Answer:

Water vapor enters the atmosphere through evaporation from water bodies (oceans, seas, lakes, rivers), ice/snow cover and soil, as well as through evapotranspiration from vegetation

Explanation:

The cycle, which occurs in the troposphere, begins as the sun evaporates large amounts of water from the earth's surface and the moisture is transported to other regions by the wind. As air rises, expands, and cools, water vapor condenses and clouds develop

Answer:

0.03 mol

Explanation:

The equation relating the number of moles and number of atoms is:

Number of atoms = number of moles × 6.02 × 10²³

[6.02 × 10²³ is the Avogadro's constant and is the number of particles in 1 mole of any substance.]

By rearranging the equation, we can find the number of moles of calcium.

Number of moles = (3.01 × 10²²) ÷ (6.02 × 10²³)

Number of moles = 0.05 moles of calcium

Now the only data we know about these two elements are their Mr values, so we are going to find the number of moles of magnesium using ratio.

    Moles : Mr

0.05 mol : 40.1

           x  : 24.3

[we are going to assume that x is the number of moles of magnesium that we have to find out.]

Cross multiply the ratios.

40.1x = 0.05 × 24.3

x = 1.215 ÷ 40.1 = 0.03 mol

% composition of ethanol = 34.51%

% composition of water  = 65.49%

A material's density is defined as its mass per unit volume.

Given data:

The density of ethanol = 0.7890 g/mL

The density of water = 0.9982 g/mL

The density of mixture = 0.926 g/mL

Let the % composition of ethanol = x

Let the % composition of water = 100-x

Now density of the mixture

[tex]\frac{Mass}{Volume}[/tex]

[tex]Mass = \frac{percent \;of \;ethanol \;X \;density \;of \;ethanol \;+ \\ \;percent \;of \;water X \;density \;of \;water}{100}[/tex]

Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.

First, remember that scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

You want to add two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found.

In this case, the highest exponent is 5.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 8.6500×10³= 0.086500×10⁵

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

0.086500×10⁵ + 6.5500×10⁵= (0.086500+ 6.5500)×10⁵=  6.6365×10⁵

The theoretical amount of each product obtained are:

Mg(ClO₃)₂ + 2NaOH —> Mg(OH)₂ + 2NaClO₃

From the balanced equation above,

1 mole of Mg(ClO₃)₂ reacted with 2 moles of NaOH

Therefore,

2.72 moles of Mg(ClO₃)₂ will react with = 2.72 × 2 = 5.44 moles of NaOH

From the calculation above, we can see that a higher amount (5.44 moles) of NaOH than what was given (3.14 moles) is needed to react completely with 2.72 moles of Mg(ClO₃)₂

Therefore, NaOH is the limiting reactant

From the balanced equation above,

2 moles of NaOH reacted to produce 1 mole of Mg(OH)₂

Therefore,

3.14 moles of NaOH will react to produce = 3.14 / 2 = 1.57 moles of Mg(OH)₂

Thus, the theoretical yield of Mg(OH)₂ is 1.57 moles

From the balanced equation above,

2 moles of NaOH reacted to produce 2 mole of NaClO₃

Therefore,

3.14 moles of NaOH will also react to produce 3.14 moles of NaClO₃

Thus, the theoretical yield of NaClO₃ is 3.14 moles
