Calculate the amount of heat required to completely sublime 99.0 g of solid dry ice CO2 at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 KJ/Mol
Did you notice a difference in the protists when the slowing agent was used? Which members were you able to see more clearly? Were there species that were still moving too fast to see clearly? Could you identify any species specifically? Do any of them look similar to specimens you observed in the first lab?
Phenylketonuria (PKU) is caused by homozygosity for a recessive allele and can cause a severe form of mental retardation if not detected early. The prevalence of PKU (genotype aa) is 1 per 15,000 newborns in the United States according to the National Institutes of Health (2001). Given the above data, what is the expected allele frequency […]
This raises a challenging question: In the biologically realistic setting of an intact plant infested with living microorganisms, how much MAMP needs to be present, and in what plant tissues, for defenses to be triggered?
Assume that 21-day litter weight for pigs averages 98 lbs for Breed A and 106 lbs for Breed B. Litters of crossbred pigs from these two pure breeds average 113 lbs at 21 days. What is the % hybrid vigor for 21-day litter weight for these crossbred pigs
We need 1.00L of a formic acid/formate (Ka= 1.80×10-4) buffer with a starting pH of 3.500. It must be able to resist the addition of 20.00mL of 0.250M NaOH while remaining below pH 4.150. How many mL of 0.500M stock acid and 0.250M NaOH base solution must be used in preparation of this buffer?
What observation supports the assumption that all the iodine reacted with the zinc?
Consider the flask apparatus below, which contains 2.00 L of H2 at a pressure of 349 torr and 1.00 L of N2 at an unknown pressure. If the total pressure in the flasks is 317 torr after the stopcock is opened, determine the initial pressure of N2 in the 1.00 L flask.
