The hills and valleys decrease the height and speed of the ride. This means that the graph has a negative correlation.

By the way, I think you may have plotted your points incorrectly. The directions said to connect them all with a smooth line or curve.

Also, this is not high school chemistry. This is more likely to be elementary school science. Just make sure that you put your questions in the correct categories next time! :)

Determine the electron geometry, molecular geometry and polarity of tecl6.
Delvig [45]
The electron geometry of TeCl6 is octahedral, while the molecular geometry is octahedral, non polar. 
Octahedral geometry or six electron pairs is the basic geometry for a molecule containing a central atom with six pairs of electrons, such as TeCl6 or SF6. As we replace bonding pairs with non bonding pairs the molecular geometry changes to square pyramidal to square planar.

What is the molarity of a solution in which 175.8<br> grams of NaCl is dissolved in 1.5 L of water?
Sophie [7]
175.8 g NaCl to moles:
(175.8 g)/(58.44 g/mol) = 3.008 mol NaCl

Molarity = moles of solute/volume of solution in liters

(3.008 mol NaCl)/(1.5 L) = 2.0 M.

The molarity of this solution would be 2.0 M.

A solution is initially 0.10m in mg2+(aq) and 0.10m in fe2+(aq). solid naoh is slowly added. what is the concentration of fe2+ w
dexar [7]

Mg(OH)₂  ⇄ Mg²⁺   +   2 OH⁻

Ksp = [Mg²⁺] [OH⁻]²

6.0 x 10⁻¹⁰ = 0.10 x [OH⁻]²

[OH⁻] = 7.746 x 10⁻⁵ M

when Mg(OH)₂ 1st precipitates, [OH⁻] = 7.746 * 10⁻⁵ M

Fe(OH)₂   <—>   Fe²⁺   +   2OH⁻

Ksp = [Fe²⁺] [OH⁻]²

7.9 x 10⁻¹⁶ = [Fe²⁺] x (7.746 x 10⁻⁵)²

[Fe²⁺] = 1.32 x 10⁻⁷ M

Answer: 1.32 x 10⁻⁷ M
