Describe in your own words how the earth's layers were formed.
Answers
The layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth. After a long duration, a new layer is spread over the older layer, and so on.
What are the different layers of the earth?The different layers of the earth are as follows:
The Inner Core: This is the first layer from the center of the earth. The Outer Core: It is found after the inner core. The Mantle: It is the middle layer of the earth. The Crust: It is the outermost layer of the earth.The above-mentioned layers of the earth were formed with the impact of the building blocks of the earth that are remarkably known as Planetesimals, collided, and collapsed.
During that time, the hardest elements like nickel, iron, etc. constitute the core while the lighter elements like carbon, oxygen, silicon, etc. play an essential role in the formation of crust and mantle.
Therefore, the layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth.

what kind of bonds involve a transfer of electrons? what kind of bond involves sharing of electrons?
Answers
Answer:
While covalent bonding involves sharing electrons between two atoms, ionic bonding involves the complete transfer of electrons from one atom to another, creating positive and negative ions. These ions are then held together by the attraction between their opposite charges.

Contrast and compare:
a) ionic and covalent bonding
Answers
Answer:
Ionic bonds - an intramolecular force exist in a nonmetal and metal compounds such as NaCl. The Na donate 1 electon to Cl to complete its octet rule.
Covalent bond - an intramolecular force exist in a nonmetal and nonmetal compounds such as bonds O2, Cl2, CO2, sugar, proteins and most of organic compounds and biomolecules by sharing electrons to bond.
There are two types of covalent bonds: polar and nonpolar. Polar bond is a bond between two different nonmetal atoms of different electronegativities. While nonpolar bond is a bond between the same atom or two differenct atoms of the same electronegativities (if there is). Their electronegativities pull will cancel so that their overall polarity is zero.

A very hot cube of copper metal (32.5 g) is submerged into 105.3 g of water at 15.4 0C and it reach a thermal equilibrium of 17.3 0 Calculate the initial temperature of copper (Cs = 0.385 J/g 0C for copper, and 4.18 J/g 0C for water).
Answers
Answer:
The initial temperature of the metal is 84.149 °C.
Explanation:
The heat lost by the metal will be equivalent to the heat gain by the water.
- (msΔT)metal = (msΔT)water
-32.5 grams × 0.365 J/g°C × ΔT = 105.3 grams × 4.18 J/g °C × (17.3 -15.4)°C
-ΔT = 836.29/12.51 °C
-ΔT = 66.89 °C
-(T final - T initial) = 66.89 °C
T initial = 66.89 °C + T final
T initial = 66.89 °C + 17.3 °C
T initial = 84.149 °C.

The chemical equation below shows the amount of the reactants used and the amount of only one of the products formed. How much water (H2O) should be formed in this chemical reaction? CH4 mass 4 + 2O2 mass 16 CO2 11 + 2h2O mass ?
Answers
Answer:
CH4 + 2O2 → CO2 + 2H2O
Explanation:
This is all i could come up with im sorry.
The amount of water formed in the given chemical reaction is 9 grams.
What is Stoichiometry?Stoichiometry is the calculation for the determination of the relative amount of reactants and products in chemical reactions. Stoichiometry is based on the law of conservation of mass where the total mass of the reactants in reaction equals the total mass of the products.
If the quantity of one reactant is known and the quantity of the product can be determined empirically, then the quantity of the other reactants can be calculated.
Given chemical equation is:
CH₄ + 2O₂ [tex]\longrightarrow[/tex] CO₂ + 2H₂O
16g 32g 44g 32g (from their molecular masses)
The amount of methane, oxygen, and carbon dioxide is 4g, 16g, and 32 g respectively.
16g of methane react with oxygen = 32g
4g of methane will react with oxygen = 8g
It means here methane is the limiting reagent as the given amount of oxygen is more than reacted one. So CH₄ will decide the amount of water.
16g of methane produces water = 32g
Then 4g of methane will produce water = (32/16) × 4 = 9 g
Therefore, 9 grams of water should be formed in this reaction.

How can air quality be fine on one day and hazardous on the next? What
are some things that can cause a rapid change in air quality? *
Answers
Answer:
Air Current
Explanation:
Say I am in California and there is a massive fire next to me but not close enough to me to really see the fire and the next day I see no fire but theres a ton of ash in the sky, this can be due to the wind current taking the smoke from the fire into my direction and that smoke falling in my area. So basically a wind current can take the smoke from a fire into another destination and cause a rapid change in air quality in a day.

Air is trapped in a cylinder fitted with a piston that occupies 150.5 mL at 1.12 atm pressure. What is the new volume when the piston is depressed, increasing the pressure by 15%?
Answers
Answer:
New volume V2 = 120.4 ml
Explanation:
Given:
Pressure P1 = 1.12 atm
New pressure P2 = 1.12[1+0.25] = 1.4 atm
Old volume V1 = 150.5 ml
Find:
New volume V2
Computation:
P1V1 = P2V2
(1.12)(150.5) = (1.4)(V2)
V2 = 120.4 ml
New volume V2 = 120.4 ml
