Helppppp….. is this right?

A dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.

A chemical reaction is the process by which substances called reactants are transformed to another substance known as products through the breaking up or building up of bonds between the reactants.

There are different types of chemicals reaction which includes condensation reaction.

Condensation reaction involves the combination of two smaller molecules known as monomers to for one larger molecule known as polymer with the loss of water molecule.

Condensation reaction is specifically called dehydration reaction due to the loss of water molecule that is involved.

Therefore, a dehydration reaction (or condensation reaction) is the process in which water molecules are produced as a polymer is formed from monomers.

Answer:

what is the story about actually.i think it's from ur lesson

Explanation:

certain breads mold easily...(fact)..

especially white bread., when exposed to any moisture, from refrigeration, or freezing..

when taken out of (cold environment), humidity in air causes molding because you take it from cold to/warm environment.

check expiration dates, keep refrigerated, and inspect 4 molding. Companies like WMART, buy in bulk, when on shelf, defrosts,, then has molding within expiration dates..

Many of the great scientists were religious. But the answer is not D.

A scientist may have strong opinions. That was certainly true of Newton. Most of the time he was right. Still the answer is not C. Science requires an open mind.

The answer is between A and B. Many discoveries were made looking at the natural world. That may provide the inspiration. But I don't think it is the answer. I'm going to say A

Answer:

electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

There are various type of chemical reactions in chemistry like combination reaction , displacement reaction. One of these is the decomposition reaction. The correct option is option D.

Decomposition reaction is the one in which molecules breaks down in its constituent in presence of energy. Energy can be in any form, it can be light energy , heat energy.

Decomposition of water is done by providing electricity and the reaction is called electrolysis. Lysis means to break. To give decomposition reaction molecule must have more than one element.

The fourth reaction describe a decomposition reaction (NaNO3 decomposed to become NaNO2 and O2). First and third reaction are considered combustion reaction (reacting with oxygen). Second reaction is acid-base reaction.

Therefore, the correct option is option D.
