what kind of plates?
Explanation:
you didn't put enough info
Answer:
Diverge means when the plates go in diffrent directions
Explanation:
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

10. the answer is not D , I know for a fact
A student asks a class the following question, “Polyethylene has a relatively short formula (C2H4) while nylon has a long formula (C12H22N2O2). However, in a toothbrush, the handle is relatively long while the bristles are relatively short. How is this possible?”
Choose the explanation below that best responds to the student’s question.
A
Molecules are so small that they cannot be seen with a naked eye. Therefore, being a slightly bigger molecule on that scale will not influence how big the part of the toothbrush is.
B
In a toothbrush, the polyethylene chain is most likely a longer chain of molecules than the nylon chain, making the handle longer than the bristles.
C
Polyethylene is used for the bristles and nylon is used for the handle, because the size of the molecule does determine the size of the object being built by the molecules.
D
Polyethylene has a short formula, but it makes a long chain. Nylon has a long formula, but it is fat, not long. That is why the nylon bristles are short while the handle is long and thin.

Give reasons for the following.
(a)Aluminium foils are used to wrap food items.
(b)Immersion rods for heating liquids are made up of metallic substances.
(c)Sodium and potassium are stored in kerosene.
4. What is the nature (acidic or basic )of the following oxides ?a.Magnesium oxide (b) Sulphur dioxideGive reason foryour choice.
5. When a copper metal is exposed to moist air for a long time,then a green coating is formed on its surface .What is the green material formed on its surface. Support your answer with word equation.Is it acidic or basic in nature.
PLEASE HELP ME !!!!
Answer:
A. oxygen
B. chlorine
2. iodine
(a) because aluminium is a soft malleable metal. it can be made to in sheets to form thin wrapping sheets. also, it does not react with food items.
(b) because metals are good conductors of heat and electricity. the immersion rod needs electric supply to get heated and to heat liquids.
(c) they're kept in kerosene to keep them from coming in contact with oxygen and moisture as they react to form their hydroxides.
4. Magnesium is a metal. Metals react with oxygen to form metallic oxides. So Magnesium oxides are basic in nature. But nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature. Nonmetallic oxides react with water to form acids. Therefore, Sulphur dioxide is acidic in nature. Magnesium oxide is basic in nature.
5. Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide. It's acidic in nature.

What is relative mass of an atom
Answer:
Explanation:
The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes - because if there is much more of one isotope then that will influence the average mass much more than the less abundant isotope will.

Which wind blows cool air inland during the day? _______
Which wind blows cool air toward the sea at night? _______
Which winds blow steadily from specific directions and over long distances? _________
Answer: hot air
hot air
cool air
Explanation:
The wind blows cool air inland during the day is sea breeze.
The wind blows cool air toward the sea at night is land breeze.
The winds blow steadily from specific directions and over long distances are global winds.
What are the global winds ?The term global wind is defined as winds that occur in belts that go all around the planet. Earth is hottest at the Equator and gets cooler toward the poles.
Global winds are winds that blow steadily from specific directions over long distances. Warm air rises at the equator and sinks at the poles, causing winds to blow from the poles to the equator at the earth's surface.
In a sea breeze the cold air travel from sea towards land during daytime and in a land breeze the cold air travel from land towards sea during night time.
Thus, The winds blow steadily from specific directions and over long distances are global winds.

magnesium reacts with oxygen and forms magnesium oxide , for example
Answer: When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide, which is a compound. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.
