Starting in 1908, while a professor at the University of Chicago, Millikan worked on an oil-drop experiment in which he measured the charge on a single electron. J. J. Thomson had already discovered the charge-to-mass ratio of the electron.
Answer:
It is basic.
Explanation:-
Given hydrogen ion concentration [H+] = 1×10^-12
Using the formula
pH = - log [H+]
= - log [ 1 x 10^-12]
= 12
Since the pH is more than 7, the chemical is basic
Nonmetallic binds are commonly
<h3>
Answer:</h3>
2.83 g/cm³
<h3>
Explanation:</h3>
- Density of a substance is the ratio of mass of the substance to its volume.
Therefore;
- Density is given by dividing mass of a substance by its volume.
- It is measure in g/cubic centimeters or kg per cubic meters.
In this case;
Density of Al = 2830 Kg/m³
We are required to convert is to g/cm³
We use the relationship;
1 g/cm³ = 1000 kg/m³
Therefore;
= 2830 kg/m³ ÷ 1000 kg/m³
= 2.83 g/cm³
Hence, 2830 kg/m³ of Aluminium is equivalent to 2.83 g/cm³
