Rocks are made of many different materials. Different types of rocks are made from different sediments. Depending on the sediment that the rock is made of depends on how strong the rock will be. There are six main types of sedimentary rocks. All of the rocks are different colors depending on the sediments it consist of.
Answer:
a. Sodium cyclopentanecarboxylate
b. No reaction
Explanation:
In this case, in the cyclopentanecarboxylic acid we have a <u>carboxylic acid</u> functional group. Therefore we have an "acid". The acids by definition have the ability to produce hydronium ions (
).
With this in mind, for molecule a. we will have an <u>acid-base reaction</u>, because NaOH is a base. When we put together an acid and a base we will have as products a <u>salt and water</u>. In this case, the products are Sodium cyclopentanecarboxylate (the salt) and water.
For the second molecule, we have the hydronium ion (). This ion can not react with an acid. Because, the acid will produce the hydronium ion also, so <u>a reaction between these compounds is not possible.</u>

Answer:
A, B, and C are the correct answers.
Explanation:
The reason why solid, liquid, and gas are the most common of the elements because usually in school they teach you more about those 3 elements more than plasma ( from where I am ). Also, all of these states behave differently. Liquid is a substance that flows freely but is of constant volume, having a consistency like that of water or oil. Solid is firm and stable in shape. And gas is an air like substance. I'm not sure how to explain this more, it sounded better in my head. Hope this helped though!

Answer:
S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
Explanation:
Given data:
LD50 for S. aureus alpha toxin 0.45 \mu g/kg
ID50 for same mouse density found to be 200,000
From the data information given above Staphylococcus aureus was done on mice. The result show that LD50 is found to be 0.45\mu g/kg and ID50 found to be 200,000 on same mouse population
the result taken together mean that S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
