Which of the following are true about complex ion formation and equilibrium?
The formation constant for a complex ion is typically less than 1.
A complex ion is formed typically when a cation reacts with a lewis base.
The addition of a compatible ligand to a saturated solution a sparsely soluble compound results in an increase in solubility.

Answers

Answer 1

Among the given statements, the second and third statements are true about complex ion formation and equilibrium.

1. The formation constant for a complex ion is typically greater than 1, not less than 1. A larger formation constant indicates that the complex ion formation is more favorable.
2. A complex ion is indeed formed typically when a cation reacts with a Lewis base. The Lewis base donates electron pairs, forming a coordinate covalent bond with the cation, creating a complex ion.
3. The addition of a compatible ligand to a saturated solution of a sparsely soluble compound does result in an increase in solubility. This happens because the formation of the complex ion leads to a decrease in the concentration of the cation, which shifts the equilibrium of the sparingly soluble compound to dissolve more of it.

The second and third statements accurately describe complex ion formation and equilibrium, while the first statement is incorrect as the formation constant is typically greater than 1.

The total initial momentum of 7.0 kgm/s is 2.8 kgm/s,

This scenario describes an inelastic collision between two carts. In an inelastic collision, the total kinetic energy of the system is not conserved and some of it is converted into other forms of energy, such as heat or sound.

Using the principle of conservation of momentum, we can calculate the final velocities of the two carts after the collision. The initial momentum of the first cart is 1.0 kg * 5.0 m/s = 5.0 kgm/s. The initial momentum of the second cart is 1.0 kg * 2.0 m/s = 2.0 kgm/s. The total initial momentum of the system is 5.0 kgm/s + 2.0 kgm/s = 7.0 kg*m/s.

After the collision, the final momentum of the two carts is equal to the total initial momentum, since no external forces are acting on the system. Therefore, the final momentum of the first cart + the final momentum of the second cart = 7.0 kg*m/s.

We can use the final velocities given in the problem to solve for the final momentum of each cart.

The final momentum of the first cart is 1.0 kg * 0.50 m/s = 0.50 kgm/s

The final momentum of the second cart is 1.0 kg * 2.3 m/s = 2.3 kgm/s

And add them: 0.50 kgm/s + 2.3 kgm/s = 2.8 kgm/s, which is equal to the total initial momentum of 7.0 kgm/s.

We can also observe that the final velocity of the first cart is less than its initial velocity, while the final velocity of the second cart is greater than its initial velocity. This is expected in an inelastic collision as some of the kinetic energy of the system is converted into other forms of energy, causing the final velocities of the carts to be different from their initial velocities.

lydia picks up oranges each of which is 1kg from a basket on the ground and puts them on a table that is 1.5 meter high. how much work is she doing on each orange

Answers

Explanationnswer:



Answer:find out ;/

Explanation:

To calculate the amount of work Lydia is doing on each orange, you need to use the formula for work, which is Work = Force x Distance x Cos(theta). In this case, the force is the weight of the orange (1 kg), the distance is the height of the table (1.5 meters), and theta is the angle between the force and the distance (which is assumed to be 90 degrees, since she is lifting the orange straight up).

So the work done on each orange is 1 kg x 1.5 meters x cos(90) = 1.5 Joules.
