Answer : The chain of many building blocks can be called as polymers in general.
Explanation : Polymers are large units of molecules in structure which are combined by the smaller repeating units called as monomers. Every macromolecule can be defined differently, like proteins are polymers made up of amino acids. Cellulose is a polymer made up of glucose monomers. The building blocks of nucleic acids are called as nucleotides.
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
What the definition of each period and group and element and every valence electron
Answer:
Condensation is when heat turns to water vapour
Melting is when solid turns to liquid
Freezing is when liquid turns to solid
Sublimation is when solid turns to gas without passing through the liquid state
