Answer:
363.64g of oxygen would be required.
Explanation:
1) Write and balance the combustion equation for propane.
Propane + Oxygen --> carbon dioxide + water
C3H8 + O2 --> CO2 + H2O
Upon balancing, we have;
C3H8 + 5O2 --> 3CO2 + 4H2O
2) How many grams of oxygen are required to burn 200 grams of propane.
From the reaction;
Propane = (3 * 12) + (8 * 1) = 44
Oxygen = (5 * 16) = 80
80 grams of oxygen is required to combust 44g of propane.
80 = 44
x = 200
x = ( 80 * 200 ) / 44
x = 363.64g
Steps of a scientific investigation include identifying a research question or problem, forming a hypothesis, gathering evidence, analyzing evidence, deciding whether the evidence supports the hypothesis, drawing conclusions, and communicating the results.
Answer:
Kinetic theory of gases is a description of gas as a large number of non-stop random moving particles (atoms or molecules, generally without distinction in physics, are called molecules). Fast-moving molecules continuously collide with other molecules or the walls of the container. Molecular motion theory is to explain the macroscopic properties of gas, such as pressure, temperature, volume, etc., through the composition and motion of molecules. The theory of molecular motion believes that pressure does not come from static repulsion between molecules, as Newton’s conjecture, but from collisions between molecules that move thermally at different speeds.
The molecule is too small to be seen directly. The random movement of pollen particles or dust particles under the microscope-Brownian motion, is a direct result of molecular collisions. This can be used as evidence of the existence of the molecule.
Temperature is a measure of the average kinetic energy of the particles in a substance. Temperature of a volume of air represents the average kinetic energy of its molecules. Temperature is a measure of the average kinetic energy of a substance.
According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature. where T is the Kelvin temperature and k is Boltzmann's constant.
Gas because it's water vapor
