Answer:
Global warming is a gradual increase in the earth's temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Since the pre-industrial period, human activities are estimated to possess increased Earth’s global average temperature by about 1 degree Centigrade (1.8 degrees Fahrenheit), variety that's currently increasing by 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. Most of the present warming trend is extremely likely (greater than 95 percent probability) the results of act since the 1950s and is proceeding at an unprecedented rate over decades to millennia.
Climate change may be a long-term change within the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
Global warming occurs when CO2 and other air pollutants and greenhouse gases collect within the atmosphere and absorb sunlight and radiation that have bounced off the earth’s surface.
Normally, this radiation would escape into space — but these pollutants, which may last for years to centuries within the atmosphere, trap the warmth and cause the earth to urge hotter. That's what's referred to as the atmospheric phenomenon.
Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the danger of wildfires. Rising sea levels will cause coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas.
Forests, farms, and cities will face troublesome new pests, heat waves, heavy downpours, and increased flooding. All those factors will damage or destroy agriculture and fisheries. Disruption of habitats like coral reefs and Alpine meadows could drive many plant and animal species to extinction.
~ extracted from Global warming documentary.
Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a variety of other impacts. All of these changes are emerging as humans still add heat-trapping greenhouse gases to the atmosphere, changing the rhythms of climate that each one living things have come to believe.

Find the moles of sulfur produced, if 2.5 moles of sulfur
dioxide are used in the following chemical reaction.
SO2 + 2H2S + 2H2O + 3S
a 7.5 mol
Answer:
7.5mols of S
Explanation:
just make sure your equation is balanced, and in this case it's balanced,
so now you can do more to more ratio.
so in this case we are dealing with SO2 and S.
According to our balanced equation we have 1 mol of SO2 producing 3mols of S, i.e
1mol(SO2). : 3mols(S)
we've been asked that if we use 2.5 moles of SO2, how many moles of S will be produced?
So, this is how we can determine the number of moles of S that will be produced .
SO2 : S
1mol : 3mols(S)
2.5mols: x
we cross multiply
x=2.5×3
x=7.5mols of S.
.: if we use 2.5 mols of SO2,, 7.5mols of Sulfur will be produced

Calculate the number of copper atoms in 2.45 mole of copper
Answer:
1.48×10²⁴ Cu atoms
Explanation:
For this question you need to use Avogadro's number 6.022×10²³atoms.
2.45 moles of Cu ×[tex]\frac{6.022x10x^{23} atoms }{1 mole}[/tex]= 1.47539×10²⁴ atoms.
The moles cancel out so you are left with atoms.
Since there are 3 significant figures in the question there should be 3 significant figures in your answer, which is 1.48×10²⁴ Cu atoms.

How many grams of nickel would be electroplated by passing a constant current of 7.2 A through a solution of NiSO4 for 90.0 min
The amount of nickel that would be electroplated by passing a constant current of 7.2 A through a solution of NiSO₄ for 90 min is 11.83g.
How much charge will be deposited by equivalent mass?Equivalent mass of any substance will be electroplated by 96485 coloumb of charge.
Equivalent mass of Ni in NiSO₄ = 58.7/2 = 29.35g
So that 96485 coloumb of charge = deposited 29.35g of Ni
Also charge will be calculated by usimg the below equation as:
Q = (I)(t), where
I = current = 7.2 ampere
t = time = 90 min = 5400 sec
Q = (7.2)(5400) = 38,880 coloumb
By using both the equations of coloumb, we calculate the grams of Ni electroplated by 38,880 coloumb charge as:
Mass of Ni = (29.35g)(38,880/96,485)
Mass = 11.826 grams = 11.83g
Hence required mass of nickle is 11.83 grams.

Assuming the quantity of current passing through the zinc and copper electrolytes is the same, mass of Zinc deposited is (x/64) × 65.0 g.
What is electrolysis?Electrolysis is the decomposition of a substance known as an electrolyte when electric current is passed through its solution or molten form.
The mass of an electrolyte deposited when current is passed is dependent on the current and the charge on the ion.
In the electrolysis of copper and zinc, assuming the quantity of current passed through their solution are the same, the moles of each zinc and copper deposited will be the same since the charges on their ions are the same.
Assuming x g of copper is deposited.
molar mass of copper = 64.0 g
molar mass of Zinc = 65.0 g
moles of copper deposited = x/64
moles of zinc deposited = x/64
mass of Zinc deposited = (x/64) × 65.0 g
Therefore, the mass of Zinc deposited is (x/64) × 65.0 g.

Given the following reaction: 2NH3(g) + 3Cl2(g) → N2(g) + 6HCl(g)? How many grams of chlorine must react to produce 16 L of nitrogen gas at 1.2 ATM and 23 °C?
Consider the N₂ gas produced:
Pressure, P = 1.2 atm
Volume, V = 16 L
Gas constant, R = 0.08206 L atm / (mol K)
Temperature, T = (273 + 23) K = 296 K
Gas law: PV = nRT
Then, n = PV/(RT)
No. of moles of N₂, n
= 1.2 × 16 / (0.08206 × 300)
= 0.79 mol
According to the given equation, mole ratio Cl₂ :
N₂ = 3 : 1
No. of moles of Cl₂ needed
= (0.79 mol) × 3
= 2.37 mol
Mass of Cl₂ needed
= (2.37 mol) × (35.5 × 2 g/mol)
= 168 g

If you form 42.5g of H2O from the above reaction, how many moles of H2 were present at
the start of the reaction
Answer: 2.36 moles
Explanation:
Using 1 g/mol for the atomic mass of hydrogen and 16 g/mol for the atomic mass of oxygen, we get that the gram-formula mass of water is 1(2)+16=18 g/mol. Thus, 42.5 grams of water is the same as 2.36 moles.
From the reaction, we know that for every 2 moles of water produced, 2 moles of dihydridotin are consumed. In each mole of dihydridotin, there is 1 mole of hydrogen, meaning that 2 moles of hydrogen are consumed.
Thus, the answer is 2.36 moles.

17.93 grams of oxygen gas occupy 12.3L of space at 109.4 kPa and 15.4°C. Details about how to calculate mass can be found below.
How to calculate mass?The mass of a given gas can be calculated by multiplying the number of moles of the substance by its molar mass.
However, the number of moles of the gas must be calculated first as follows:
PV = nRT
Where;
P = pressure = 1.0796941atmV = volume = 12.3Ln = number of molesT = temperature = 288.4K R = gas law constant = 0.0821 Latm/molK1.079 × 12.3 = n × 0.0821 × 288.4
13.27 = 23.68n
n = 13.27/23.68
n = 0.56mol
Mass = 0.56 × 32
mass of oxygen gas = 17.93g
Therefore, 17.93 grams of oxygen gas occupy 12.3L of space at 109.4 kPa and 15.4°C.
