Using the ideal gas equation:

pV = nRT
n = pV / RT

1atm = 101325Pa, so p = 10132500Pa
1L = 0.001m^3, so V = 0.050m^3
R = 8.214 (ideal gas constant)
T = 273K

Hence moles of CO2 = (10132500 * 0.050) / (8.314 * 273) = 223.2101553

Reaction ratio between oxygen and CO2 is 1:2
Hence moles of O2 = 223... / 2 = 112 moles (3sf)

3) Classify the following statements as either a theory (T), a fact (F), a law (L), a
mrs_skeptik [129]

Answer:

Explanation:

Before answering the questions, it is important to define these given terms:

  1. Theory: a theory can best be simply defined as an explanation of a phenomenon usually drawn from careful observation.
  2. Fact: fact is a proven information that has been known to exist or occur.
  3. Law: scientific laws are usually mathematical expressions that seeks to explain a certain observation with some exceptions.
  4. Belief: it is an ideology based on wether a thing exists or not.
  5. Hypothesis: It is simply a scientific guess or an untested idea.

a) There are 2 countries in North America: Belief

The idea that there are just two countries in North America is wrong. A person might choose to hold on to this false knowledge despite strong evidence that can annul this system of reasoning. He or she might be coming from the point view that in terms of economic prowess, there are just two countries in North America. This is more of a belief.

b) If I jump out a window I will die: belief.

This is more of a belief, there is nothing to prove that if one jumps out of a window, death is inevitable.

c) Through the process of natural selection humans, chimpanzees and

gorillas evolved from a common ancestor species.: Theory

This is a theory that seeks to provide a scientific basis to evolution. To come to this conclusion, observations have been made on humans, chimpanzees and gorillas.

d) Energy can be converted into matter in ratio of E=mc² : Law

This is a scientific law which has been simplified in form of mathematical expression to show the relationship between mass energy.

e) Canada is the greatest country on earth: Belief

This is a mere belief. Almost every Canadian can attest to this assertion. It is a thing of national pride and loyal for one to belief their country is the greatest.

f) Illness comes from microscopic germs, some of which, bacteria can be

seen under the microscope and cultivated outside a host, and others,

viruses, are too small to see under the microscope: Fact

It is a proven fact that germs causes diseases.

What is an example of kinetic energy at work,1 a ball lodge in the tree, 1 a frisbee flaying in the air, 3 a car in the garage
AfilCa [17]

Answer:

a frisbee flaying in the air

Explanation:

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where;

  • K.E represents kinetic energy measured in Joules.
  • M represents mass measured in kilograms.
  • V represents velocity measured in metres per seconds square.

Hence, an example of kinetic energy at work is a frisbee flaying in the air because it would possess energy due to its motion in the air.
