Answer:
If you are given a chemical equation and specific amounts for each reactant in grams, you have to follow these steps, in order, to determine how much product can possilby be made:
1. Convert each reactant into moles of the product.
2. Determine which reactant is the limiting reactant.
3. Convert the moles of product, from the limiting reactant, to grams.
Explanation:
It is true that the major ways people are exposed to toxins are by ingesting them, inhaling them, injecting them, or absorbing them through the skin.
<u>Explanation:</u>
Toxins can enter in four various ways into our body often referred as "route of exposure". It is one among many factors affecting toxicity.
Inhalation: When the toxin is a gas, it is usually absorbed into the body by inhalation. Inhalation of toxins may cause respiratory and lung damage. Eg: cigarette smoke
Absorption: If a toxin enters the human eye or skin, it can be absorbed into the bloodstream. This is called absorption. The skin can prevent some toxins from entering the body. For example: work stations (gas stations) where people work with toxins
Ingestion means that the person has ingested the toxin. Some chemicals cannot get into blood from digestive tract. For example: drinking contaminated water.
The injected toxin enters the body when the person carrying the toxin breaks the skin. Injections can end in veins, muscles or just under the skin. Eg: Botulinum (used to get rid of wrinkles)
In bio-chemistry, poison, a natural or synthetic substance that damages living tissue and has a harmful or lethal effect on the body, regardless of whether it is absorbed, inhaled or injected through the skin.
Let P be the product solution, A be the 30% alcohol solution and W be the distilled water.
If we multiply the percentage of alcohol to the volume of the stream, we can obtain the amount of alcohol. Alcohol in the product is the sum of the alcohol in the solution and water.
Vp x 0.25 = 50 x 0.3 + Vw x 0
Vp = 60 gallons of product solution
Volume of product = volume of alcohol sol + vol of water
60 = 50 + Vw
Vw = 10 gallons
10 gallons of water must be added.
