In your own words, describe how magma changes form through the rock cycle to eventually become magma again.
Answer:
Magma becomes rock after the heating process has settled.
Explanation:
Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.
The rock cycle explains the formation and breaking of the three forms of the rocks through various modes. The magma becomes rocks and magma again through the heating and cooling process.
What is magma?Magma has been the semi-hot liquid that is present in the mantle in the lithosphere of the earth. They have very high temperatures and can push through the crust in the form of volcanic eruptions.
The magma changes its form from semi-liquid to rocks and back to magma again through the rock cycle. The hot molten magma pushes through the crust, cools, and then forms rocks. These rocks after many years start melting at higher temperature or get deep down the mantle where it converts to semi-liquid again.
Therefore, the rock cycle converts the magma.

A teacher asks students to design an activity to study the formation of inherited traits. Which activity should the students design?
Answer:
The students should create a project in which they each look at a unique trait that each have (for example, detached ear lobes) and look at their parents to see if they too have this trait. To take it a step further, look at their grandparents for this trait, and ask them about their parents and if they have this trait, this could tell them whether the trait has always, been apparent within the family, if it skipped a generation, or the genetics of one parents were more dominant then the other.

Sodium Chloride is an ionic compound. Its molar mass is 58.44g. One formula unit of NaCl consists of one____, whose chemical symbol is___ and one___whose chemical symbol is___. Please help me to fill in the gaps :)
Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is [tex]Na^+[/tex] and one anion whose chemical symbol is [tex]Cl^-[/tex]
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cation is formed by the metal sodium which forms [tex]Na^+[/tex] and the anion is formed by non metal chlorine which forms [tex]Cl^-[/tex].
For a formula unit of sodium chloride, the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus
[tex]Na^+[/tex] and [tex]Cl^-[/tex] combine to form neutral [tex]NaCl[/tex]

what is the mass of the atom
Answer:
19
Explanation:
The mass of an atom is given by its mass number. This is because the mass of an atom is concentrated at the nucleus.
Mass number = number of protons + number of neutrons
Protons and neutrons are the most massive particles in any atom.
Protons are the positively charged particles in an atom
Neutrons are uncharged particles.
So, the mass number of this atom is:
Mass number = 9 + 10 = 19

Carbon Monoxide is a toxic gas that is colorless and tasteless. How many moles of CO are in 1 L of the gas at STP?
28 moles
0.045 moles
22.4 moles
0.224 moles
Answer:
0.045 moles
Explanation:
Given data:
Moles of CO = ?
Volume of gas = 1 L
Temperature and pressure = standard
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
n = PV/RT
n = 1 atm× 1L / 0.0821 atm.L/mol.K × 273 K
n = 1 atm.L / 22.41 atm.L/mol
n = 0.045 mol

How is the rock in the deep mantle similar to the rock in the parts of the mantle nearest the surface? How is it different?
Answer:
Similarity: Rocks within the mantle contain more magnesium and iron than the ones in the crust.
Difference: Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly. On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.

what are some similarities between polar and nonpolar molecules
Answer:
Explanation:
Polar bonds also often contribute to a net dipole moment of a molecule. This basically means that there are partial charges that make a molecule overall polar. One example might be water: in H20, oxygen is very electronegative, and hydrogen is less so. This means that oxygen is more negative and hydrogen is more positive. This is why water is cohesive (can stick together): The positive ends stick to the negative ends.
To solve this we must be knowing each and every concept related to polar molecule. Therefore, polar and nonpolar molecules are covalent compound.
What is polar molecule?A polar molecule is a type of chemical compound where there is an uneven distribution of electrons among the covalently bound atoms.
The term "polarity" refers to how unlike two molecules' electrical poles are from one another. If they are quite dissimilar, the species is said to be an extremely polar molecule.
Because of the more symmetrical distribution of the electrons, non-polar molecules do not have a lot of charges on their opposing sides. The fees are all offset by one another. Polar and nonpolar molecules are covalent compound.
Therefore, polar and nonpolar molecules are covalent compound.
