1. Given the following reaction: HCl + Al --> AlCl3 + H2

If 15.0 g of Al are reacted with 525 ml of 2.75 M HCl, how many g of AlCl3 could be produced?

2. Given the following reaction:
LiOH + CaCO3 --> Li2CO3 + Ca(OH)2

If 250.0 mL of 0.125 M LiOH is reacted with 375.0 ml of 0.175 M CaCO3, how many g of Li2CO3 could be produced?

The ammonia molecule in the diagram has the observed bond orientation because

In this problem, you will determine the biosynthetic cost of generating the amino acid serine from glucose used as food. the biosynthetic costs of all the amino acids are given in table 5.1, and now you will get a first-hand sense of how to obtain those values. visit the website and find the metabolic pathways for serine synthesis and glycolysis. the starting molecule of the serine synthesis pathway is an intermediate in glycolysis. how many molecules of glucose must be taken up to provide the carbon skeleton used to make serine? draw the biochemical pathway starting with glucose and ending in serine, labeling the energy-requiring and energy-generating steps. how many molecules of atp are consumed and created along the way? how many reducing equivalents of nadh and nadph are consumed or created along the way? in order to answer this question completely, you may need to consider a few other pathways as well. for example, it is likely that the displayed glycolysis pathway does not actually start with glucose. to get glucose 6-phosphate from glucose requires 1 atp. one of the steps in the serine synthesis pathway is coupled to a conversion of l-glutamate to 2-ketoglutarate.
