LAB REPORT ON VERIFICATION OF HESS’S LAW Our purpose of doing this lab was to prove the Hess’s law correct. Hess’s law suggests that the enthalpy change of a reaction must be equal to the sum of the enthalpy changes of the related reactions which lead to the original reactions. The following are the reactions at the lab; 1) NaOH ( s) NaOH (aq) 2) NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) 3) NaOH (s) + HCl (aq) NaCl (aq) + H2O (l) As explained before‚ Hess’s Law states that the enthalpy

use of a trolley‚ ticker-timer and set of slotted masses. Introduction: Newton ’s second law states "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force‚ in the same direction as the net force‚ and inversely proportional to the mass of the object.." Unlike Newton ’s first law‚ the second law deals with objects and forces that are not balanced. The law simply states that the acceleration of an object depends on the net force acting upon

Newton’s Laws First let’s get to know some history about the man behind all of this‚ Sir Isaac Newton. Sir Isaac Newton‚ the man who is responsible for what we all have come to know as the “Laws of Motion” was born on January 4‚ 1643‚ which is very often displayed as December 25‚ 1642‚ if using the older version of the Julien calendar‚ in the Helmet of Woolsthorpe‚ England. Sir Isaac Newton is believed to be one of the most influential scientists known to have ever lived. His ideas became the basis

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

How Newton’s 3rd Law Applies to Bottle Rockets Newtons 3rd law of motion: For every action‚ there is an equal and opposite reaction. How this applies to our bottle rockets that we constructed‚ is that when we release‚ the water and air pressure comes out of the bottom. That pushes against the ground‚ the equal and opposite reaction is the earth pushing back up. Whatever object has less mass moves. In this case‚ the rocket has less mass than what it is pushing against; the earth. When we

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
