415 ml of 0.275 M copper(II) nitrate solution is reacted to 25.8 g of sodium bicarbonate (NaHCO3) to form copper(II) carbonate, sodium nitrate, water and carbon dioxide. If reaction took place with 75% yield, how many grams of copper(II) carbonate forms?
A mixture of 50.0 g sulfur and 1.00x102 g of molecular chlorine gas reacts completely to form disulfur dichloride and sulfur dichloride. Find the mass of disulfur dichloride formed and determine the limiting and remaining reagents?
Choose your one favorite lipid, and another one favorite peptide (short chain amino acids). Connect this lipid and peptide together, then draw. When this lipid + peptide is assembled into water solution, draw what is going to happen in its structure. Describe and explain your answer.
The ∆H° for the reaction at 298 K is -36.4.
1/2H2(g) + 1/2Br2(1) —> HBr(g)
Calculate ∆U° at 298 K
Create your own fictitious 2-Carbon phospholipid (instead of the standard 3-Carbon). Draw this and compare side-side with standard 3-Carbon phospholipid. Provide example each. Explain shortly your comparison.
In the following chemical reaction, how many grams of the excess reactant are left over when 4.21E-1 moles of Al(s) react with 1.39E+0 moles of Cl(g)?
2Al(s) + 3Cl(g) → 2AlCl(s)
