Answer:
Using the sprayer on your sink if you have one
Explanation:
If a chemical gets into your eye, you will need to flush the eye thoroughly with water in order to get the chemical out of the eye before it causes any kind of damage to the eye.
This could normally be done in an eye wash station. However in the absence of an eye wash station, one could use the sprayer of the sink if he/she has one. This will deliver water to completely flush the eye at lower pressure.
Answer:
d. 10
Explanation:
The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12
Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.
The confusing thing is that + means subtract and - means add here.
Hope this helps.
