This is science.
First and best answer gets 5 stars, a thanks, and a brainliest!

Answers

Doing this because I know I'm kickass at Chemistry.

One source would be human emissions. As humans, we use a lot of machines (like power plants) that produce large amounts of carbon dioxide into the atmosphere. The ocean also produces a lot of carbon dioxide via the evaporation cycle. Polluted waters eventually will go into the atmosphere. Volcanoes, even when not erupted, emit a lot of carbon dioxide as well. Dormant underground magma releases carbon dioxide through the Earth's pores, and even when a volcano erupts, it produces carbon dioxide as well.

Answers

Radiation happens when heat move as energy wave called infrared wave directly from its source to something else .
well what happens is radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. this is how the heat from the sun gets to earth. in fact, all hot things radiate heat to cooler things. when the heat waves hits the cooler thing,they make the molecule of the cooler object speed up. hopefully this is the correct answer

List four greenhouse gases in the atmosphere. For each gas, describe its prevalence in the atmosphere, its natural sources, its human-induced sources, and how its concentration in the atmosphere might be changing.

Answers

Answer: Carbon Dioxide, Methane, Nitrous Oxide and Fuorinated Gases

Explanation:Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere (or "sequestered") when it is absorbed by plants as part of the biological carbon cycle.

Methane (CH4): Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.

Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.

Fluorinated gases: Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred to as High Global Warming Potential gases ("High GWP gases").

Answers

Answer: [tex]Pb(NO_3)_2(aq)+2NH_4Cl(aq)\rightarrow PbCl_2(s)+2NH_4NO_3(aq)[/tex] .

The insoluble product is lead (II) chloride.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

[tex]Pb(NO_3)_2(aq)+2NH_4Cl(aq)\rightarrow PbCl_2(s)+2NH_4NO_3(aq)[/tex]

The insoluble product is lead (II) chloride.

5. The chemical formula for rust is Fe203. If the total mass of rust on a 1967 Chevy corvette is 190 kg, how many moles is that?

Answers

Answer:

1. 0.0033 moles of water.

2. 270g of water

3. 12.8g NaCl

4. 6.72g NaHCO3

5. 1190moles Fe2O3

Explanation:

To convert moles to grams or vice versa we require tu use molar mass of the substance as follows:

1. Molar mass water: 18g/mol

0.060g * (1mol / 18g) = 0.0033 moles of water

2. Molar mass water: 18g/mol

15 moles H₂O * (18g / 1mol) = 270g of water

3. We can assume all sea salt is NaCl -Molar mass: 58.44g/mol-

750g NaCl * (1mol / 58.44g) = 12.8g of NaCl

4. Molar mass NaHCO₃: 84g/mol:

0.080mol * (84g/mol) = 6.72g NaHCO3

5. Molar mass Fe2O3: 159.69g/mol:

190kg = 190000g * (1mol / 159.69g) = 1190moles Fe2O3

The term "alchemy" refers to early pseudoscientific attempts to transform common
elements into more valuable elements (such as lead into gold), For one kind of atom to
become another kind of atom, which particle(s) of the atom need to be expelled or gained?
Proton
Electron
Neutron
Quantum Particles

Answers

Answer: The correct answer is option B. electron.

Explanation:

There are 3 subatomic particles:

Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.Protons: They carry positive charge and are present inside the nucleus of an atomNeutrons: They does not carry any charge and are present inside the nucleus of an atom.

An atom forms an ion, when it looses or gains an electron.

When an atom looses electron, it form a positive ion known as cation.When an atom gains electron, it form a negative ion known as anion.

Hence, the correct answer is option B. electron.

The particle(s) of the atom that is needed to be expelled or gained in an alchemy process which involves transformation of one element into  valuable elements or atom to another is B:Electron.

Alchemy can be regarded as branch of  philosophical and protoscientific tradition that is traceable to China,  and Europe. In the process of transformation of one element to another useful element or compounds , there is usually transfer of electron.

Electronegative element like chlorine usually gain electron and are anion, while electropositive elements like potassium will loose electron( cation) all involves the transfer of electron.

Therefore, option B is correct.

The quarter at which the moon will be one(1) week after the new moon is up in the sky is the first quarter. And at the first quarter the moon will be in its " waning gibbous " phase.

The waning gibbous phase is the stage in the new moon cycle where only one half ( 1/2 ) or 50% of the moon is lit and the moon will remain in this stage up until 21 days.

Hence we can conclude that the image that shows the phase of the moon one week after the new moon is Image G.

How many oxygen atoms are in 163 g of aluminum sulfate? 

Answers

Answer:

3.44 × 10²⁴ atoms of oxygen

Explanation:

Step 1: Calculate the moles corresponding to 163 g of Al₂(SO₄)₃

The molar mass of Al₂(SO₄)₃ is 342.15 g/mol.

163 g × 1 mol/342.15 g = 0.476 mol

Step 2: Calculate the molecules in 0.476 moles of Al₂(SO₄)₃

We will use Avogadro's number: there are 6.02 × 10²³ molecules of Al₂(SO₄)₃ in 1 mole of Al₂(SO₄)₃.

0.476 mol × 6.02 × 10²³ molecules/1 mol = 2.87 × 10²³ molecules

Step 3: Calculate the atoms of O in 2.87 × 10²³ molecules of Al₂(SO₄)₃

According to the chemical equation, the molar ratio of Al₂(SO₄)₃ to O is 1:12. The atoms of O are 12/1 × 2.87 × 10²³ = 3.44 × 10²⁴.
