Ora had a chemical splash into her eyes. she immediately told her teacher and went to the eyewash station. she then proceeded to wash her eyes out until they no longer hurt, which took about ten minutes. she then returned to her station, cleaned up any chemical spills according to directions, and started her project over. which best describes her error? a-she should not have started over after the chemical spill. b-her teacher should have cleaned the chemical spill. c-she should have washed her eyes for at least fifteen minutes. d-she should have used the safety shower.

Hello!

Most teachers and sources recommend students who have been exposed to chemical to flush or wash the exposed area for about 15 to 20 minutes. In this case, Ora took 10 minutes instead of 15 to 20 minutes. So therefore, the answer is C, she should have washed her eyes for at least fifteen minutes.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
