Design a project that will show information about photosynthesis
and cellular respiration and the connections between the two. Terms
to Include in the Project: (these terms must be in the
project)
Carbon Dioxide (CO2), Oxygen (O2), Glucose (C6H12O6),
Sun/Sunlight/Light, Water (H20), ATP, chloroplast,
mitochondria
Concepts to Include: Function of both processes, location of both
process, reactants of both, products of both, how the two processes
are related in terms of the light dependent, light independent,
glycolysis, citric acid cycle, electron transport chain, what is
ATP and how does it do its job.

Potassium cyanide (KCN) reacts with acids to form a deadly poisonous gas, hydrogen cyanide (HCN). The reaction is represented by the equation:
KCN(aq) + HCl(aq) è KCl(aq) + HCN(g)
If a sample of 0.150 g of KCN is treated with an excess of HCL, calculate the amount of HCN produced, in grams.

1. Why is it important to know the difference between acids and bases, in terms of safety?
2. Ionic bonds, covalent bonds and hydrogen bonds all help to hold chemical entities together. Distinguish between these types of bonding and explain which type of bonding is responsible for matching the base pairs in DNA.

One method for preparing alcohols involves hydration of alkenes with aqueous acids (such as sulfuric acid and water). In light of this fact, it seems surprising that the phosphoric acid promotes the elimination of cyclohexanol to give cyclohexene plus water at high temperatures, the very components required to make cyclohexanol. Why was your experiment successful?

Selenocysteine has pKa values for the a-amino, a-carboxyl, and sidechain groups of 10.0, 1.90, and 5.4, respectively. the sidechain looks just like cysteine, but has a selenium in place of the sulfur. In terms of protonation and charge, selenium behaves like oxygen or sulfur. Answer the following.
1) what is the overall charge of selenocysteine at pH 6.2?
