PLEASE HURRY 1. Aluminum oxidizes according to the following equation:
4AI + 302 --> 2A1203
(a) Powdered Al (0.048 mol) is placed into a container containing 0.030 mol O2. What is limiting reactant?
(b)How many moles of the excess reactant remain?

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
