Answer 1) The density of the cube will be 17.30 g/mL

We know the edge that is 1 inch, we have to convert it into cc which will be;


1" = 16.38 cc and cc = mL


The given mass is in oz, we need to convert this as well in g;


10 oz = 283.495 g;


We have the formula as Mass = Density / Volume


Substituting the values; Density = (283.495 / 16.38) = 17.30 g/mL



So the density will be 17.30 g/mL


Answer 2) The density of cube will be 1.738 Kg/L


The same procedure of conversion would be done here,


Mass in Kg will be 0.02834 Kg and Volume will be 0.0163 L


On solving with the equation as Mass = Density /  Volume;


Density = (0.02834 / 0.0163) = 1.738 Kg/L


Hence, the density will be 1.738 Kg/L

Draw the Lewis structure (including all lone pair electrons and any formal charges) for one of the four possible isomers of C3H9
Alexus [3.1K]

Answer and Explanation

The isomer picked is the N-Propylamine.

It has a lone pair of electron available on the electron rich Nitrogen and no formal charge.

Since it will be hard to draw the Lewis structure in this answer format, I'll attach a picture of the Lewis structure to this answer.

The lone pair of electron is shown by the two dots on the Nitrogen atom.

Which one of the following will change the value of anequilibrium constant?
IRINA_888 [86]

Answer:

d. changing temperature

Explanation:

The thermodynamic equilibrium constant K is defined as a quantity characterizing the equilibrium of a chemical reaction. For a reaction where concentrations are in equilibrium:

aA + bB ⇄ cC + dD

The equilibrium constant is:

k = \frac{[C]^c[D]^d}{[A]^a[B]^b}

Thus, the equilibrium constant will change if:

a. Varying the initial concentration of reactants . FALSE. The k constant doesn't depend of initial concentrations but concentration in equilibrium does.

b. Adding other substances that do not react with any of thespecies involved in the equilibrium . FALSE. The equilibrium constant just depends of substances that are involved in the equilibrium

c. Varying the initial concentration of products . FALSE. Again, equilibrium constant doesn't depend of initial concentrations.

d. Changing temperature . <em>TRUE. </em>As a thermodynamic constant, k depends of temperature thus:

K = e^(-dG/RT)

e. Changing the volume of the reaction vessel. FALSE. The changing in the volume of the reaction vessel will change just the initial concentrations of the reactants.

I hope it helps!
