Question 2 (3 points)
What is the empirical formula for a compound that contain 1.011 g of chromium and 0.467 g of oxygen. ?

Answers

Answer 1

Chromium oxide's empirical formula is Cr₂O₃

The simplest whole-number ratio of atoms in a compound is the empirical formula. The proportion of atoms to moles is the same. Our task then is to determine the molar ratio of Cr to O.

Cr's mass is 7.35 g.

10.74 g of chromium oxide are equal to 10.74 g of chromium and 10.74 g of oxygen.

O's mass is 10.74 g - 7.35 g, or 3.39 g.

Moles of Mg = 52.00 g Mg = 0.1413 mol Mg/7.35 g Mg = 1 mol Mg

Moles of O equal 3.39 g O to 1 mol O and 16.00 g O to 0.2119 mol O

For every 3 mol of O, there are 2 mol of Cr.

Chromium oxide's empirical formula is Cr₂O₃.

What is equilibrium in a chemical reaction?

Equilibrium in a chemical reaction refers to the point in a chemical reaction in which the rate of the formation of product from the reactants or the forward reaction is equal to the rate of formation of reactants from products or the backward reaction.

For equilibrium to be achieved in a chemical reaction the reaction must occur in a closed or isolated system.

The condition that occur in a reaction in equilibrium are described by Le Châtelier’s principle which states that for a reaction in equilibrium, the equilibrium position will shift to annul any constraint or change imposed on the system.

Considering the given reactions:

2 NH₃ (g) → 3 H₂ (g) + N₂(g) : addition of N₂ shifts equilibrium to the left

N₂ (g) + O₂(g) → 2 NO (g) : addition of N₂ shifts equilibrium to the right

The evidence to explain how advancements in technology influenced cell theory is the invention of microscopes. It has lead the way into the discovery of cells.

The magnification and resolution technology in microscopes have helped the scientists to observe the characteristics of cells and to understand the organization of the life.Cell theory is a scientific theory which was first formulated in the mid-nineteenth century. It states that the living organisms are made up of cells. All cells come from the pre-existing cells. Cells are the basic structural and organizational unit of all the organisms.Technology such as lenses, magnifying glasses, and microscopes had an impact on the development of the cell theory. Below are some examples of how such technologies contributed to the cell theory.The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke.The invention of the microscope led to the discovery of the cell by Robert Hooke. He observed a box-shaped structures, which he called “cells” as it reminded him of the cells, or rooms, when he was looking at the cork. This discovery led to the formation of the cell theory.After Robert Hooke discovered cells in cork, Anton van Leeuwenhoek in Holland made other important discoveries using a microscope. Leeuwenhoek made his own microscope lenses. His microscope was more powerful than other microscopes of that time. Leeuwenhoek’s microscope was almost as strong as modern light microscopes.

What volume of a 0.35 M NaCl solution would contain 23.0 grams of NaCl?

Answers

With 25 grams of sodium chloride, 1.2 liters of a 0.35 M solution of sodium chloride may be created.

The quantity of solute dissolved in one liter of solution is known as molarity (M).

Molarity (M) is defined as the number of moles of a solute divided by the volume of the solution in litres.

M = n / v where

M stands for molarity, n for moles, and V for volume of solution.

NaCl's molar mass is 23 g/mol plus 35.5 g/mol.

= 58.5 g/mol

Now,

Given mass/molar mass equals the number of moles (n).

= 0.427

We must now determine the solution's volume.

M = 0.35 = 0.427 / v

V is 1.2 liters

Thus, 25 grams of sodium chloride might be used to create 1.2 liters of sodium chloride solution at 0.35M.

Answers

The molar mass of the compound is 336.36mol

Molar mass defined as the mass of a sample of that compound divided by the amount of substance

Here given data is mass of sample = 132.0 g

M2 = molar mass of sample

W1 = molar mass of compound

W2 = weight of compound

One anabolic steroid is fluoxymesterone (C20H29FO3). Calculate the percent composition of carbon by mass of
fluoxymesterone.

Answers

Answer:

Percent Composition (C)  =  71.40%

Explanation:

To find the percent composition of carbon by mass, you need to (1) calculate the molar mass of C₂₀H₂₉FO₃ (using the atomic masses of each atom in the molecule), then (2) calculate the total amount of carbon in C₂₀H₂₉FO₃ (using the atomic mass of carbon), and then (3) calculate the percent composition of carbon.

(Step 1)

Atomic Mass (C): 12.011 g/mol

Atomic Mass (H): 1.008 g/mol

Atomic Mass (F): 18.998 g/mol

Atomic Mass (O): 15.999 g/mol

Molar Mass (C₂₀H₂₉FO):

20(12.011 g/mol) + 29(1.008 g/mol) + 18.998 g/mol + 3(15.999 g/mol)

=  336.447 g/mol

(Step 2)

Atomic Mass (C): 12.011 g/mol

Total Mass (C): 20(12.011 g/mol) = 240.22 g/mol

Express your answer to two significant figures and include the appropriate units.

Answers

The difference between the ideal pressure and the pressure calculated by the Van Der Waal equation is 2.08 atm.

What is the pressure?

In this problem, we are mandated to obtain the pressure both by the use of the ideal gas equation and then the use of the Van der Walls equation.

Using the idea gas equation;

PV = nRT

P = nRT/V

P = pressure

V = volume

n = number of moles

T = temperature

R = gas constant

P = 1 * 0.082 * (24 + 273)/0.5

P = 48.7 atm

Using the Van Der Wall equation:

P = RT/(V - b) - a /V^2

P = 0.082 * 297/(0.5 - 0.03219) - 1.345/(0.5)^2

P = 24.354/0.46781 - 1.345/ /0.25

Answers

The density of 4.00 mL x 10⁻² mL of bromine (liquid) weighing 0.1249 g is 3.1225 g/mL.

Density of a liquid is defined as the mass of the substance per unit of its volume. Density is equal to the mass divided by the volume of any liquid. It is denoted by a Greek letter ρ. It is given by -

                                               ρ = m

                                                      v

where,

ρ = density

m = mass

v = volume

To calculate the density of bromine liquid,

We use,

         Density =   mass    

                           volume

         Density =  0.1249   g

                         4.00 x 10⁻² mL
