Explanation:
The fossils can be found on top of mount Everest due to regional uplift of the crust.
Mount Everest is located a along a convergent margin between two tectonic plate. Due to similarity in density between the two margins, when they collide, there is tectonic build up.
Sedimentary rock layers originally at sea levels are uplifted to those tower peaks as the plate continues to grind against each other.
Most sedimentary rocks contains fossils. As the grinding continues, the uplift and deformation continues.

How many electrons does each atom have? What group is each in?
In an atom, the electron's spin around the center, also called the nucleus. The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell, three can hold a maximum of eight electrons. ( This is the answer to both questions!)

True or False: Plants don't have brains, but they still adapt to their environments.
Answer:
True
Explanation:
I just took that last year, and got a100%
True, Plants don't have brains, but they still adapt to their environments.
What is adaptation?Adaptation is a process where they are changing their nature to suit the environment.
We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.
Hence, plants have no brains, but they still adapt.

Janet is sliding a box across the floor what does she need to know to calculate the force on a box?
Answer:
She needs to know the Mass and acceleration
Janet needs to know the mass of the box and acceleration .
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

what happens to the electronegatity when you go from top to bottom on the periodic table?
Answer:
It decreases
Explanation:
As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.
Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.Determine the mass of 2.86 mole Co(NH3)6Cl3
Answer:
765 g Co(NH₃)₆Cl₃
General Formulas and Concepts:
Reading the Periodic Table of ElementsExplanation:
Step 1: Define
2.86 mol Co(NH₃)₆Cl₃
Step 2: Define conversions
Molar Mass of Co - 58.93 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol
Step 3: Dimensional Analysis
[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃
mol Co(NH₃)₆Cl₃ and mol Co(NH₃)₆Cl₃ cancel outWe are left with grams (mass)Step 4: Simplify

10. A gas sample that has a mass of 6g occupies 400 mL at 504°C and a pressure of 600 mm Hg. Calculate the gas’s density at STP.
Answer:
51 g/mol
Explanation:
Whenever you see molar masses in gas law questions, more often than not density will be involved. This question is no different. To solve this, however, we will first need to play with the combined ideal gas equation PV=nRT to make it work for density and molar mass. The derivation is simple but for the sake of time and space, I will skip it. Hence, just take my word for it that you will end up with the equation:

4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

According to the IUPAC Standards:
First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:
[tex]-CH3[/tex] is termed as methyl
As the both the methyl group( [tex]-CH3[/tex] ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.
