These items concern safety in the Determination of an Equilibrium Constant Experiment. (Select all that apply.) (a) Which of the following are hazardous properties of nitric acid? It's highly flammable. It's a potent carcinogen (causes cancer). It's corrosive. It's basic. It's an oxidant. It's a teratogen (causes birth defects). (b) Which of the following are hazardous properties of sodium thiocyanate? It's a teratogen (causes birth defects). It's highly flammable. It's an irritant. It's acidic. It's basic. It's a potent carcinogen (causes cancer). It's toxic. (c) If any of the solutions in this experiment are spilled on skin or clothing, what is the first thing to do? Flush the area with water. Clean up any spills on the floor or at your lab bench. Go to the TA and tell him/her about the spill. Neutralize the chemical with sodium thiosulfate solution.

Which of the following electromagnetic waves can create ions?

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely. analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
