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").

Balanced equation
Solution
Give a coefficient
aAl(NO₃)₃ + bFeCl₂ --> Fe(NO₃)₂ + cAlCl₃
Make an equation
Fe, left=b, right=1⇒b=1
N, left=3a, right=2⇒3a=2⇒a=2/3
Cl, left=2b, right=3c⇒2b=3c⇒2.1=3c⇒c=2/3

How do we know that caramelizing sugar is a chemical change?
It involves dissolving sugar in water.
It changes the state of sugar from a solid to a liquid.
It separates sugar fromn a sugar solution.
It changes the sugar's color.
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
caramel is the product of the sugar and hot water
Answer:
D It changes the sugars color
Explanation:
Because the change of color is a chemical change.

How does the electron arrangement change moving vertically down a group?
Answer:
Electrons arrangement change is almost constant down the group, hence nuclear charge is almost constant.
But the energy levels on which electrons are arranged increase down the group, hence shielding or screening effect increases.
What is the percent of Nitrogen in NH3?
Answer:
82.244%
Explanation:
The mass percent is an important method which is used to calculate the concentration of a solution. The mass percent of nitrogen in NH₃ is 82.2%.
What is mass percentage?The mass percentage of a particular component in a compound can be defined as the ratio of the mass of the particular component to the total mass of the compound.
The equation which is used to calculate the mass percentage is:
Mass percentage = Mass of the component / Total mass of the compound × 100
or
The mass percentage is also calculated as:
% Mass = Mass fraction × 100
Here the mass of 'N' = 14.00 g
The molar mass of NH₃ = 17.031 g/mol
% Mass of 'N' = 14.00 / 17.031 = 0.82
0.82 × 100 = 82.2 %
Thus the mass percentage of nitrogen is 82.2 %.

Analyze. This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys the laws of Conservation or energy
Answer:
See explanation
Explanation:
If heat is given out in a reaction, then that reaction is exothermic. If heat is absorbed in a reaction, then that reaction is endothermic.
Hence, if heat is given out, the reaction is exothermic. The heat given out does work on the surrounding thus the laws of conservation of energy are obeyed.
Answer:
The reaction is exothermic.

Which subatomic particle can be found revolving around the nucleus?
proton
neutron
electron
Answer : The correct option is, electron.
Explanation :
As we know that,
An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.
The electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
According to the question, the electron subatomic particle found revolving around the nucleus.
Hence, the correct option is electron.

What is the mass in grams of
0.625 mol Ba(NO3)2?(please show work)
Answer:
Explanation:
Using the formula as follows: mole = mass/molar mass
Molar mass of Ba(NO3)2
= 137 + (14 + 48)2
= 137 + 124
= 261g/mol
Mole = mass ÷ molar mass
0.625 mol = mass/261g/mol
mass = 0.625 × 261
mass = 163g
An 18.0 g piece of an unidentified metal was heated from 21.5 °C to 89.0 °C. If 789.75 J of heat energy was absorbed by the metal in the heating process, what was the identity
of the metal?
Answer: The metal is Calcium.
Explanation:
To calculate the specific heat of substance during the reaction.
[tex]q=m\times c\times \Delta T[/tex]
where,
q = heat absorbed = 789.75 J
c = specific heat of metal = ?
m = mass of substance = 18.0 g
[tex]\Delta T_f[/tex] = final temperature - initial temperature = [tex](89.0-21.5)^0C=67.5^0C[/tex]
Now put all the given values in the above formula, we get:
[tex]789.75J=18.0g\times c\times 67.5^0C[/tex]
[tex]c=0.65J/g^0C[/tex]
As specific heat is characteristic of each metal and thus the metal is calcium which has specific heat of [tex]0.65J/g^0C[/tex]

how is the potential (voltage) of a redox reaction determined using the reduction potential chart calculate the voltage for the equation in 3(a)
Answer:
Oxidation half reaction is written as follows when using using reduction potential chart
example when using copper it is written as follows
CU2+ +2e- --> c(s) +0.34v
oxidasation is the loos of electron hence copper oxidation potential is as follows
cu (s) --> CU2+ +2e -0.34v
Explanation:
Answer:
The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. ... The cell potential (Ecell) is measured in voltage (V), which allows us to give a certain value to the cell potential.
