Lee's results indicate that mass was not conserved because he did not collect the gases produced when the charcoal was burned, unlike Charlene who collected all byproducts of the burning process. Charlene's results align with the Law of Conservation of Mass which states that mass can neither be created nor destroyed, but can change form.
The apparent discrepancy between Lee's and Charlene's results arises from the way they conducted their experiments. Lee's results indicate a lower final mass because he did not collect the gas and dust released by the burning charcoal. When charcoal burns, it undergoes a chemical reaction that produces gases such as carbon dioxide and water vapour. These gases escape into the air and are thus no longer part of the 'system' being measured. As a result, the system seems to 'lose' mass, which is actually just transformed into another form and released into the environment.
On the other hand, Charlene collected all of the byproducts (including the gases) of the burning charcoal, therefore ensuring that all the matter initially present remained within the system being measured. That's why her results indicate that mass was conserved — which is consistent with the Law of Conservation of Mass stating that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time. The mass does not change shape or location in space, even during chemical reactions.

The silicon uses in :
1- Micro-chips.
2- Motherboards
3- components on nano-technologies
4- tablet
5- Phones
The explanation:
- When the silicon incorporated into electronics, They are termed as silicon wafers. It is used as a semiconductor.
- And when it combined with the other conductors this process called doping and become ideal to make transistors and be able to amplify electric signals.
That's how Silicon shape our technological reality.

Explanation:
These Rocks shown in photographs are made of different types of minerals which have properties as follows:
●The color of the rock is grey, brown and yellow after it is ground into a powder its color is streak.
● The lustre of the rock tells how shiny the rocks are.
● Other properties include hardness, texture, shape, and size.
