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.

A gas occupies 1.00cm^3 at STP. What volume does it occupy at 710.0 mm Hg and 55.0°C
Answer:
Final volume is 1.29cm³
Explanation:
Using combined gas law:
P₁V₁/T₁ = P₂V₂/T₂
Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of a gas.
We can solve the volume of the gas:
P₁ = 1atm at STP
V₁ = 1cm³
T₁ = 273.15K at STP
P₂ = 710mmHg * (1atm / 760mmHg) = 0.9342atm
V₂ = ?
T₂ = 55.0°C + 273.15K = 328.15K
Replacing:
1atm*1cm³/273.15K = 0.9342atm*V₂/328.15K
1.29cm³ = V₂
Final volume is 1.29cm³

What is the percent composition of Phosphorus in Li3PO3
Answer:
you will get 17.983 g of lithium for every 100 g of lithium phosphate.
Explanation:
69.7% is the percent by mass of Lithium in Li[tex]_3[/tex]PO[tex]_3[/tex]. A percent is obtained by multiplying the result by 100.
One approach to show the concentration for an element within a compound or component in a combination is as a mass percentage. The mass percentage is computed by dividing the total weight of the combination by the mass of each component and multiplying the result by 100%. The mass percent is calculated by dividing the mass that contains the compound and solute by the mass for the element or solute.
99.795g/mol = molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex]
6.94g/mol = molar mass of Li
mass percentage of Li=(molar mass of Li/molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex])× 100
=(6.94/99.7)× 100
=69.7%

The density of mercury is 13.6 g/mL. What is the mass of 3,426 mL of mercury?
Answer:
m = 46593.6 g
Explanation:
Given data:
Mass of mercury = ?
Volume of mercury = 3426 mL
Density of mercury = 13.6 g/mL
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
13.6 g/mL = m/ 3426 mL
m = 13.6 g/mL × 3426 mL
m = 46593.6 g
How can the law of conservation of
mass for a chemical reaction be expressed?
Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.

The ions S-2, Cl-1, K+, Ca+2, Sc+3 have the same total number of electrons as the noble gas argon. How would you expect the radii of these ions to vary?
Answer:
Cl^- <S^2-<Sc^3+ <Ca^2+<K^+
Explanation:
We know that ionic radius of ions decreases from right to left in the periodic table. This is because, ionic radii decreases with increase in nuclear charge. This explains why; Sc^3+ <Ca^2+<K^+.
Secondly, even though Cl^- is isoelectronic with S^2-, the size of the nuclear charge in Cl^- is larger compared to that of S^2- . Hence Cl^- is smaller than S^2- in ionic radius owing to increased nuclear attraction in Cl^-.

Explanation:
Read the reaction and the statement.
2X(g) + Y2(g) ⇌ 2XY(s)
The equilibrium constant for the chemical reaction is found to be 20 at 150 K.
If the concentration of X is 4.0 × 10-2 M, what is the concentration of the Y2 gas?
5.50 M
8.0 M
31.25 M
40.0 M
Answer:
[Y₂] = 31.25M
Explanation:
Based on the chemical reaction:
2X(g) + Y2(g) ⇌ 2XY(s)
We must define the equilibrium constant, K as:
K = 20 = 1 / [X]²[Y₂]
Where [X] and [Y₂] are the equilibrium concentrations of each gas.
If [X] = 4.0x10⁻²M:
20 = 1 / [4.0x10⁻²M]²[Y₂]
0.032 = 1 / [Y₂]
[Y₂] = 31.25M
