Answer: Option 1, 4 and 5 describe acids accurately.
Explanation:
Option 1: Acids have a sour taste because of the concentration of 
ion.
Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as 
is a strong acid which can burn skin as well as fabric.
Option 3: Acids need electrons to release ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.
Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce ions.
Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
B: Liquid take the shape of their container.
Answer:
2.675 moles of Chlorine gas are required
Explanation:
Chlorine gas, Cl2, reacts with NaBr to produce NaCl and Br2 as follows:
Cl2 + 2NaBr → 2NaCl + Br2
<em>Where 1 mole of chlorine gas produce 2 moles of NaCl</em>
<em />
Thus, to produce 5.35 moles of NaCl are required:
5.35mol NaCl * (1mol Cl2 / 2mol NaCl) =
<h3>2.675 moles of Chlorine gas are required</h3>
