Answer:
-0.044 V
Explanation:
The overall electrode potential is usually estimated by subtracting the potential of the reference electrode from the potential of the system in question. In the given problem, the standard electrode potential of silver-silver chloride with respect to the standard hydrogen electrode is +0.197 V. In addition, the potential of the calomel reference electrode with respect to the standard hydrogen electrode is +0.241 V. Using the data above, the potential of with respect to silver-silver chloride is equivalent to 0.197-0.241 = -0.044 V.
Answer: C = 0.014M
Explanation:
From n= m/M= CV
m =43.5 M= 148, V=850ml
43.5/148= C× 0.85
C= 0.35M
Applying dilution formula
C1V1=C2V2
C1= 0.35, V1= 25ml, C2=?, V2= 600ml
0.35× 25 = C2× 600
C2= 0.014M
Answer:
1.51834×10^22
Explanation:
Number of atom=Mass/Molar Mass × avogadros constant
2.3g/91.224g/mol × 6.203×10^23
Answer:
4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.
Explanation:
By ideal gas equation:
Number of moles (n)
can be written as: 
where, m = given mass
M = molar mass
where,
which is known as density of the gas
The relation becomes:
.....(1)
We are given:
M = molar mass of chloroform= 119.5 g/mol
R = Gas constant = 
T = temperature of the gas = 
P = pressure of the gas = 1.00 atm
Putting values in equation 1, we get:
4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.
The moon is what makes currents so if there was no moon there would be no current in our oceans. The way it makes currents is from the gravitational pull.
