A5.5 g sample of a substance contains only carbon and oxygen. carbon makes up 35% of the mass of the substance. the rest is made of oxygen. you are asked to determine the mass of oxygen in the sample. which of the following expressions demonstrates a mathematical procedure to solve this problem using the proper order of operations? 1) ((100 - 35)/100) times 5.5 grams = 2)100 - 35/100 times 5.5 grams = 3) 100 - (35/100) times 5.5 grams = *recall that to calculate a percent of an amount in grams means you have to convert the percent to a number and multiply by the amount in grams. for example, 50% means 50 out of 100, or 50 hundredths. so 50% of 10 grams is 0.50 times 10 grams. you need to take 0.50 and multiply it by 10 grams to determine 50% of 10 grams is 5.0. (50% and 10 grams are examples and not numbers for this problem.)

Description: biological systems 5 differ from chemical systems when it comes to equilibrium. in a chemical system once equilibrium is met, no other reactions occur. in a biological system, a dynamic equilibrium is used when a substrate is turned into a product, another reaction creates the same substrate thus keeping the concentrations stagnant. this allows for cells to continually make new compounds without messing the delta g for the systems instructions: write a response to the following prompt and then respond to your peers. your individual response is due thursday at midnight (cst) your response to your peers is due saturday at midnight (cst) prompt: propose what would happen if a living cell all the sudden reached chemical equilibrium. also discuss the effects of build up of a particular substrate on a biological system. how would this affect overall delta g's?
