Corrosion. Metals tend to form oxide and over time, they rust. ( 2 FeO(OH) ⇌ Fe2O3 + H2O). <span>Gold and platinum on the other hand are noble metals and remain stable in their pure form. Thus, no electron loss and no oxidation.</span>

How many milliliters of a 0.215 molar solution are required to contain 0.0867 mol of NaBr

JulsSmile [24]

Answer: 403ml

Explanation:

$M=\frac{mol}{L}$

Solve for L;

$L=\frac{mol}{M}\\L=\frac{0.0867mol}{0.215M}\\ L=0.403L$

Convert to mililiters

$0.403L(\frac{1000ml}{1L})=403ml$
