4 moles of NaOH is present in the given 160 grams of NaOH.
<h3>How we calculate moles?</h3>
Moles of any substance will be calculated as:
n = W/M, where
W = given mass of NaOH = 160 grams (given)
M = molar mass of NaOH = 40 g/mole
Moles of NaOH is calculated as:
n = 160g / 40g/mol = 4 moles
Hence, moles of sodium hydroxide (NaOH) is 4 moles.

Answer:
B. The reactants form additional unexpected products.
Explanation:
Answer:
B) conducts electricity
Explanation:
Metals are conductors, literally meaning they conduct electricity.
One metal is liquid at room temp (there might be one more but I only know of mercury).
The reactivity depends on the placement in the periodic table.
If it conducts electricity, it can't be an insulator.
Reactivity of metals depends on the tendency to lose electrons. ... As we move down the group, the tendency to gain electrons decreases because as the atomic size increases, the effective nuclear charge decreases.
