Explanation:
<em>The duration of flushing the eyes at the eyewash station in case of accidental contact with chemicals depends of the nature of the chemical.</em>
If the chemical is known to be a <u>non-irritant or mild-irritant</u> one, a <u>5-minute </u>washing time is recommended as the first aid. before seeking the help of a physician,
For <u>moderate to severe irritant</u> chemicals, an immediate <u>15-20 minutes</u> washing period is recommended before seeking further medical help.
For <u>corrosive and strong alkalis</u> chemicals, <u>30 and 60 minutes</u> washing are recommended respectively before seeking the attention of a physician.
However, if the nature of the chemical is unknown,<u> a minimum of 20-minutes washing is generally recommended</u> as first aid before seeking immediate medical help.
#1. An element or ion that has lost two electrons must have a net charge of 2+, because it has two more protons than electrons, therefore the answer is Mg2+
#2. aluminum ions have an oxidation state of 3+ and fluoride has an oxidation state of 1-, therefore I’m order for the charges to cancel you need 3 fluoride ions.
Therefore, the answer is AlF3
Answer: a rection will most likely occur if the colliding partilces have the proper orientation and energy.
The reactions occur becasue the molecules collide.
But not all the collisions result in a reaction.
The collisions have to meet some requirements.
Two of the basic requirements is that the collision has enough energy to overcome the activation energy and that the molecules collide in the riight way.
When two molecules react it is necessary that one element of one of the molecules interact when a specific element or group in the other molecule. That is the orientation must be the right one.
Collisions that to not have the proper orientation or enough energy will not cause reaction (changes in the bonds of the molecules).
Answer:
large intestine is right below the stomach and gallbladder and has the small intestine in the middle
works mainly with the digestive system
The large intestine gets rid of the undigested food that the small intestine could not absorb and reabsorbs water from the digestion
other organs include:
pancreas
small intestine
gallbladder
liver
stomach
esophagus
salivary glands
the function of the large intestine is to get rid of waste, absorb water, and absorb any nutrients which did not get absorbed in the small intestine
