(a)
Interpretation:
If the pressure of a sample of gas is held constant, its volume, V, is directly proportional to the absolute temperature of the gas, T. An equation for the proportionality between V and T, in which b is the proportionality constant is to be stated.
Concept introduction:
Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. When either of their ratio or their product yields a value, this value is called proportionality constant or coefficient of proportionality. The variable of y is related with another variable x via a proportionality constant c as
(b)
Interpretation:
For 48.0 grams of O2 gas at a pressure of 0.373 atmospheres, V is observed to be 93.4 L when T is 283 K. The value and units of the proportionality constant, b is to be calculated.
Concept introduction:
Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. When either of their ratio or their product yields a value, this value is called proportionality constant or coefficient of proportionality. The variable of y is related with another variable x via a proportionality constant c as y = cx. In other words, the value of proportionality constant c is given by y/x.
(c)
Interpretation:
The volume will this gas sample occupy at a temperature of 375 K is to be stated.
Concept introduction:
Generally, proportionality is stated as two varying quantities having multiplicative connection with proportionality constant. The variable of y is related with another variable x via a proportionality constant c as y = cx. In other words, the value of proportionality constant c is given by y/x.

- personality of each of them in terms of nucleophile vs. electrophile (some can be considered acids/bases but we are not looking at that here). Note you may have to use your growing intuition to figure out the personality of one of the molecules below but I believe in you! Rationalize it out based on what we have called strong versus weak electrophiles in past mechanisms. Consider using the memes below to help guide your understanding!

- The fire releases 2.80 x 107 Joules of heat energy for each liter of oil burned. The water starts out at 24.5 °C, raising the water's temperature up to 100 °C, and then raises the temperature of the resulting steam up to 325 °C. How many liters of water will be needed to absorb the heat from the fire in this way, for each 1.0 liter of crude oil burned? 4186 J/(kg°C) = heat of water 2020 J/(kg°C) = heat of steam 2,256,000 (i.e. 2.256 x 106) J/kg = latent heat of vaporization for water (at the boiling point of 100 °C).arrow_forward6 Which of the following are likely to be significant resonance structures of a resonance hybrid?
