What quantity in moles of HCl are there in 35.0 mL of 0.350 M HCl?
marta [7]

Answer:

0.0123 moles

Explanation:

Concentration = Moles / Volume of solution

or you can rearrange the formula to get

Moles = concentration (moles/liter)  x  volume of solution (liter)

First convert your volume to L instead of mL.  35mL = 0.035L

moles  =  0.350 moles/liter   x    0.035 liter  (liters cancel out)

moles = 0.0123

Sulfur dioxide gas reacts with oxygen gas for form sulfur trioxide gas. the equilibrium constant for the reaction at 6000c is 4.
Art [367]
When the balanced equation for this reaction is:

            2SO3 → 2SO2 + O2 so, by using ICE table:

initial    0.391              0          0.125m

change  -X               +2X           +X

Equ     (0.391-X)         2X           0.125+X

when Keq = concentration of products / concentration of reactants

so, by substitution

    4.34  = [2X]^2 * [0.125+X] / [0.391-X]^2  by solving for X

∴ X = 0.357 m 

∴ the concentration of SO2 = 2x = 2 * 0.357 

                                               = 0.714 m

A given substance is a white solid at 250C. It melts at 1500C without decomposing, and the melt does not conduct an electric cur
joja [24]

Answer:

The substance can be best classified as a molecular substance

Explanation:

The given information are;

The physical state of the substance at 25°C = Solid state

The physical state of the substance at 150°C = Molten

Molecular substances are those with bonds formed by electron sharing among the constituent atoms and they contain a few number of atoms per molecule. Molecular compounds with molecular weight less than 100, usually exist as liquids or gases at room temperature, while those with molecular weights over 100 can be found in a solid state at room temperature.

Generally, molecular compounds are usually volatile and have a melting point less than 300°C

Therefore, the substance can be best classified as a molecular substance.
