How many grams are there in 2.00 moles of copper (ii) oxide
tatuchka [14]

Answer: 159 grams

Explanation:

Copper (ii) oxide has the chemical formula CuO.

Now given that:

Mass of CuO in grams = ? (let unknown value be Z)

Number of moles = 2.00 moles

Molar mass of CuO = ?

For the molar mass of CuO: Atomic mass of Copper = 63.5g ; Oxygen = 16g

= 63.5g + 16g

= 79.5 g/mol

Apply the formula:

Number of molecules = (mass in grams/molar mass)

2.00 moles = (Z / 79.5 g/mol)

Z = 79.5 g/mol x 2.00 moles

Z = 159g

Thus, there are 159 grams in 2.00 moles of copper (ii) oxide

Give reasons that might help explain the following observations:
marin [14]

The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

<h3>What is the Grignard reagent?</h3>

The Grignard reagent is a compound that contains alkyl magnesium halide.

a) The student will be  unsuccessful to prepare a Grignard reagent from 4-bromocyclohexanol because of the -OH group that reacts with the Grignard reagent when formed.

b) The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

c) The compound (2S, 3R)- 2,3-Dibromobutane has a specific rotation, [a]D, 0⁰ because it is a meso compound.

d) This is because, the tertiary alkyl halide is more prone to elimination reaction giving the alkene.

e) This is because, the reaction may be occurring by an SN1 mechanism and the rate determining step is the formation of the carbocation.
