According to the national institute of health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. a few beats of ventricular tachycardia often doesn't cause problems. however, episodes that last for more than a few seconds can be dangerous. ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation. based on the passage above, how will prolonged ventricular tachycardia affect blood pressure? 1. it will increase blood pressure because the ventricles are contracting with more force. 2. it will increase blood pressure because the ventricles are filling with more blood between beats. (wrongg! ) 3. it will decrease blood pressure because there is a longer rest period beats of the ventricles 4. it will decrease blood pressure because the ventricles are filling with less blood between beats.

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?

How do i turn 2 s into one in the products

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
