How would a sandblasted rock differ from a rock that hasn't been sandblasted?

1 answer:

3 0

A non-sandblasted rock could be rough or smooth depending on how it was formed.

A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.

In which of the following are the pH values arranged from the most basic to the most acidic?

MAVERICK [17]

Answer:

The correct answer is : 14, 10, 7, 4, 3, 1

Explanation:

The pH of the solution is a negative logarithm of the hydronium ion's concentrations present in a aqueous solution.The pH scale ranges from 0 to 14.

Mathematically written as:

$pH=-\log[H_3O^+]$

Higher the value of pH more alkaline will be the solution.
Lower the value of pH more acidic will be the solution.
The solution with pH value 7 is termed as neutral solution.

So, from the given options of pH arranged from most basic to most acidic will be the decreasing order from 14 to 1 :

14, 10, 7, 4, 3, 1

Write an equation that shows the reaction between acetic acid and triethylamine (CH3CH2)3N. Draw all non-bonding lone electron p

Anni [7]

Answer:

-) Acid-base reaction

-) Carboxylic acid, alcohol, alkene and ketone

Explanation:

For the reaction between acetic acid and triethylamine, we will have an acid-base reaction. Therefore a salt would be produced in this case an "ammonium quaternary salt". Also, we have to remember that on this reaction the acid is the acetic acid and the base is the triethylamine. See figure 1

For the second question, we have to check the structure of Prostaglandin E1 in which we have the functional groups:

1) Carboxylic acid

2) Alcohol

3) Alkene

4) Ketone

See figure 2.

I hope it helps!
