Answer:
Albedo
Explanation:
Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather. The cause of this is the reflectiveness of the surface of the Earth at that point (the albedo) and the angle that the sun's rays strike it at. A field covered with snow and ice is going to be much more reflective than a black top asphalt parking lot. As such the parking lot absorbs much more shortwave radiation from the sun and gets much warmer.
The uneven heating of Earth caused by the Sun craetes the difference in the atmosphere pressure and the volume of gasses present in atmosphere.
What is uneven heating of Earth?The uneven heating in the atmosphere disturbs the climatic conditions as there are some areas which are cold and some are hot then before and also changes the volume and pressure.
The change in the volume and the pressure results in the flow of the upward flow of the current air which is the main cause of thunder storm and some other climatic disaster can also happen.
Therefore, uneven heating of Earth caused by the Sun craetes the difference in the atmosphere pressure and the volume of gasses present in atmosphere.

how to fix/ balance this chemical reaction?
The balanced equation
2Al(NO₃)₃ + 3FeCl₂ ⇒ 3Fe(NO₃)₂ + 2AlCl₃
Further explanationGiven
Reaction
Al(NO₃)₃ + FeCl₂ --> Fe(NO₃)₂ + AlCl₃
Required
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 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.

Please mark as Brainliest!!!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]

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 %.

The empirical formula : C₁₀H₂₀O
Further explanationGiven
Combustion of menthol
Required
The empirical formula
Solution
Mass of CO₂ produced : 0.449 g
mass C = 12/44 x 0.449 = 0.122
Mass water produced : 0.1840 g
Mass H = 2.1/18 x 0.1840 = 0.02
Mass O in menthol :
=mass sample - (mass C+mass H)
= 0.1595 - (0.122+0.02)
= 0.0175
Mol ratio C : H : O in sample :
= 0.122/12 : 0.02/1 : 0.0175/16
= 0.01 : 0.02 : 0.001
= 10 : 20 : 1
