Answer: covalent bond
Explanation: Yeah that's the answer
C. Gravity acting on the edges of plates and convection in the mantle. So you were correct!
Answer:
Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)
Explanation:
In writing the cell notation for an electrochemical cell, the anode is written on the left hand side while the cathode is written on the right hand side. The two half cells are separated by two thick lines which represents the salt bridge.
For the cell discussed in the question; the Mn(s)/Mn^2+(aq) is the anode while the Co^2+(aq)/Co(s) half cell is the cathode.
Hence I can write; Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)
Answer:
Explanation:
Using Dalton's law of partial pressure
P total pressure = Pressure of helium + Pressure of neon + Vapor pressure of water
P = 28.3 mmHg, Pressure of helium = 381 mmHg, Vapor pressure of water at 28°C
791 mmHg - 381 mmHg - 28.3 mmHg = Pressure of neon
Pressure of neon = 381.7 mmHg
6+2=8 quarts of a new solution
0.45*6 - quarts antifreeze in <span>a solution that is 45% antifreeze
0.19*2 - </span>quarts antifreeze in a solution that is 19% antifreeze
x- concentration of a new solution
8x - quarts antifreeze in a new solution
0.45*6 + 0.19*2 = 8x
3.08=8x
x= 0.385 =38.5 %
