The concentration of the acid decreases
Compounds. They both have more than one element in them
Answer : The correct match is:
1 positive charge = 1 negative charge
2 positive charges = 2 negative charges
3 positive charges = 3 negative charges
Explanation :
As we now that there are three subatomic particles which are protons, electrons and neutrons.
The protons and neutrons are located inside the nucleus and electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and neutrons are neutral.
As we know that all the things are made up of charges and opposite charges attract to each other.
In a neutral atom, the positive charges and negative charges are balanced in an object. That means, in neutral atom the number of positive charges are equal to the negative charges.
So we can say that:
1 positive charge = 1 negative charge
2 positive charges = 2 negative charges
3 positive charges = 3 negative charges
Nylon 6,6 is a common example of a polyamide.
<em>Polyamides</em> are polymers that contain <em>repeating amide (-CO-NH-) linkages</em>.
The structure of Nylon 6,6 is
[-NH-(CH_2)_6-<u>NH-CO</u>-(CH_2)_4-CO-]_<em>n</em>
where <em>n</em> is a large number.
The numbers in the name showow that there are six carbon atoms on either side of an amide linkage.
All of this involdes cell of different types
