a decrease in the brook trout population. This highlights the importance of preserving the natural balance of ecosystems and avoiding the introduction of non-native species.

To plot the calibration curve, you need to prepare iron solutions with known concentrations and measure their absorbance. You need to pipet 0 mL of the diluted solution to have 0.00 mg of iron.

In spectrophotometry, to plot the calibration curve, you need to prepare solutions with known concentrations and measure their absorbance.

We have a standard iron solution with a concentration of 0.2500g/L of pure iron (C₁). We pipet 25.00mL (V₁) of this standard iron solution into a 500mL (V₂) volumetric flask and dilute up to the mark with distilled water.

We can calculate the concentration of the diluted solution (C₂) using the dilution rule.

\(C_1 \times V_1 = C_2 \times V_2\\\\C_2 = \frac{C_1 \times V_1}{V_2} = \frac{0.2500 g/L \times 25.00 mL}{500 mL} = 0.0125 g/L\)

Then, if we wanted to prepare the blank, that is, the solution that contains the same matrix but not the analyte, and whose concentration in iron is 0.00 mg/L, we wouldn't pipet any of the diluted solution.

Answer:.The ratio PV/nRT < 1 for one mole of a real gas because of repulsive interactions between the molecules.

Explanation:

The expression PV/nRT is referred to as the compressibility factor commonly designated as Z.

This compressibility factor (Z) for real gas is often less than 1. Z<1 means attraction forces are dominant in the system.

Hence, Z<1 implies attractive and not repulsive force dominance in the system.

A conjugate base is any compound, of general formula Xn+, which can be transformed into a conjugate acid by the gain of a proton.

In other words, a conjugate base is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion.

The conjugate base is formed from the acid by losing a proton (H+).

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
