0.11 moles of Aluminium chloride
<u>Explanation:</u>
<u />
Given:
2Al + 3Cl₂ → 2AlCl₃
According to the balanced equation:
2 moles pf Aluminium form 2 moles of Aluminium chloride.
So, 1 mole of Al will form 1 mole of Aluminium chloride.
0.11 mole of Al is present.
So, 0.11 mol of Al will form 0.11 mol of Aluminium chloride.
Identify each of the following as a product or a coefficient in reaction below
<h2> 2H^+ + CO3^2- → H2O + CO2</h2><h2 /><h2 /><h3> <u><em>reactant are</em></u></h3><h2> H^+ and CO3^2-</h2>
<u><em>Reason: </em></u>Reactant of a chemical reaction are found in the left side. They are initially present in a chemical reaction which are consumed to form product.
<h3> <em><u>Product are</u></em></h3>
H2O and CO2
<u><em>Reason</em></u>: They are found in the right side of the reaction. Product are produced in a chemical reaction.
<em><u>coefficient</u></em>
<em><u> </u></em><em><u> </u></em>is 2
- Coefficient is the number found in front of a formula.
- Therefore 2 is the coefficient since it is found in front of H^+
Answer:
True
Explanation:
Theories are ideas which are used to make predictions
Answer:
B = CHCl2 + Cl2 --> CHCl3 + Cl
Explanation:
Free radical halogenation is a chlorination reaction on Alkane hydrocarbons. This involves the splitting of molecules into radicals/ unstable molecules in the presence of sunlight/ U.V light which ensures bonding of the molecules.
Free radical chlorination is divided into 3 steps which are:
The initiation step
The propagation step
The termination step
So in reference to the question, propagation step involves two steps.
The first step is where the molecule in this case the methylene chloride(CH2Cl2) loses a hydrogen atom and then bond with a chlorine atom radical to give a nethylwnw chloride radical and HCl.
The second step involves the reaction of this methylene chloride got in the first step with chlorine molecule to form trichloride methane and a chlorine radical.
You would find in the attachment the 2 step mechanism.
