Since the water is at 100 degrees then it take 40.6 kj/mol to change 1 mole of water at 100 degrees into steam at 100 degrees
the moles of water 8.22mol
since one mole take 40.6kj/mol 8.22mol will be =
8.22mol x 40.6 kj/mol =333.732 kj

When agno3 was added to test tube d it reacted with cl to form agcl precipitate. Did this result in a shift to the right or the

AlekseyPX

Answer:

Reaction will move rightwards.

Explanation:

Hello there!

In this case, according to the proposed question, it turns out possible for us to figure out the effect of the addition of silver nitrate, by using the following representative equation for the formation of the silver chloride precipitate:

$Ag^+(aq)+Cl^-(aq)\rightleftharpoons AgCl(s)$

Now, due to the addition of silver nitrate, we will be actually adding silver ions to the solution, which means that, in terms of the Le Ch atelier's principle, the reaction will shift to the right towards the formation of more silver chloride precipitate.

Best regards!

Calculate the standard potential for a cell that employs the over-all cell reaction: 2Al(s) + 3 I2(s)→2 Al+3 + 6 I- From reducti

Valentin [98]

Answer:

Explanation:

2Al(s) + 3 I₂(s) → 2 Al⁺³ + 6 I⁻

Aluminium is oxidised and iodine is reduced .

so cell potential = Ereduction - Eoxidation

Al⁺³ + 3e = Al - 1.66 V

I₂ + 2 e = 2 I⁻ 0.54 V

= .54 - ( - 1.66 )

= 1.66 + .54

= 2.2 V
