Final answer:

When the temperature of a gas rises, the average energy of the particles increases. According to the Kinetic Molecular Theory, kinetic energy is proportional to its temperature. However, a rise in temperature doesn't directly double the energy.

Explanation:

The behavior of particles in a gas is very much affected by temperature changes. When the temperature of a gas increases, so too does the energy that the gas's particles have. This is defined by the Kinetic Molecular Theory, which states that the kinetic energy of a gas is proportional to its temperature. Therefore, when the temperature of a gas rises from 23°C to 46°C, the average energy of the particles increases. However, it doesn't double as an increase in temperature is not responsible for directly doubling the energy. Additionally, this increase in energy results in an increase in the velocity of the particles, but not necessarily by a factor of sqrt(2).

Final answer:

To produce 100.0 L of NH3 at STP, 62.4 grams of N2 are required.

Explanation:

The balanced equation for the reaction is:

N2(g) + 3H2(g) → 2NH3(g)

According to the balanced equation, one mole of N2 reacts with three moles of H2 to produce two moles of NH3. From this information, we can use stoichiometry to determine the mass of N2 required to produce 100.0 L of NH3 at STP.

First, we need to convert liters of NH3 to moles using the ideal gas law and the molar volume of a gas at STP (~22.4 L/mol). Once we have the moles of NH3, we can use the mole ratio from the balanced equation to calculate the moles of N2. Finally, we can use the molar mass of N2 to convert moles to grams.

Let's calculate:

1. Convert liters of NH3 to moles of NH3: 100.0 L * (1 mol/22.4 L) = 4.46 mol NH3
2. Calculate moles of N2 using the mole ratio: 4.46 mol NH3 * (1 mol N2/2 mol NH3) = 2.23 mol N2
3. Convert moles of N2 to grams of N2 using the molar mass of N2 (28 g/mol): 2.23 mol N2 * 28 g/mol = 62.4 g N2

Therefore, 62.4 grams of N2 are required to produce 100.0 liters of NH3 at STP.

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

  Reaction equation is given as;

          C  +  O₂  →  CO₂  

In this reaction, C and O₂ are the reactants

  CO₂ is the product of the reaction.

• This reaction is called a combination reaction in which two species combines to give a product.

Explanation:

Electronegativity is the chemical property of an element. This is defined as the tendency of an atom to attract the shared pair of electrons towards itself when a bond is formed.

• This property of an atom increases as we move from left to right in a period because the number of charge on the nucleus increases.
• this property decreases as we move from top to bottom in a group because electrons get added up in the new shells which make it further far away from the nucleus.
