chrischona2015.org=4The molecule is CF4 is the only non polar molecule from the options above. To find if a molecule is polar or non polar, you"d have to draw them (or at least visualize the shape in your head).1. HCl is linear (with a positive and a negative side, therefore polar)2. NH3 is trigonal pyramidal (polar)3.H2O is bent/angular (polar) 4.CF4 is square planar (non polar)

A nonpolar covalent bond is when electrons are shared equally between atoms. Final chrischona2015.org: CF4 is a non polar molecule 


4. Why is it important to not rely solely on visual inspection of a fiber to determine its identity?

chrischona2015.org:

Sometimes, it requires years of experience in handling fibers and fabrics to be able to expertly identify the fiber being inspected.

Explanation:



Carbon tetrachloride can be produced by the following reaction: Suppose 1.20 mol of and 3.60 mol of were placed in a 1.00-L flas

The given question is incomplete. The complete question is :

Carbon tetrachloride can be produced by the following reaction:

*

Suppose 1.20 mol

*
of and 3.60 mol of
*
were placed in a 1.00-L flask at an unknown temperature. After equilibrium has been achieved, the mixture contains 0.72 mol of
*
. Calculate equilibrium constant at the unknown temperature.

chrischona2015.org: The equilibrium constant at unknown temperature is 0.36

Explanation:

Moles of

*
= 1.20 mole

Moles of

*
= 3.60 mole

Volume of solution = 1.00 L

Initial concentration of

*
=
*

Initial concentration of

*
=
*

The given balanced equilibrium reaction is,

*

Initial conc. 1.20 M 3.60 M 0 0

At eqm. conc. (1.20-x) M (3.60-3x) M (x) M (x) M

The expression for equilibrium constant for this reaction will be,

*
\times }{^3}" alt="K_c=\frac{\times }{^3}" align="absmiddle" class="latex-formula">

Now put all the given values in this expression, we get :

*

Given :Equilibrium concentration of

*
, x =
*

*

*

Thus equilibrium constant at unknown temperature is 0.36
