Answer:
Brittle, Poor Conductors, Non-Malleable
Explanation:
Non-metals are the opposite of metals; they have opposite properties.
Metals are ductile, malleable, conductive, and shiny, while nonmetals are the opposite.
Answer: The formation of a gaseous product is indicated by an UPWARD ARROW in a chemical reaction.
Explanation:
A chemical reaction is defined as the process whereby chemical bonds between atoms of
substances known as reactants are either formed or broken leading to the formation of products. New substances are usually formed during a chemical reaction. The following are features of chemical reaction:
--> Evolution of gas
--> Formation of a precipitate
--> Change in color
--> Change in temperature
--> Change in state and
--> Formation of new substances.
Some chemical reactions takes place with the evolution of gas. This can be seen in the reaction of Zinc metal with hydrochloric acid. Hydrogen gas is EVOLVED with the formation of zinc chloride.
UPWARD ARROW in a chemical reaction indicates the evolution of a gas. It appears only on the product side and is written next to the gaseous product.
The square of the orbital period of mercury is 7744
<h3>How to determine the square of the orbital period?</h3>
The square of a value (x) is calculated by:
Square = x²
The orbital period of mercury is:
orbital = 88 days
So, the square is:
Mercury = 88²
Evaluate
Mercury = 7744
Using the same formula for the other satelite objects, we have:
- Venus = 225² = 50625
- Earth = 365² = 133225
- Mars = 687² = 471969
- Jupiter = (12 years)² = 144 years²
- Saturn = (29 years)² = 841 years²
- Uranus = (84 years)² = 7056 years²
- Neptune = (165 years)² = 27225 years²
When the unit is not stated, the orbital period is in days

One important example of computer simulation is called molecular modeling. Scientists can use it to test or discover new drugs that might help treat diseases. This method allows scientists to predict what will happen when they introduce a molecule, such as a new medicine, into the human body.
