Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.
Hope this helps.
Answer is A) reactants
They originally enter the chemical reaction and are changed by it, the products are a result of this procedure.
Overall, an atom is neutral charged. The Bohr model was for years accepted as the final authority because it agrees so well with experiment and observation. In this model an atom consists of a nucleus containing protons and neutrons. The neutrons are zero charge so we can forget them in looking for charges. For each proton (1 positive charge) there is always 1 electron (1 negative charge) in orbit around the nucleus. thus an atom has a equal number of electrons and protons and their net charge is zero.
We can do things to temporarily up set this natural balance (we call this electricity) but the atoms will eventually return to their naturally balanced state
Answer:
0.082 M
Explanation:
First we calculate the moles of KOH added, by multiplying its volume and concentration:
- 0.22 M * 16 mL = 3.52 mmol KOH
Given that <em>one mole of acid reacts with one mole of base</em>, in the lactic acid sample there were 3.52 acid moles as well.
Finally we divide the acid moles by the volume, to calculate the concentration:
- 3.52 acid moles / 43 mL = 0.082 M
A substance that is present at the end of a chemical reaction or which we get after the chemical reaction that's called Product.
