You forgot one...and that happens to be the answer---> Accuracy
Answer:
1) The concentration of HCl = 0.1 M.
2) The table that can be used to organize the information correctly is C.
Explanation:
<u><em>1) The concentration of HCl:</em></u>
- We know that the no. of millimoles of the acid is equal to the no. of millimoles of the base at the neutralization point.
which means that: <em>(MV)HCl = (MV)NaOH,</em>
M of HCl = ??? M, V of HCl = 25.0 mL.
M of NaOH = 0.2 M, V of NaOH = 12.5 mL.
∴ M of HCl = (MV)NaOH/V of HCl = (0.2 M)(12.5 mL)/(25.0 mL) = 0.1 M.
<em>2) The table that can be used to organize the information correctly is C</em>
<em></em>
<em>Table A and B are the same and reported volume of HCl and NaOH is wrong.</em>
<em>Table C is right, contain the correct volumes and concentration of NaOH and missed the concentration of HCl which is 0.1 M.</em>
<em>Table D reported the volume and the concentration of HCl wrongly and also the concentration of NaOH. The data reported of HCl and NaOH is reversed.</em>
Answer:
true
Explanation: becuase if you add the same liquid to a small container and then add it to a big container its going to have the same liquid amount it started with
Answer:
These particles are all called atoms.
Explanation:
Atoms are referred to as the building blocks of all matter. This is because atoms are the smallest pieces that all matter can be broken down into, whether the matter is in a solid, liquid or gaseous state. Atoms combine to form bigger particles called molecules. These molecules are what forms the objects in our surrounding environment. Atoms are comprised of three particles: electrons which have a negative charge, protons which have a positive charge and neutrons which have no charge.
