Tarnish is Ag2S-silver sulfide and the oxidation state of silver is +1
Explanation:
Since the wheel moves up and down, the position that represents the potential energy is that which has the maximum height from the ground.
Potential energy is the energy at rest of a body.
It is given as:
Potential energy = m x g x h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
We can see that mass and height are directly related to the potential energy a body exerts.
The higher the wheel from ground, the higher its potential energy.

Answer:
8kJ/mol
Explanation:
since the forward reaction is -8kJ/mol, the backward reaction has the same enthalphy but reversed
The answer to this is A i think.
Barfoed's test is a concoction test utilized for identifying the nearness of monosaccharides. It depends on the diminishment of copper(II) acetic acid derivation to copper(I) oxide (Cu2O), which frames a block red hasten.
Barfoed's reagent comprises of a 0.33 molar arrangement of unbiased copper acetic acid derivation in 1% acidic corrosive arrangement. The reagent does not keep well and it is, thusly, fitting to make it up when it is really required. May store uncertainly as per a few MSDS's.
