Answer: n=15.56moles
Explanation:
PV = nRT
where
P is pressure in atmospheres
V is volume in Liters
n is the number of moles of the gas
R is the ideal gas constant = given as (0.0821L -atm/k-mol
PV = nRT
n= PV/RT
n= (1.5 X 230)/ (0.0821 X 270)
n= 15.56 moles
The kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.
<h3>What is an
amino acid?</h3>
An amino acid refers to a simple and organic chemical compound that consist of an acidic carboxyl group (COOH), a basic amino group (
), and a unique side chain group.
<h3>What is a protein?</h3>
A protein can be defined as a <u>hydrophilic</u>, macromolecule (polymer) that is formed as a result of the union of many amino acids.
Generally, a protein contains the following chemical elements:
In conclusion, the kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂) is 12 grams
The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.
It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.
C(12g) + O(16g) ⇒ CO (Carbon Monoxide)
C(12g) + 2O(32g) ⇒ CO₂ (Carbon Dioxide)

Answer: Option (c) is the correct answer.
Explanation:
Wood is a mixture of different substances. Primarily it consists of cellulose, lignin, water etc.
When we heat wood then all these substance oxidize into the atmosphere even before they could melt.
Whereas iron, sodium chloride and ethanol all are the substances which can melt at any temperature.
Thus, we can conclude that out of the given options, wood, a mixture of different substances is a material that does not melt at any temperature.
Answer is: <span>A. spontaneous reactions release.

ATP
is short for adenosine triphosphate<span>
Adenosine triphosphate converts to either
the adenosine diphosphate (ADP) or adenosine monophosphate
(AMP), in this process energy is released (for example </span> glycolysis, the citric acid cycle or oxidative phosphorylation and beta-oxidation).
ATP is made of three components: the
triphosphate, the sugar ribose and a nitrogenous base (adenine).
