It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression…

The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 8.0 g • She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 48.930 g. • She added water to the graduated cylinder and dissolved the potassium…

A direct enzyme-linked immunosorbent assay (ELISA) test on a patient's sample is shown below. Development of a strong (dark) color reaction would indicate: 1 Antibody is adsorbed to well. 2 Patient sample is added; complementary antigen binds to antibody. 3 Enzyme-linked antibody specific 4 Enzyme's substrate () is added, for test antigen is added and binds and reaction produces a product that causes a visible color change (O). to antigen, forming sandwich. A low concentration of a specific antigen in the patient's sample O A high concentration of a specific enzyme in the patient's sample The patient's antibody is specific for the enzyme's substrate O A high concentration of a specific antigen in the patient's sample A high concentration of a specific antibody (against the test antigen) in the patient's sample

When the paramagnetic species are very close together, or are separated by a species that can transmit magnetic interactions, this will give rise to а. magnetically dilute species. b. ferromagnetism or antiferromagnetism. С. only antiferromagnetism. d. only ferromagnetism

Given the Ksp for Ag2CrO4 is equal to 1.20 x 10-12, calculate the percent error in your experimentally determined value for average Ksp (this will be an extremely large percentage – think about why).
