How do prevailing winds affect air temperature?

Chemistry
1 answer:
GalinKa [24]3 years ago
4 0

Answer:

Explanation:

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall

Define oxidation, reduction, and oxidation number. Describe how oxidation and reduction affect the oxidation number of an elemen
Andreas93 [3]

Answer:

Oxidation: the loss of electrons

Reduction: the gain of electrons

Oxidation number: the charge based on the number of electrons assigned to an atom as compared to the neutral atom

Explanation:

The oxidation number of a neutral atom is zero. When the atom is oxidized, it loses electrons (which have a negative charge), so the oxidation number goes up. When the atom is reduced, it gains electron (it gains negative charge), so the oxidation number goes down.

A quantity of 8.10 × 102 mL of 0.600 M HNO3 is mixed with 8.10 × 102 mL of 0.300 M Ba(OH)2 in a constant-pressure calorimeter of
victus00 [196]

Answer:

22.48°C is the final temperature of the solution.

Explanation:

Heat of neutralization of reaction , when 1 mol of nitric acid reacts= ΔH= -56.2 kJ/mol= -56200 J/mol

Moles (n)=Molarity(M)\times Volume (L)

Moles of nitric acid = n

Volume of nitric acid solution = 8.10\times 10^2 mL= 0.81L

Molarity of the nitric acid = 0.600 M

n=0.600 M\times 0.81 L=0.486 mol

Moles of barium hydroxide = n'

Volume of barium hydroxide solution = 8.10\times 10^2 mL= 0.81L

Molarity of the barium hydroxide= 0.300 M

n'=0.300 M\times 0.81 L=0.243 mol

2HNO_3+Ba(OH)_2\rightarrow Ba(NO_3)_3+2H_2O

According to reaction, 2 mol of nitric acid reacts with 1 mol of barium hydroxide .Then 0.486 mol of nitric acid will react with :

\frac{1}{2}\times 0.486 mol=0.243 mol barium hydroxide.

Heat release when 0.486 mol of nitric acid reacted = Q

= ΔH × 0.486 = -56200 J/mol × 0.486 mol=-27,313.2 J

Heat absorbed by the mixture after reaction = Q' = -Q = 27,313.2 J

Volume of the nitric solution = 0.81 L = 810 mL

Volume of the ferric nitrate solution = 0.81 L = 810 mL

Total volume of the solution = 810 mL + 810 mL = 1620 mL

Mass of the final solution = m

Density of water = density of the final solution = d = 1 g/mL

Mass=density\times Volume

m=1 g/ml\times 1620 ml=1620 g

Initial temperature of the both solution were same = T_1=18.46^oC

Final temperature of the both solution will also be same after mixing= T_2

Heat capacity of the mixture = c = 4.184 J/g°C

Change in temperature of the mixture = ΔT =(T_2-T_1)

Q=mc\Delta T=mc(T_2-T_1)

27,313.2 J= 1620 g\times 4.184 J/g^oC\times (T_2-18.46^oC)

T_2=22.49^oC

22.48°C is the final temperature of the solution.
