Answers

Answer 1

For the following molecules:

E. Water: inorganic (H₂O), f. Carbon dioxide (CO₂): inorganic, g. Fats: organic (C, H, O).

h. Sugar: organic (C, H, O).

i. Salts: inorganic.

j. Protein: organic (C, H, O, N, S).

k. Oxygen gas (O₂): inorganic.

l. DNA: organic (C, H, O, N, P).

E- . water: Water (H₂O) is an inorganic molecule composed of two hydrogen atoms (H) bonded to one oxygen atom (O). It does not contain carbon and is classified as inorganic.

f. carbon dioxide (CO₂): Carbon dioxide is an inorganic molecule consisting of one carbon atom (C) bonded to two oxygen atoms (O). It does not contain hydrogen and is classified as inorganic.

g. fats: Fats, also known as triglycerides, are organic molecules composed of carbon (C), hydrogen (H), and oxygen (O). They consist of glycerol and fatty acids and are essential components of living organisms.

h. sugar: Sugar is a broad term that can refer to various organic molecules, such as glucose, fructose, and sucrose. These molecules are composed of carbon (C), hydrogen (H), and oxygen (O) atoms. Sugars are vital sources of energy in living organisms.

i. salts: Salts are inorganic compounds composed of ions bonded together through ionic bonds. They do not contain carbon-hydrogen (C-H) bonds and are classified as inorganic molecules. Examples include sodium chloride (NaCl) and calcium carbonate (CaCO₃).

j. protein: Proteins are organic macromolecules composed of amino acids linked together by peptide bonds. They contain carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sometimes sulfur (S). Proteins play crucial roles in various biological processes.

k. O₂ gas: Oxygen gas (O₂) is an inorganic molecule consisting of two oxygen atoms bonded together. It does not contain carbon and is classified as inorganic.

l. DNA: DNA (deoxyribonucleic acid) is an organic molecule that contains the genetic instructions for the development and functioning of living organisms. It consists of nucleotides, which are composed of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and phosphorus (P). DNA is a fundamental molecule in genetics and heredity.

The density of titanium is 4.51g/cm^3. What is the volume (in
cubic inches) of 3.5lb of Titanium? this could be helpful D=M/V

Answers

The volume of 3.5 lb of titanium is 21.47 in³.

The density of titanium is 4.51 g/cm³.The weight of titanium is 3.5 lb.

Formula used:

Density, D = M/V, where D is density, M is mass, and V is volume.

The conversion factor of 1 inch³ = 16.39 cm³.1 lb = 453.592 g.

First, we will calculate the mass of titanium.

3.5 lb = 3.5 × 453.592 g

= 1587.772 g

Next, we will calculate the volume of titanium.

Volume of titanium = Mass of titanium / Density of titanium

= 1587.772 g / 4.51 g/cm³

= 352.044 cm³

Next, we will convert the volume from cm³ to in³.

1 inch³ = 16.39 cm³.

Volume of titanium in in³ = Volume of titanium / 16.39

= 352.044 cm³ / 16.39

= 21.47 in³

A compound consisting of carbon and hydrogen consists of 67.90%
carbon by mass. If the compound is measure to have a mass of 37.897
Mg, how many grams of hydrogen are present in the compound?

Answers

Given that the compound consists of 67.90% carbon by mass and has a total mass of 37.897 Mg, we can calculate the mass of hydrogen in the compound.

Let's assume the mass percentage of hydrogen in the compound is denoted by "y." According to the law of constant composition, the sum of the mass percentages of carbon and hydrogen is equal to 100.

Mass% of Carbon + Mass% of Hydrogen = 100

Since the mass percentage of carbon is 67.90%, we can calculate the mass percentage of hydrogen as follows:

Mass% of Hydrogen = 100 - 67.9

Mass% of Hydrogen = 32.1

Therefore, the compound contains 32.1% of hydrogen by mass.

Next, we can calculate the mass of hydrogen present in the compound using the following formula:

Mass of hydrogen = Percentage of hydrogen x Total mass of the compound / 100

Substituting the given values, we find:

Mass of hydrogen = 32.1 x 37.897 Mg / 100

Now, we need to convert the mass from megagrams (Mg) to grams:

Mass of hydrogen = 32.1 x 37.897 Mg x 10^6 g / 100

Calculating this expression, we find:

Mass of hydrogen = 12.159 grams

There are 12.159 grams of hydrogen present in the compound.
