Balance the equation for the reaction of benzene and hydrogen to form cyclohexane.. C6H6 + H2 → C6H12.
Vedmedyk [2.9K]
Here is a universal law to balance chemical equations :
All chemical equations must be balanced because of the law of conservation of mass.
It states that "matter cannot be created or destroyed."
So, the number of atoms that you start with at the beginning of the reaction must equal the number of atoms that you end up with.
 keeping this law in our mind,lets balance the<span> equation for the reaction of benzene and hydrogen to form cyclohexane.

Determine the number of moles in each substance.
olchik [2.2K]

Answer:

a) 5.4 * 10^-4 moles

b) 8.2 moles

c) 0.26 moles

d) 20.76 moles

Explanation:

a)Since 1 mole of a substance has 6.02 * 10^23 atoms

x moles is present in  3.25 x 1020 atoms of lead

3.25 x 1020 atoms of lead/6.02 * 10^23 atoms = 5.4 * 10^-4 moles

b) Since 1 mole of a substance has 6.02 * 10^23 molecules

x moles is present in  4.96 x 1024 molecules of glucose

x = 4.96 x 1024 molecules of glucose/6.02 * 10^23 molecules = 8.2 moles

c) Since 1 mole of a substance has 6.02 * 10^23 formula units

x moles is present in 1.56 x 1023 formula units of sodium hydroxide

x =  1.56 x 1023 formula units /6.02 * 10^23 = 0.26 moles

d) Since 1 mole of a substance has 6.02 * 10^23 ions

x moles is present in 1.25 x 1025 copper(ll) ions

x = 1.25 x 1025 copper(ll) ions/6.02 * 10^23 ions = 20.76 moles
