How did the surface area of the metal strip expose to the solution affect the
frez [133]

Answer:

See explanation below

Explanation:

In an electrochemical cell, electricity is obtained by the gradual deterioration of the anode.

Hence, surface area of the metal will affect the length of time within which the electrochemical cell works.

The greater the surface area of the metal, the longer the electrochemical cell can function and the greater the quantity of electricity produced, hence the answer above.

d1i1m1o1n [39]

Answer:17.955atm

Explanation:Pv=nrt

P= nrt/v

P= 7.25*0.08205*360/11.90

P= 214.1505/11.90

P=17.995atm

Be sure to answer all parts. For an aqueous solution of sodium chloride (NaCl), determine the molarity of 4.05 L of a solution t
SpyIntel [72]

Answer:

0.824\ \text{M}

5.62\ \text{L}

20.89\ \text{mol}

Explanation:

Molar mass of NaCl = 58.44 g/mol

Mass of NaCl = 195 g

Volume of solution = 4.05 L

Molarity of solution is

\dfrac{195}{4.05}\times \dfrac{1}{58.44}=0.824\ \text{M}

The molarity of the solution is 0.824\ \text{M}

Moles of NaCl = 4.63 mol

Volume is given by

\dfrac{4.63}{0.824}=5.62\ \text{L}

The volume of the solution that contains the required amount NaCl is 5.62\ \text{L}

Volume of solution = 25.35\ \text{L}

Moles of solution is given by

0.824\times 25.35=20.89\ \text{mol}

The number of moles of NaCl is 20.89\ \text{mol}.
