What happens if more product is added to a system at equilibrium

Chemistry

1 answer:

Phoenix [80]3 years ago

7 0

Answer:

More reactants will be produced

Explanation:

Le Chatelier's principle; adding additional product or reactant will move the equilibrium left or right to compensate and come back to equilibrium

By adding more product to your system at equilibrium, the equilibrium will shift towards reactants, more reactants will be produced

This pendulum is suspended on a string. The balanced forces of gravity and the tension force within the string are holding the p

GuDViN [60]

Answer:

The pendulum will begin to swing in the direction of the unbalanced force

Explanation:

The action of an unbalanced force on a pendulum will cause the pendulum to go into oscillation.

It must be stated that an unbalanced force causes acceleration of an object, in the direction of that force. Hence, unbalanced forces always set an object in motion.

A constant-volume calorimeter was calibrated by carrying out a reaction known to release 3.50 kJ of heat in 0.200 L of solution

Dmitrij [34]

Answer:

The change in internal energy is - 1.19 kJ

Explanation:

Step 1: Data given

Heat released = 3.5 kJ

Volume calorimeter = 0.200 L

Heat release results in a 7.32 °C

Temperature rise for the next experiment = 2.49 °C

Step 2: Calculate Ccalorimeter

Qcal = ccal * ΔT ⇒ 3.50 kJ = Ccal *7.32 °C

Ccal = 3.50 kJ /7.32 °C = 0.478 kJ/°C

Step 3: Calculate energy released

Qcal = 0.478 kJ/°C *2.49 °C = 1.19 kJ

Step 4: Calculate change in internal energy

ΔU = Q + W W = 0 (no expansion)

Qreac = -Qcal = - 1.19 kJ

ΔU = - 1.19 kJ

The change in internal energy is - 1.19 kJ

Based on your knowledge of intermolecular forces, which of the following would you expect to have the highest boiling point? hex

12345 [234]

Answer:
Hexanol has the highest boiling point.

Explanation:
Boiling points of all give compounds are as follow,

Hexanol   = 157 °C

Hexanal = 129 °C

Hexanone = 128 °C

Hexane =   68 °C

Types of Interactions found in these compounds are,

Hexanol   = Hydrogen Bonding & London Dispersion Forces

Hexanal   = Dipole-Dipole Interactions & London Dispersion Forces

Hexanone = Dipole-Dipole Interactions & London Dispersion       Forces

Hexane =   Only London Dispersion Forces

Strength of Intermolecular Forces:
Hydrogen forces are stronger than Dipole-Dipole Interactions, and Dipole-Dipole Interactions are stronger than London Dispersion Forces.

Result:
Hence, due to presence of strong Hydrogen Bond Interactions Hexanol has the highest Boiling Point.
