Melting point is in relation to the lattice energy, and the higher the magnitude of the charges within the compound, the higher lattice energy and therefore melting point.

QUESTION 1/4 - Exam #2

Electronegativity is described as the tendency for an atom to attract additional electrons. Fluorine is the most electronegative element as it only needs one more electron to have a full octet, As such, the electronegativity of each element will decrease as you get farther away from Fluorine on the periodic table in all directions.

QUESTION 2/4 - Exam #2

Farmer Harold is training his new farmhand to handle the cows during morning milking. He explains that some cows pull harder than others on their feed. Which cow has the weakest pull (the least electronegativity)?

The number of hybridization orbitals correlates with the number of electron regions, with bonds and lone pairs being counted each as one electron region, for in this case, a total of five.

question 3/4 - Exam #2

If Farmer Harold has three connected stalls filled each with two cows (three singular bonds) and two separate isolated stalls with two cows each (two lone pairs), what is the stall arrangement type (assigned hybridization)?

All molecules will have london dispersion forces. but in the case of acetone, which is a polar molecule, it will have dipole-dipole interactions, but not hydrogen bonding since the hydrogens are not directly bonded with the oxygen.

question 4/4 - Exam #2

Farmer Harold decides to use acetone (C₃H₆O) as a solvent for the pesticide he will use on his crops. What intermolecular force is the dominant force for acetone?

Determine the amount of moles of Zinc are obtained, then use Stoichemetry to determine the amount of moles of nitric acid is obtained, where nitric acid can then be converted into grams. The Percent Yield is equal to the Actual Yield of Nitric Acid divided by the Theoretical Yield of Nitric Acid, then multiplied by 100.

question 1/4 - Exam #3

Farmer Harold gives his pigs 30.5 g of zinc (Zn) to react with plenty of nitric acid (HNO₃). After the reaction, the pigs produce 65.2 g of zinc nitrate (Zn(NO₃)₂). What is the percent yield of zinc nitrate?

(Click explanation above to Feed the pigs)

Zn(s) + 2HNO₃ (aq) --> Zn(NO₃)₂ (aq) + H₂ (g)

An acid-base reaction involves the transfer of a hydrogen ion (H⁺) from an acid to a base, typically forming salt or water.

question 2/4 - Exam #3

Farmer Harold is watching three different reactions happen in his barn. In one reaction, a 'pig-acid' donates a proton to a 'barn-base' that accepts it. Which of the reactions below shows this acid-base behavior?

(Click explanation above to Feed the pigs)

AgNO₃ (aq) + NaCL (aq) --> AqCl + NaNO₃

Feed

Zn (s) + Cu(NO₃)₂ (aq) --> Zn(NO₃)₂ + Cu

H₂SO₄ (aq) + Sr(OH)₂ --> 2H₂O + SrSO₄

Make sure that the reactants and products are equal to each other in the amount of elements that are on each side of the equation. This ensures that the equation is following the law of consevartion of mass.

QUESTION 3/4

QUESTION 3/4 - Exam #3

Farmer Harold is mixing copper (Cu) with nitric acid (HNO₃) in the pig barn. He's trying to balance the reaction but needs help figuring out how many nitrogen dioxide (NO₂) 'pig tails' are released (what is the number infront of NO₂)?

(Click explanation above to Feed the pigs)

_Cu + _HNO₃ --> _Cu(NO₃)₂ + _NO₂ + _H₂O

A Strong Base is a compound that completely dissociates in water, producing a high concentration of hydroxide ions (OH⁻)

question 4/4 - Exam #3

Farmer Harold is sorting chemicals in his pig barn. One of them is a strong base -- strong enough to clean the pig pens in one swipe. Which of the following is the strong base?

Depending on which variables are held constant in the ideal gas law equation, the resulting variables are only inverse when volume vs. pressure is changed, but the rest display direct relationships.

question 1/4 - Exam #4

Farmer Harold is getting ready for sheep-shearing day and is checking the air systems that power his shears. As he adjusts different settings, he notices that some pairs of variables change in opposite ways—when one goes up, the other goes down. Which of the following demonstrates an inverse relationship in Farmer Harold’s shearing shed?

Volume vs. Pressure

effusion occurs when gas molecules escape without collision through a small hole into a vacuum, as the picture depicts. It is not an example of diffusion as the molecules are not moving from an area of low concentration to an area of high concentration.

question 2/4 - Exam #4

All the sheep have to go single file through a small opening in the gate to get sheared. What is this situation and the corresponding picture an example of?

(Click explanation above to sheer the sheep)

Diffusion

Shearing

Confusion

Effusion

Convert both elements and their respective masses into moles using molar mass, then use the number of moles of phopshorus and divide by the total number of moles combined between the two comonents of the mixture

question 3/4 - Exam #4

Farmer Harold is preparing special shearing-shed lanterns that burn a mixture of two gases: P₄ gas from mineral blocks and N₂ gas from the air tanks. For today’s long shearing session, he fills a lantern with 182.9 g of P₄ and 26.3 g of N₂. What is the mole fraction of phosphorus (P₄) in Farmer Harold’s gas mixture?

Deviations from the ideal gas law and therefore ideal behavior at STP include that of intermolecular forces and molecular size. As H₂ is a small, nonpolar molecule, with weak dispersion forces, it deviates the least from ideal compared to the other molecules.

question 4/4 - Exam #4

Farmer Harold is setting up his sheep-shearing shed for the season. To power the air clippers, he uses different gas tanks, each filled with a different type of gas. Some gases behave very predictably under normal shed conditions (like STP), while others don’t behave quite as ideally. Which of the following gases would give Farmer Harold the most ideal behavior during shearing at STP?

(Click explanation above to sheer the sheep)
