Hello there!
In this case, when referring to single replacement reactions, it is crucial for us to figure out the formula of the starting reactants; thus, we know zinc is Zn and lead (IV) chloride is PbCl₄. In such a way, the reaction proceeds as follows:
Which must be balanced as shown below:
Regards!

-Two
3. In the decomposition of water, why is twice as much hydrogen as oxygen formed?
- There are two atoms of hydrogen and one atom of oxygen in a water molecule.
4. Which component is transferred between substances in an oxygen-reduction reaction?

1. In 1687 following 18 months of intense and effectively nonstop work
2.Hooke
3.Halley
4. Halley urged newton to write Principia mathematica and when the Royal society declined to pay the cost of publishing Halley paid for it out of his own pocket
5.Through using a telescope Galileo Galilei was able to prove the theories of sciences Isaac newton
6. He believe that the speed of an object motion is proportional to the force being applied and inversely proportional to the density of the medium he reason that the object moving in a void would move in definitely fast and thus any and all objects
7. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Answer:
Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.
Explanation:
The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.
At this stage the change in concentration of reactants becomes equal to the change in concentration of products.
The reaction will never cease.
That is the reason chemical equilibrium is called dynamic equilibrium.
So, forward and backward reactions will be taking place continuously at equal rates.
