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.
Lithium is not nearly as abundant as sodium. If sodium ion batteries that function as lithium ion ones were developed, do you think sodium cobalt oxide would still work as the electrode material?
Answer:
No, sodium cobalt oxide would not work as the electrode material
Explanation:
Sodium is a much larger cation than lithium. Remember that ion size is a very important consideration when developing a battery. The ions to be substituted must be nearly of the same size if one ion is to replace the other in a crystal.
Since sodium ions are larger than lithium ions, sodium cobalt oxide would not work as the electrode material in Lithium ion batteries.

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.

Answer:
B
Explanation:
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]

A teacher attaches two slinky springs to a fixed support. The springs are moved, as shown in the image. Wave A wave B What property of the wave does the teacher change in the movement of each slinky? amplitude,frequency, speed, or wavelength
Answer:
a changes more because it going higher
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

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.answer asap correctly for brainleist and pls give the right answer thx!
A
Explanation:
B is wrong because it talks about speed, C is wrong because it talks about direction, and D is wrong because it talks about the amount of tilt. A is correct because it's the only one that talks about the time of the orbit and the time of orbit determines the length of a year. :)

Explanation:
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.

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.
Indicate the answer choice that best completes the statement or answers the question.

how to determine the position of an element in the periodic table
Answer: An element's location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block.

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.
