Should we focus on the new material or the old material more? Which one will be more heavily concentrated on the exam?

Melissa_Aguirre1J

Up until what day will the final cover?

Melissa_Aguirre1J

What is an amphoteric compound?

Melissa_Aguirre1J

What is the difference between an ionic equation and a net ionic equation?

Melissa_Aguirre1J

Why wouldn't one pi bond be considered a double bond?

Melissa_Aguirre1J

What is the relationship between VSEPR and polarity?

Melissa_Aguirre1J

Why can't there be two sigma bonds and a pi bond in a triple bond?

Melissa_Aguirre1J

How does the addition of lone pairs affect the bond angle? I know that lone pairs are not included in the VSEPR model, but would the lone pairs affect the VESPR model in any way?

How do you determine what atom has higher polarizing power? Do we need to know that?

Melissa_Aguirre1J

How do you measure dissociation energy? Do we need to know that?

Melissa_Aguirre1J

How can you tell if something is polarizable?

Melissa_Aguirre1J

So an ionic bond is an equal sharing of electrons that do not have a charge and covalent bonds have partial charges?

Melissa_Aguirre1J

Another example would be CH3CH2OH

Melissa_Aguirre1J

An example of this would be H2C(NH2)COOH

Melissa_Aguirre1J

I know that the element with the lowest ionization energy goes in the middle, but, when you have a lot of elements, how do you determine which ones go on the side of it and on top of it?

Melissa_Aguirre1J

I know that the element with the lowest ionization energy goes in the middle of the Lewis structure. Would that element also have the highest electronegativity, or would it be the lowest? What is their relationship?

Melissa_Aguirre1J

What is the relationship between atomic radius, ionic radius, ionization energy, and electron affinity? Are atomic and ionic radius related and going in the same direction and ionization energy and electron affinity related and going in the same direction?

Melissa_Aguirre1J

Are atomic radius and ionic radius the same thing? If not, why not? Is so, why?

Melissa_Aguirre1J

How is electromagnetic radiation related to energy of the photon? Are they the same thing?

Melissa_Aguirre1J

What is the difference between the equations v=R((1/(n1^2))-(1/(n2^2))) and -hR/n^2? What are the similarities? What is their overall relationship?

M.9 Copper(II) nitrate reacts with sodium hydroxide to produce a precipitate of light blue copper(II) hydroxide. (a) Write the net ionic equation for the reaction. (b) Calculate the maximum mass of copper(II) hydroxide that can be formed when 2.00 g of sodium hydroxide is added to 80.0 mL of 0.500 m...

1.34 The work function for chromium metal is 4.37 eV. What wavelength of radiation must be used to eject electrons with a velocity of 1.5 103 kms1?

Melissa_Aguirre1J

1.69 In a recent suspense fi lm, two secret agents must penetrate a criminal’s stronghold monitored by a lithium photomultiplier cell that is continually bathed in light from a laser. If the beam of light is broken, an alarm sounds. The agents want to use a handheld laser to illuminate the cell whil...

G5.A student prepared a solution of sodium carbonate by adding 2.111 g of the solid to a 250.0-mL volumetric fl ask and adding water to the mark. Some of this solution was transferred to a buret. What volume of solution should the student transfer into a fl ask to obtain (a) 2.15 mmol Na; (b) 4.98 ...

Melissa_Aguirre1J

How do you calculate the longest and shortest wavelengths that are able to eject an electron?

Melissa_Aguirre1J

How do we calculate the change from ground state to excited state and excited state to ground state?

Melissa_Aguirre1J

How are we supposed to determine the ground state of an electron?

Melissa_Aguirre1J

Frequency is measured in Hertz or 1/sec (The units for Frequency is Hertz). The units for wavelength are meters.

Melissa_Aguirre1J

How is the work function related to the threshold energy?

Melissa_Aguirre1J

What would be considered the threshold energy?

Melissa_Aguirre1J

This is because they have a higher frequency.

Melissa_Aguirre1J

Covalent bonds are pairs of shared electrons between atoms. This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. Thus, in order to determine this, you would have to look at the periodic table.

Melissa_Aguirre1J

How do you find the excess amount of the reactant that is not the limiting reactant in a limiting reactant problem?

Melissa_Aguirre1J

What is the relationship between Molarity and Concentration? In a question where they ask us to find the concentration, can we use the m1v1=m2v2 formula?

Melissa_Aguirre1J

What is the difference between the amount of significant figures needed when multiplying and the amount of significant figures needed when dividing?

Melissa_Aguirre1J

The actual yield is the amount of the product that has actually been produced, which is usually less than the theoretical yield. The theoretical yield is the amount of the product that could be formed, once all of the limiting reactant has been completely consumed.

Melissa_Aguirre1J

The molar mass is the atomic mass expressed in grams.
