Answer:
The distance the plane flies.
Explanation:
This is the dependent (outcome) variable because it is changing depending on the number of paper clips that are added to the plane.
If you follow the octet rule, you know that an element must have 8 outside (or valence) electrons to be energetically favorable.
In CCl4, the carbon molecule forms four bonds; one for each chlorine atom. Each bond contains 2 electrons, so it is satisfied.
In PCl3, Phosphorous forms only 3 bonds with chlorine, which means in order to have 8 valence electrons, it also has a lone pair of electrons, not bonded with chlorine.
Now, in CCl4, picture the shape of the molecule like a plus sign, with the carbon in the middle and the chlorine at the four ends. It is symmetrical, and therefore is nonpolar.
In PCl3, the lone pair electrons <em>push</em>, so to speak, the 3 chlorine atoms away, making a T-shaped molecule. Since the chlorine is more electronegative than carbon, the molecule is unbalenced, making it polar.
Answer:
We are in Tropical Rainforests.
Explanation:
Biome is basically an ecological region of earth that has specific type of flora and fauna (plants and animals). Every biome has specific abiotic factors like specific climate, temperature, geology, vegetation, soils and relief.
There are total 8 biomes in the world
- Desert
- Grassland
- Temperate Boreal Forest
- Chaparral
- Tropical Savanna
- Tropical Rainforest
- Tundra
- Temperate Deciduous Forest
Now in our question, we have been given some conditions and are asked to identify the biome. The annual precipitation is about 300 cm and the average temperature is around 25 degrees Celsius.
Now, if we study the characteristics of all these biomes, it is very simple to identify that the biome is Tropical Rainforest.
Important characteristics of Tropical Rainforest:
- They receive more than 200 cm of rain each year.
- The temperature of the biome is between 20 degree Celsius and 25 degree Celsius during the whole year.
- Around 50 percent of the animal specie of the world are found here.

It's very dangerous to go that deep into the ocean due to the water pressure and the coldness, no human can physically comprehend it, so if you do end up diving that deep into the ocean, you will suffocate, crush to death, or freeze very quickly.
