<u>Answer:</u> The concentration of weak acid is
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of weak acid is
Answer:
A
Explanation:
Because it is the greatest
Answer:
1.14 mols
Explanation:
n(mols) = mass/molecular mass
26.3/ 23 = 1.14
Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
