Consider the reaction: 2 Al + 3Br2 → 2 AlBr3 Suppose a reaction vessel initially contains 5.0 mole Al and 6.0 mole Br2. What is in the reaction vessel once the reaction has occurred to the fullest extent possible? chapter 9

4 moles of and 1 mole of will be present in the reaction vessel

Explanation:

The reaction given in the question is

⇒

According to the stoichiometric coefficients of the reaction, 2 moles of requires 3 moles of so in this reaction, is a limiting reagent. So we will consider that is in excess.

Now,

Since 3 moles of requires 2 moles of

So, for 6 moles of the moles of required = = 4 moles.

Moles of remaining after the completion of reaction = 5 - 4 = 1 mole.

Again,

Since 3 moles of produces 2 moles of

So, moles of produced by 6 moles of = = 4 moles.

Therefore, after the completion of reaction, 4 moles of and 1 mole of will be present in the reaction vessel.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
