Answer:
I ordered the tiles from left to right and top to bottom as the numbers kept increasing. The tiles were also organized based on the color and shape that they were. The tiles with the same color and shape were arranged in the same column.
Explanation:
In the modern periodic table, the elements are listed in order of increasing atomic number and elements having similar chemical properties naturally line up in the same column (group).
Based on the quantity as well as shape of each tile, arrange them in the table.
What is tile?The majority of the time, tiles are thin, square usually rectangular coverings made of durable materials like ceramic, stone, metals, baked clay, or perhaps even glass. They are typically put in place inside an arrangement to cover surfaces including tabletops, borders, floors, walls, and roofs.
In another definition, a tile is indeed a building material or a comparable object, such the rectangular game counters. The word comes taken from the Latin phrase tegula, which means a roof tile made of heated clay. Based on the quantity as well as shape of each tile, arrange them in the table.
Therefore, based on the quantity as well as shape of each tile, arrange them in the table.

Answer:
cementation
Explanation:
part of the rock cycle
The sedimentary rocks that are formed from physical/chemical process within the earth are given the general name of chemical precipitation.
What do you mean by the chemical precipitation ?Chemical precipitation is the process of turning a liquid into a solid by either making the liquid insoluble or making it very saturated.
Chemical precipitation, which starts when water moving through rock dissolves part of the minerals, creates chemical sedimentary rocks. When the water evaporates, the minerals are finally redeposited or precipitated after being moved away from their source.
A chemical compound that develops when the solution it was dissolved in, often water, evaporates and leaves the compound behind is known as a chemical precipitate.
Thus,Chemical precipitation is the process that gives rise to chemical sedimentary rocks including limestone, halite, and flint.

Which gas sample contains the most molecules ?
Answer:
CO2
Explanation:
(a) CO2; according to Avogadro's Hypothesis, they all contain the same number of particles, therefore, the heaviest molecule, CO2 (molar mass = 44), will have the greatest mass. (b) all the same; at the same temperature all gases have the same kinetic energy.
A wave that travels at the speed of light and consists of a combined electric and magnetic effect
Answer:
Electromagnetic waves
Explanation:
The description given is that of an electromagnetic wave.
Electromagnetic waves are propagated by the vibration of electrical and magnetic fields in a perpendicular direction to one another.
These waves generally travel at the speed of light. They are made up of magnetic and electric fields. They do no require a material medium for their propagationThey can pass through a vacuum.A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity
Answer:
The final velocity of the motorcycle is 64.7 m/s
Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation
Explanation:
Using the equation of motion that contains all the given values in the question: v² = u² + 2as
where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance
v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m
v² = 0² + 2 * 4.55 * 460
v² = 4186
take square root of both sides
v = 64.7 m/s
Therefore, the final velocity of the motorcycle is 64.7 m/s

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

Why the planets are arranged as they are in our solar system.
Answer:
The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets—Mercury, Venus, Earth and Mars—are terrestrial planets.

A student cut out a spiral shape from a piece of tissue paper and hung it from a string over a light bulb. Nothing happened. Next the student turned on the light. After a few seconds, the spiral began to turn above the light. Which of these best explains what happened?
Answer:
See explanation
Explanation:
Initially, when the paper is hung over the light bulb, we observe that nothing happens at all.
As time goes on, air surrounding the lamp begins to heat up. Remember that hot air is lighter and less dense than cold air. Air surrounding the lamp which has now become hotter and less dense rises and pushes on the spiral. This causes the spiral to begin to spin.

A sample of calcium oxide (CaO) has a mass of 2.80 g. The molar mass of CaO is 56.08 g/mol. How many moles of CaO does this sample contain?
0.0499
20.0
58.9
157
Answer:
A) 0.0499
Explanation:
According to the mole concept, 2.80 g of calcium oxide sample has 0.0499 moles.
What is mole concept?
According to the mole concept,mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
As per the formula for number of moles, which is mass/molar mass
number of moles of calcium oxide is:2.80/56.08=0.0499 moles.
Hence, 2.80 g sample of calcium oxide has 0.0499 moles.
