Ans: 0.38 moles of I2 are produced.

<u>Given:</u>

Volume of I2, V = 8.5 L

At STP condition:

Temperature, T = 273 K

Pressure, P = 1 atm

<u>To determine:</u>

moles of I2 produced

<u>Explanation:</u>

Based on the ideal gas law:

PV = nRT

n = # moles of gas

R = gas constant = 0.0821 L.atm/mol-K

n = PV/RT

  = 1 atm*8.5 L/0.0821 L.atm/mol-K*273 K = 0.379 moles

Answer: 0.3794 moles of Iodine gas are produced.

Explanation:

2KI(aq)+Cl_2(&#10;g)\rightarrow 2KCl(aq)+I_2

Volume of iodine gas produced at STP =8.5 L

At STP, the 1 mol of gas occupies volume = 22.4 L

So, 8.5 L of volume will be occupied by:\frac{1}{22.4 L}\times 8.5=0.3794 moles

0.3794 moles of Iodine gas are produced.

Why can't helium bond with hydrogen?
Iteru [2.4K]
Hydrogen and Helium cannot bond together. Put aside the inertness of helium (or all noble gases), bond formation is only favored when the final state of the two elements is more stable than their initial state. ... Helium compounds has some predictions though none of them contain only those two elements.

AleksAgata [21]
Hrxn = Q reaction / mol of reaction
mol of reaction = M * V = 10 * 1 = 10 mmol = 0.01 mol
Q water = m * C * (Tf - Ti)
             = (10 + 10) (4.184) (26-20) = 502.08 J
Q reaction = - Q water = -502.08 J
Hrxn = -502.08 / (0.01) = - 50208 J = - 50.21 kJ/mol
