Consider the equation: 2NO2(g) N2O4(g). Using ONLY the information given by the equation which of the following changes would increase the molar concentration at equilibrium of the product N2O4(g)?increase the pressure
increase the temperature
decrease the concentration of NO2(g)
decrease the temperature
decrease the pressure

Answers

Answer 1

Answer: I believe the correct answer is the first option. To increase the molar concentration of the product N2O4, you should increase the pressure of the system. You cannot determine the effect of changing the temperature since we cannot tell whether it is an endothermic or an exothermic reaction. Also, decreasing the number of NO2 would not increase the product rather it would shift the equilibrium to the left forming more reactants. The only parameter we can change would be the pressure. And, since NO2 takes up more space than the product increasing the pressure would allow the reactant to collide more forming the product.

Answer 2

Answer:

The answers A. increase the pressure

What is an ionic bond?

Answers

Ionic bond is formed when there is a transfer of electron(s) from metallic atom to non-metallic atom.

The correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons

Ionic bond exist between a metal and a nonmetal.

In this bonding, the metal losses it's valence electron to form a stable metallic ion, while the nonmetal receives the electron from the metal to form a stable nonmetallic ion which results in the formation of an ionic compound.

With the above information, we can see that ionic bond involves a transfer of electron(s).

Thus, the correct answer to the question is Option B. A bond resulting from the transfer of 1 or more electrons.

Answer: B

Explanation:

Ionic bonding is the complete transfer of electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

If the total mass of the products of a reaction is 250 g, what was the total mass of the reactants

Answers

The total mass in a reaction is always conserved . Thus the total mass of reactants will be equal to the total mass of products. Hence f the total mass of the products of a reaction is 250 g, the total mass of the reactants is also 250g.

What is law of conservation of mass ?

Mass conservation law is same as that of law of conservation of energy. That is, mass can neither be created nor be destroyed. Therefore, total mass of the system is conserved or it is a constant.

For any type of changes occurring for a substance, let it be a chemical change or physical change the total mass of the initial or original substance is gaines after the change from the new product or new state of the same substance.

Thus, no atoms created or lost in a reaction but they are regrouped to form new products. The new products are formed by bond making or bond breaking in the reactants their weight is completely transferred to the products.

Therefore, if a reaction is having total mass of 250 g in product side then it 250 g was the total mass in reactant side.

Every chemical equation must be balanced to preform the conservation of mass law, so, what ever is on the products is going to be on the reactants. The mass is not created nor destroyed.

How does a magnet separate mixtures?

Answers

It can only do that when one of the components of the mixture is a magnetic
material.

When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.

It will separate when one of the elements found in the mixture is magnetic. This process can't be done in a compound as a compound is chemically bonded!

A student rides his scooter . The student has a mass of 40.0 kg and travels with a constant acceleration of 1.5 m/s . What net force is the student experiencing ?

Answers

Answer:

60N

Explanation:

You use the equation F=AM where F=Force A=Acceleration and M=Mass

You multiply the Acceleration (1.5) and the Mass (40) together and that gives you 60N as the force
