Bull sharks have the unique ability of keeping salt in their bodies even freshwater
<u>Answer:</u> The correct answer is
<u>Explanation:</u>
We are given:
The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, silver will always undergo reduction reaction will get reduced.
Chromium will undergo oxidation reaction and will get oxidized.
The half reactions for the above cell is:
Oxidation half reaction:
Reduction half reaction: ( × 3)
Net equation:
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
Hence, the correct answer is
M=n(pie)/RT
n=osmotic pressure(1.2 atm)
M=molar of the solution
R=gas constant(0.0821)
T= temperature in kelvin 25+273
M=[1.2atm /(0.0821L atm/k mol x 298k)]=0.049mol L
M= moles of the solute/ litres of solution(250/1000)
0.049= y/0.25
moles of solute is therefore =0.01225mol
molar mass=33.29 g/0.01225mol=2.7 x10^3g/mol
Answer:
Solids.
Explanation: Most elements are solids, only 11 are gases and 2 are liquids.
