What are the values for % Cl and % F, respectively, for Sample II?
horsena [70]

Answer:

Explanation:

The mass percentages of chlorine and fluorine:

  Given:

Mass of chlorine = 5.753g

 Mass of fluorine = 9.248g

Find the total of the masses given:

   Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g

% of Cl = \frac{mass of chlorine}{total mass} x 100

% of Cl = \frac{5.753}{15.001} x 100 = 38.35%

% of F =  \frac{mass of fluorine}{total mass} x 100

% of F =  \frac{9.248}{15.001} x 100 = 61.65%

A dextrose/saline aqueaout solution doctors commonly use to replace fluids in the body contains 1.75g/L NaCl and 40.0g/L dextros
qwelly [4]

<em>Mixed molarity = 0.25 M</em>

<em>Osmotic pressure solution: 6.15 atm</em>

<h3><em>Further explanation</em></h3>

Osmotic pressure is the minimum pressure given to the solution so that there is no osmotic displacement from a more dilute solution to a more concentrated solution.

General formula:

\large{\boxed {\bold {\pi \: = \: M \: x \: R \: x \: T}}}

π = osmotic pressure (atm)

M = solution concentration (mol / l)

R = constant = 0.08205 L atm mol-1 K-1

T = Temperature (Kelvin)

Mixing solution

To find the molarity of the mixed solution we can use the following formula:

Vc. Mc = V1.M1 + V2.M2

where

Mc =Mixed molarity

Vc = mixed volume

Mr. NaCl = 58.5

Mr. Dextrose = C₆H₁₂O₆ = 180

mole NaCl = gram / Mr

mole NaCl = 1.75 / 58.5 = 0.03

Dextrose mole = 40/180 = 0.22

Assuming 1 liter of solution

M mixture = mole NaCl + mole dextrose / 1 liter

M mixture = 0.03 + 0.22 / 1 L

M mix = 0.25 M

T = 25 + 273 = 298 K

The osmosis pressure of the solution becomes:

π = 0.25. 0.0825. 298 = 6.15 atm

According to this chemical reaction, which is the number of grams of Fe produced from 14 moles of H2? Fe3O4 + 4 H2 → 3 Fe + 4 H2
IRINA_888 [86]

Answer:

\boxed{\text{586 g}}

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

M_r:                            55.85  

            Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

n/mol:                  14

1. Use the molar ratio of Fe:H₂ to calculate the moles of Fe.

\text{Moles of Fe = 14 mol H$_{2}$}  \times \dfrac{\text{3 mol Fe}}{\text{4 mol H$_{2}$}} =\text{10.5 mol Fe}

2. Use the molar mass of Fe to calculate the mass of Fe

\text{Mass of Fe = 10.5 mol Fe} \times \dfrac{\text{55.85 g Fe}}{\text{1 mol Fe}} = \textbf{586 g Fe}\\\\\text{The reaction will produce $\boxed{\textbf{586 g}}$ of Fe}

The theory of plate tectonics describes the movement of the plates across the Earth's lithosphere (the crust and upper mantle) t
OlgaM077 [116]

Earth's rotation, gravity, and mantle dynamics play greater role in reshaping the land of continents and Islands.

<h3>What factors influence the size, shape and position of land?</h3>

Earth's rotation, gravity, and mantle dynamics are the forces that play a significant role in influencing the size, shape, and positioning of the different landmasses of our continents and islands. These forces are responsible for the change in shape of land masses with the passage of time.

So we can conclude that Earth's rotation, gravity, and mantle dynamics play greater role in reshaping the land of continents and Islands.
