I think the answer is x axis
The chemical equation in this case is given by:
Zn (2+) + 2e (-) ------> Zn
It can be noted that 1 mole of Zn is produced by 2 Faraday of electricity.
For 29.1 moles,
Total charge required = 2*29.1 = 58.2 F
But, 1F = 96500 C
Then,
Amount of charge required = 96500*58.2 = 5,616,300 C
Answer: C
1054 g
Explanation:
Given that the object is in the shape of semi sphere with diameter of 8.2cm. And density of 7.3g/cm^3.
From definition of density,
Density = mass/volume
Volume of a half - sphere = 2/3πr^3
Volume = 2/3 × 3.143 × 4.1^3
Volume = 144.35 cm^3
Let make mass the subject of formula
Mass = Density × volume
Mass = 7.3 × 144.35
Mass = 1053.74g
The mass of the paperweight, in grams is 1054
