Answer: 1. 
2. 3 moles of 
: 2 moles of 
3. 0.33 moles of : 0.92 moles of
4. is the limiting reagent and is the excess reagent.
5. Theoretical yield of 
is 29.3 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
3 moles of require = 2 moles of
Thus 0.33 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 3 moles of give = 2 moles of
Thus 0.33 moles of give = of
Theoretical yield of 
Thus 29.3 g of aluminium chloride is formed.
Using the same anchor points, he determined the freezing temperature for water to be 0 degree and the boiling temperature 100 degrees. The Celsius scale is known as a Universal System Unit. It is used throughout science and in most countries.
Answer:
heat flow
Explanation:
heat flow moves to a higher temperature to a lower temperature
Energy is released by the formation of chemical bonds, and energy is
absorbed when the bonds are broken.
<h3>What is a chemical reaction?</h3>
A chemical reaction involves the formation of new compounds from
reactants . It involves the formation and breaking of bonds in the
elements.
Energy is released by the formation of chemical bonds and this type of
reaction is referred to as exothermic while energy is absorbed when the
bonds are broken and is referred to as an endothermic reaction.
