The climate of a place also depends upon the amount of water in the air. How do the rising temperatures around Earth affect the

amount of water in the air? A) The water in the air evaporates because the temperature of air is rising. B) There is more water in the air because the rate of evaporation increases. C) The water in the air decreases because the water on Earth starts evaporating. D) There is less water in the air because the evaporated water falls down as rain.

Answer:

B) There is more water in the air because the rate of evaporation increases

Explanation:

As the temperatures rise across the globe, the rate of evaporation also increases, resulting in more water in the air. The reason for the increased evaporation is that the ice sheets and glaciers are melting, thus there's more liquid water. The more liquid water there is, the more evaporation there will be. As the evaporation increases, there will be an increase in the formation of clouds, thus there will be more precipitation around the world, gradually leading to warmer and wetter climate.

If it takes 20.4 mL of NaOH(aq) to reach the equivalence point of the titration, what is the molarity of H2SO4(aq)? For your ans
Alik [6]

Question is incomplete, complete question is;

A 34.8 mL solution of H_2SO_4 (aq) of an unknown concentration was titrated with 0.15 M of NaOH(aq).

H_2SO_4(aq)+2NaOH(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)

If it takes 20.4 mL of NaOH(aq) to reach the equivalence point of the titration, what is the molarity of H_2SO_4(aq)? For your answer, only type in the numerical value with two significant figures. Do NOT include the unit.

Answer:

0.044 M is the molarity of H_2SO_4(aq).

Explanation:

The reaction taking place here is in between acid and base which means that it is a neutralization reaction .

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_1,M_2\text{ and }V_2  are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=2\\M_1=?\\V_1=34.8 mL\\n_2=1\\M_2=0.15 M\\V_2=20.4 mL

Putting values in above equation, we get:

2\times M_1\times 34.8 mL=1\times 0.15 M\times 20.4 mL\\\\M_1=\frac{1\times 0.15 M\times 20.4 mL\times 10}{2\times 34.8 mL}=0.044 M

0.044 M is the molarity of H_2SO_4(aq).

What is the mass of 6.02 x 10^23 atoms of arsenic?
Anvisha [2.4K]

Answer:

Mass = 74.9 g

Explanation:

Given data:

Number of atoms of arsenic = 6.02×10²³ atoms

Mass of arsenic = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022× 10²³ is called Avogadro number.

one mole =  6.02×10²³ atoms

So number of moles of arsenic are 1 mol.

Mass of arsenic:

Mass = number of moles × molar mass

Mass = 1 mol ×  74.9 g/mol

Mass = 74.9 g

Anhydrous calcium chloride removes water vapor from the air inside a container having an air-tight seal called a desiccator. Exp
OlgaM077 [116]
Hello!

The anhydrous calcium chloride (CaCl₂) is a hygroscopic substance. That means that the substance has a very high affinity with water (H₂O).

Water vapor from the air reacts with CaCl₂ to form Hydrated complexes following this reaction:

CaCl₂ + nH₂O → CaCl₂*nH₂O

In this reaction, water vapor is consumed and removed from the air, lowering the humidity of the air inside the desiccator.
