When light waves hit ice, most of them bounce off and radiate back into space, hence, ice is best described as a reflective surface.
What is a Reflective surface?A reflective surface is one which can cause incident light to bounce back (reflection).
According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident light reflects off the ice surface.
Therefore, the ice surface is best described as a reflective surface.

Which answer best describes why water dissolve most salts? Water is polar and salts form ions in solution. Water is nonpolar and salts form ions in solution. Water has the same density as salt Water has a different density than salts
Answer: Water is polar and salts form ions in solution.
Explanation:
According to the concept of “Like dissolves like”, the polar solutes dissolve in polar solvents, and non-polar solutes dissolve in non-polar solvents.
Water being a polar solvent due to large electronegativity difference between hydrogen and oxygen is able to interact with the ions of the solute.
As water molecules are also polar in nature. So, oppositely charged ions interact with each other and dissolve in it.
Water can form hydrogen bonds with most of the substances and hence dissolve them . Thus water is considered as a universal solvent.
Answer: Water is polar, and salts form ions in solution

What process is required for minerals to crystallize from magma
Answer:
Chemical differentiation
Explanation:
The process by which minerals crystallize out of magma is termed chemical differentiation. Some times, it is referred to as magmatic differentiation.
Minerals have different properties and at certain environment, it comfortable for the settle out of magma. Some minerals can crystallize out at very high temperature. Some will form at medium temperature whereas, some are low temperature minerals. Based on the properties of the minerals in a melt, a minerals will differentiate at various temperature and pressure regimes.2. Which state of matter will take both the volume
and shape of the container that holds it?
A. gas
B. ice
C.liquid
D. Solid
Answer:
The answer would be C) a liquid.
Explanation:
If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.

A molecule's shape greatly influences the polarity of the compound, the molecular structure has an impact on molecular characteristics. The shape of a molecule affect the molecule's function. Therefore, option B is correct.
What is molecule ?Based on the environment, the term may or may not include ions that meet this requirement. A molecule is a collection of two or more atoms held together by the attractive forces known as chemical bonds.
Molecule shape play a key role in anticipating how one molecule may interact with another, as well as in determining macroscopic features like melting and boiling points.
Polar substances have higher boiling and melting temperatures, tend to dissolve in other polar compounds, and can either form solids or liquids.
Thus, option B is correct.

What can you make with molecules ??
Answer:
Read this passage from Through the Looking-Glass.
She looked at the Queen, who seemed to have suddenly wrapped herself up in wool. Alice rubbed her eyes, and looked again. She couldn't make out what had happened at all. Was she in a shop? And was that really—was it really a SHEEP that was sitting on the other side of the counter? Rub as she could, she could make nothing more of it: she was in a little dark shop, leaning with her elbows on the counter, and opposite to her was an old Sheep, sitting in an arm-chair knitting, and every now and then leaving off to look at her through a great pair of spectacles.
“What is it you want to buy?” the Sheep said at last, looking up for a moment from her knitting.
“I don't QUITE know yet,” Alice said, very gently. “I should like to look all round me first, if I might.”
“You may look in front of you, and on both sides, if you like,” said the Sheep: “but you can't look ALL round you—unless you've got eyes at the back of your head.”

Newton Second Law of Motion, a = F/m tells us that acceleration (a) can be increased by _-
Answer:
Increasing the force
Explanation:
From Newton's second law of motion, we understand that force is a product of mass and acceleration.
Force = mass x acceleration.
Also, force is directly proportional to acceleration. The more the force applied on a body, the higher the acceleration it produces.
Mass is inversely proportional for force.
A student added white crystals to a clear liquid. The crystals dissolved in the liquid. After a few seconds, the liquid became quite warm and then turned bright red in color. The first indication that a chemical change was taking place could be observed when----
Answer:
Is when there is an increase in the temperature of the liquid
Explanation:
Increase in temperature of the liquid is an indication that chemical change occur because chemical change occur through process of chemical reaction and it involve when two or more substances combine together to form new substances which is as a result of change in chemical composition. The crystals dissolved in water to form another new solution and it became warm and this indicate a chemical change, new substances are formed as a result of increase in temperature.

Answer:

Explanation:
Answer:
They will be the same because amplitude doesn't affect speed. A physics teacher attaches a slinky to the wall and begins introducing pulses with different wavelength. The denser the medium at the compression, the greater the amplitude of the wav

Iron is extracted from iron oxide in the Blast Furnace: Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2
a) Calculate the maximum theoretical mass of iron that can be made from 100g
of iron oxide.
b) In the reaction, only 65 g of iron was made. Calculate the percentage yield.
a. mass of iron = 69.92 g
b. percent yield = 93%
Further eplanationPercent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
a.
Reaction
Fe₂O₃+3CO⇒2Fe+3CO₂
MW Fe₂O₃ : 159.69 g/mol
mol Fe₂O₃
[tex]\tt \dfrac{100}{159,69}=0.626[/tex]
mol Fe₂O₃ : mol Fe = 1 : 2
mol Fe :
[tex]\tt \dfrac{2}{1}\times 0.626=1.252[/tex]
mass of Fe(Ar=55.845 g/mol) :
[tex]\tt 1.252\times 55.845=69.92~g[/tex]
b.
actual yield = 65 g
theoretical yield = 69.92 g
percent yield :
[tex]\tt =\dfrac{65}{69.92}=0.93=93\%[/tex]
The melting point of matter is the temperature at which it changes from a:
Answer:
[tex]\boxed {\boxed {\sf Solid \ to \ liquid}}[/tex]
Explanation:
When heat is added to matter, the temperature rises. The average kinetic energy also increase and the matter melts.
When matter melts, it turns from a solid to a liquid. So, the melting point of matter is the temperature where it changes from the solid state of matter to the liquid state of matter.

why water can be consider as an acid as well as base .explain briefly
why do humans pump water from underground?
Answer:
Most wells do not get their water from underground rivers, but instead get the water from aquifers. Aquifers are layers of rock and soil with water flowing through their small pores. ... New water, such as from rain or melting snow, drips down into the ground through the pores and cracks in the rocks and soil.
Explanation:
Answer:
Pumping can affect the level of the water table. Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.
Order the density of the layers of the Earth from lowest density to highest
