H2(g) + I2(g) ↔2HI(g) + heat. If more I2 is added, in what direction will the equilibrium shift? Group of answer choices

uranmaximum [27]

Answer:

Towards the products, or to the right

Explanation:

There are no provided answer choices, but the answer should be <u>to the right.</u>

By Le Chatelier's principle, which basically can be summarized as "if you mess with chemistry, chemistry messes back", if more reactants are added, the equilibrium will shift to the right towards the products in order to make more products and counteract the increase in I₂.

Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The o

Answer:

The molar concentration would have to be 0,81 M.

Explanation:

The osmotic pressure equation is:

$\pi = M R T$

where:

$\pi$ : osmotic pressure [atm]

M: molar concentration [M]

R: gas constant 0,08205 [atm.L/mol.°K]

T: absolute temperature [°K]

To solve the problem, we just clear M from the osmotic pressure equation and then replace our data using the appropiate units. Clearing the variable M we have:

$M = \frac{\pi }{RT}$

We have to use temperature as absolute temperature (in kelvins), T=29+273=302 °K. Now we can replace our values in the equation:

$M = \frac{20,1 atm}{0,08205 \frac{atm.L}{mol.K} * 302 K }$

As we can see, all units will be simplified and we'll have the molar concentration in mol/L.

$M = 0,81 \frac{mol}{L} = 0, 81 M$

When the half-reactions Br2 +2e- ? 2Br- and Na ? Na+ +e- are combined, the balanced redox equation is _____. A. Na + Br2 +e- ? N

Hatshy [7]

<span>(A) Br2 +2e -> 2Br*-

(B) Na -> Na^+ +e) you need to balance the number of electrons, so multiply (B) x 2 (B) (2Na -> 2Na^+ +2e)

now, add them up and cancel the electrons (A+B) (2Na +Br_2 +2e ->2Br^- +2Na^+ +2e ) </span>
