a mixture contains cobalt metal copper metal, and tin metal. This metal is mixed with nickel nitrate. Which metals, if any will
1 answer:
Answer:
Cobalt
Explanation:
More reactive metal displaces less reactive metal from its salt.
Reactivity of a metal is determined by its position in activity series. A metal can displace only those metals from their salts which are below than it in the activity series.
Among given, only cobalt is above than nickel in reactive series, so only cobalt will react with nickel nitrate and displaces it.
The reaction between cobalt and nickel nitrate is as follows:

Answer:
The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
Explanation:
Water potential = Pressure potential + solute potential
We have :
C = 0.15 M, T = 273.15 K
i = 1
The water potential of a solution of 0.15 m sucrose=
(At standard temperature)
The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
