Answer:
causes day and night goes in rotate365 days goes in revolvespins goes in rotate24 hours goes in revolvecauses seasons goes in rotationgo around goes in revolveExplanation:
Earth is closer to the sun and revolves around it in about 365 days. Sentences: Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time a planet takes to revolve around the sun is called a year there for 365 days would be revolve.
It takes the earth abut 24 hours, or one day, to make one complete rotation. At the same time, the earth is moving around the sun. This is called a revolution there for 24 hours is revolve.
the spinning of the earth is called rotation therefore its rotate.
Earth rotates on its axis; this causes us to experience day and night. But Earth's axis is tilted 23.5 degrees (the angle is measured between Earth's equatorial plane and the plane in which it orbits our Sun) therefore causes day and night is rotate.
Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists therefore causes of seasons is rotate.
Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution therefore earth spins goes in revolve.

Explanation:
Functional group can be interconverted into each there by the means of suitable reagent. Functional group are responsible for the chemical and physical properties of a compound. The correct option is option D that is amine group.
What is functional group?A group of atoms forming a component of a molecule that accounts for a particular function or chemical behavior is called a functional group. There are so many functional group in organic chemistry. Functional group determine the property of a compound.
The list of functional group are as follow:
Carboxylic group COOH
Alcoholic group OH
Ammine group R-NH₂
Ketonic group R-CO_R
Aldehydic group R-CHO
Thiol group R-S-H
Cyanide group -CN
The given image represent amine group.

How do I find the Electrons of a substance? For example, there's like 10 protons & neutrons, how would I find the electrons? Please help ASAP!
Answers
Answer:the number of electrons is equal to the number of protons in a neutral atom that is. In a cation or anion atom you either gain or lose electrons. Let’s say it’s a cation +3 you lose 3 electrons. Now let’s say it’s an Anion -3 you gain 3 electrons. Hope this helps.

Why are prefixes not needed in naming ionic compounds?
A. lon charges are written as superscripts with the names of the
atoms.
B. Roman numerals are used instead of prefixes to indicate number.
C. Subscripts are used in the name to indicate number of atoms.
D. Ions combine in only one ratio.
Answers
Answer:
Ions combine into only one ratio
Explanation:
Just took test
Prefixes are not used to indicate the number of atoms when writing the chemical formula. The number of atoms are written as subscripts to their chemical symbols.
What is chemical formula?Chemical formula of a compound is used to identify a compound and distinguishes it from other compounds. A chemical formula is written from the chemical symbols of elements which constitute the compound.
The number of atoms of each element is written as the subscripts of the symbols for each atoms. For example,magnesium chloride contains one magnesium and two chlorine atoms thus, its formula is MgCl₂.
The subscripts for each atom in the formula of an ionic compound is the charge of the other atom into which it is bonded. Similarly, the formula of iron oxide containing 2 Fe and 3 O is written as Fe₂O₃.

Explanation:
When a forest burns and all that's left is some ash, most of the mass of the trees go to the atmosphere, in the form of carbon dioxide.
In a total combustion process of organic matter, the two molecules produced are carbon dioxide and water. (CO₂ and H₂O)

Explain why calcium (Ca) has a greater atomic radius than magnesium (Mg).
Answers
Answer:
Magnesium nucleus will attract the electrons more toward it and therefore, shrinking the size of the atom. Magnesium atom is smaller than Calcium atom because Calcium has more electron ( 20e− ) which will occupy more energy levels ( n=4 for Calcium versus n=3 for Magnesium)

Q 1. Element M is a metal that forms compounds of the type MX2, MX3, and MX4, where X is a Chlorine (Cl).
I) What is the expected trend in the ionic radius of M in these compounds?
II) Arrange these compounds in order of decreasing ionic radius of M.
Do not respond if u don’t know the answer. I’ll report it and u will get a warning.
Answers
Answer:
See explanation
Explanation:
The ionic radius of metal M decreases as the charge on the metal M increases. The ionic radius is generally defined as the distance between the nucleus and the outermost electron of the ion. Hence, ionic radius becomes much lesser as the magnitude of the positive charge increases.
It is obvious from the various formulae of metal chlorides in the question that the metal forms cations M^2+, M^3+ and M^4+ respectively. The order of decreasing ionic radius of the compounds is;
MX2 > MX3 > MX4
