Question: I have a new situation: Two sisters Mary and Beth were into sciences. Beth studied physics, while Mary studied chemistry and especially alkanes. They were very devoted to studying.  But I can use this background: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in – ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane with two carbon atoms. The chemical formulas and properties of methane, ethane, and other small alkanes are listed in the Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally boil and melt at higher temperatures.  What is an answer for this question: Which sister studied more about the melting points of alkanes?
Answer: Mary

Question: I have a new situation: There are two elements, Zaxon and Barton. Zaxon is an element that is further left on the period, and Barton is on the right of the period.  But I can use this background: However, when going across a period from left to right, the atomic radius actually tends to decrease. Why is this so? Each successive electron is going into the same principal energy level as the previous one, so the total amount of occupied space does not really go up significantly. Additionally, because protons are also added to the nucleus as you go across the row, the pull of the positively charged nucleus on the negatively charged electrons increases. This tighter pull leads to a slight decrease in atomic radius. As a result, the atomic radii of the elements exhibit a periodic trend, gradually tends to downward, but with a sharp spike up whenever electrons are added to a new principal energy level ( Figure below ).  What is an answer for this question: Which element has a tighter pull between the nucleus and the electron?
Answer: Barton

Question: I have a new situation: Tammy and Moe were two school mates. Moe learned about mammalian reproduction in school. Tammy learned about fish reproduction.  But I can use this background: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization.  What is an answer for this question: Which student didn't learn about fish eggs being fertilized inside of the female body?
Answer:
Moe
