To get the density you would have to divide the total mass from the volume .
mass = 100g volume = 9cm 100/9 = 11.1111111 which makes the density of the object.
Centrifugation is used to separate the suspended particles in solution.
<u>Explanation:</u>
- The method of centrifugal action commonly referred to as "Centrifugation" is majorly used to effectively separate the suspended particles from the solution by means of rotating the sample at the maximum speed.
- When the samples gets rotated at the maximum speed the suspended particles settles down at the bottom and it can be filtered using the filter paper,thus resulting in the separation of suspended particles in the solution.
- However this techniques cannot be used for the substances dissolved in solution.
1. Ge
2. Fe
3. Zn
Remember, electronegativity decreases down a group (vertically) and increases across a period (horizontally) on the periodic table. :)
Answer is no
The chemical reaction between iron and oxygen in the presence of moisture or water produces a new substance, which is the rust (iron oxide). In this case, it shows a chemical property.
