Suppose the moon rotating on its axis just as quickly as earth would we still always see the same side of the earth explain
Answers
Answer:If the Moon rotated as fast as the Earth would we only see one side of the Moon? ... The Moon, on the other hand, rotates once around its own axis every 28 days, and once around the Earth in that same 28 days. The end result of this combination is that the same side of the Moon is always facing the Earth
Explanation:
The moon rotates on its axis along with revolution around earth. Both time are synchronized due to the gravitational pull and tides of earth. That's why we are seeing the same side of moon.
What is gravitational pull?Gravitational force is a force by which a body attracts other body towards its centre of mass. By the gravitational pulling of earth, we are all standing on the ground.
Gravitational force depends on the mass of the body. Earth attracts its nearby objects by gravitational force and thus towards moon also. In fact if moon is quickly rotating on its own axis we would see the other side of moon.
But the fact is that the earth gravitational pulling and tides of ocean make its own gravitation also make the moon tilted slightly and assume a prolate shape. The rotation of moon is thus tidally locked and synchronized with its revolution.
Hence, moon rotates exactly once every time as it revolve around earth in a tilted axis. Thus the other side will always hide from the earth's surface.

Crude oil may contain hundreds of different types of hydrocarbons. Some examples include: Butane(C4H10) Dodecane (C12H26) Octane (C8H18) Benzene (C6H6) Many common fuels, such as gasoline and kerosene, are combinations of these substances or others. When these fuels burn, they combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
Answers
Answer:
Butane and benzene are both compounds. They contain multiple elements bonded together in a specific ratio. Kerosene and gasoline are mixtures because they are combinations of several compounds. Oxygen is an element because it is made up of only one type of atom.

Which of the following steps can be used to identify a single replacement reaction? (5
points)
O Check whether the products are salt and water.
O Check if the ions of two compounds exchange places.
o Check if one element replaces another element in a compound.
Check whether the reactants are an acid and a base.
Answers
Answer:
d
Explanation:
check if one element replaces another element in a compound
The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.
The replacement reaction can be defined as the reaction in which the highly reactive element replaced the low reactive element in the reaction and forms a compound.
The reaction has been given as:
X + AY [tex]\rightarrow[/tex] AX + Y
The X has been highly reactive than Y replaces Y in the compound and forms the compound AX.
The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

Answer:
E. potassium (K) and bromine (Br)
Explanation:
An ionic bond is formed between compounds with a large electronegativity difference between them. It is usually between a metal and non-metal.
Potassium is a true metal found in group 1 on the periodic table. Bromine is a highly electronegative non-metal which is a halogen. Potassium will lose one of its electrons which will be gained by the Bromine. The electrostatic attraction between the two species will cause the ionic bond to form. The ability of one specie willing to lose electron and the other gaining, is the main bed rock of ionic bonding.Answer:

Sort of answer, but it'll lead you in the right direction I hope.
Explanation:
I mean, ofc, the molecules or atoms or whatever the circles are can't be put together that way bc matter says so. It looks like the other diagram is showing water or gas, and if it were turning into the one on the right, then it would usually either settle into water if it was gas or become a single solid object like water. If this is gas, then it doesn't make sense, because gas particles are always separate from each other.

A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.3 0 Calculate the initial temperature of copper (Cs = 0.385 J/g 0C for copper, and 4.18 J/g 0C for water).
Answers
Answer:
The initial temperature of the metal is 84.149 °C.
Explanation:
The heat lost by the metal will be equivalent to the heat gain by the water.
- (msΔT)metal = (msΔT)water
-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C
-ΔT = 836.29/12.51 °C
-ΔT = 66.89 °C
-(T final - T initial) = 66.89 °C
T initial = 66.89 °C + T final
T initial = 66.89 °C + 17.3 °C
T initial = 84.149 °C.

Number of moles of H₂ = 13.6moles
Unknown:
Number of moles of O₂ = ?
Solution:
In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;
From the reaction equation;
2 mole of H₂ will completely react with 1 mole of O₂
13.6 moles of H₂ will completely be used up by [tex]\frac{13.6}{2}[/tex] mole of O₂
= 6.8 mole of O₂

An ionic bond
Explanation:
They are most likely going to form an ionic bond.
An ionic bond is where atoms lose/gain electrons.
It is easier for elements in the first group to lose the one electron on their valence shell and for elements in the second group to take that.

7. Compare and contrast a dilute solution of a strong acid
and a concentrated solution of a weak acid.
Answers
Explanation:
An acid is a substance that ionizes to produce excess hydrogen ion in solutions.
A concentrated acid contains a high amount of hydrogen ions in solution compared to other ions. Such solutions usually ionizes completely. A dilute solution contains a high proportion of water and with low amount of hydrogen ions. They do not ionize easily and as fast as strong acids.The sequence of bases in a DNA template strand is 5'AAAACTGTGCAT3'. What is the corresponding mRNA produced?
