Joshua McMahon IB Chemistry Matt Chase 3A 11/5/14 Finding the Molar Enthalpy Change of sodium bicarbonate by using Hess Law Research Question By using Hess’ Law‚ can the Molar Enthalpy Change of sodium bicarbonate be calculated? Hypothesis If we are attempting to determine the enthalpy change of the thermal decomposition of Sodium Bicarbonate‚ then Hess’s Law will be will be the most effective. Introduction Sodium bicarbonate‚ more commonly known as baking soda‚ has many uses in todays

determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring‚ e‚ is denoted

Reflective Writing 6 In the textbook it states Newton’s third law as how two objects interact with each other. For example when you take a seat on a chair you are pushing down on the chair while the chair is pushing back up on you which is also known as the normal force. With this interaction between two objects there will be an action and reaction pair of forces. For example force A acts on B and force B acts on A. These exist as a pair or not at all. The name is also misleading because you cannot

Newton’s Three Laws of Motion Sir Isaac Newton first introduced his three laws in 1686. Newton’s Three Laws of Motion not only improved math and science all over the world‚ but they played a major role in the development of human beings giving us a better understanding of the world in which we live and the laws that each and every one of us follow. Newton’s first law is law of inertia‚ which is a restatement of Galileo’s idea‚ an object in rest stays in rest or an object in motion stays in motion

Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

against slavery due to the serious moral and ethical dilemma associated with the practice of slavery. Leading statesmen who oppose the old constitution in the United State of America‚ argued that the enslavement of the African was in violation of the laws of nature; and that is was wrong in principle‚ socially‚ morally and politically. The slave trade at the time was so profitable for the people that were involved in it’s practiced‚ the Abolitionist‚ were opposed by a pro-slavery West Indian lobby.

Prac Report Problem: How does the increase mass affect acceleration and the force of the accelerating object? Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled

According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature

Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges
