Consider the reaction . At equilibrium, a 10 L vessel contains 1.5 moles of HI, 0.1 moles of I2 and 0.3 moles of H2. Which direc

tion will the reaction proceed if 2 moles of HI, and 0.5 moles of both I2 and H2 are mixed in a separate 10 L vessel

The reaction will proceed in the forward direction if 2 moles of HI and 0.5 moles of both I_2  and H_2  are mixed in a separate 10 L vessel.

<h3>What is equilibrium?</h3>

In chemistry, equilibrium is the condition existing when a chemical reaction and its reverse reaction occur at equal rates.

If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.

In the first case K < Q, but in the second case K > Q, so the reaction will proceed forward in the forward direction.

Calculate the number of moles of solute present in 55.0 mg of an aqueous solution that is 1.45 m NaCl. Assume that for dilute aq
Aloiza [94]

Answer:

0.00007975 mole

Explanation:

Number of moles can be calculated as; mass of solute/volume of solvent or concentration of solution x volume of that solution.

In this case:

Concentration of solution = 1.45 M

Mass of solvent (water in this case) = 55.0 mg

55.0 mg of water is equivalent to 0.55 ml of water.

Therefore, volume of solution = 0.055 ml

Hence, number of moles of solute = molarity x volume

                                                           1.45 x 0.000055 = 0.00007975 mole

How many neutrons are in a nucleus of uranium-238?
LenaWriter [7]

Answer:

146

Explanation:

The mass of uranium- 238  is  238  mass units. The total mass of an element is the sum of its protons and neutrons.  There are  92  protons in this isotope, and its mass is  238 , so that means that there are,  238 − 92 = 146  neutrons. Thus, as weird as it may seem, the answer must be D.
