Molar

the molar flow rate by dividing by the molar mass of 0.058 kg/mole to obtain 29.9 mol/s. Use the selectivity table to calculate the amount of DE and PY formed according to the three reactions taking place. Use the molar ratios of the three simultaneous reactions to calculate the molar and mass composition of IP and WA in stream 1. Use mass balancing to calculate the molar and mass composition of IP, AC, DE, PY, HY and WA in stream 2. Use the ratio of the molar flow rates to calculate he molar…

was calibrated with the blank sample, a 0.4 Molar solution of copper (II) sulfate was then placed in the cuvette. Once the 0.4 molar solution was added, we determine the appropriate wavelength by identifying the highest peak from the graphs generated. After carefully examining the graph, we decided that the appropriate wavelength to use for studying copper (II) sulfate was 631.1…

flattened upper lip. Incisors - Chiselled shaped teeth are located in the front and mid-section of the mouth. Canines – sharp pointed teeth located both sides of the mouth (top and bottom). Premolars - The teeth have cusps and are in front of the molars. Molars – Blunt cusps located at the back of the mouth. Thick mass of skeletal muscle covered in mucous membrane. Physiology Allows mechanical and chemical digestion to occur. It predominantly…

Imagine the best desert gets served right in front of your face but you aren't able to eat it because you don't take care of your teeth and the food is too rough for your teeth. That is the.worst possible situation, so that's why you should take care of your teeth to eat that breathtaking dessert because teeth are a very important part of your body. Usually when you hear teeth you think, losing teeth, why, how do we lose them. Most of the time children start to lose teeth at 6 or 7 because…

used with these two enthalpies and the enthalpy of formation for water to find the enthalpy of combustion for the target equation, Mg(s) + ½ O2(g) → MgO(s). The two reactions performed in this lab will be exothermic reactions which means that the molar enthalpy of combustion of magnesium will also be exothermic with a very low number because a lot of heat and light is…

the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that is going to be discussed is a brief background of stoichiometry and terms to remember. Based from the definition, we can derive the two parts of stoichiometry, the composition and the reaction. Section I. Molar Mass is the sum of the masses of the…

HEMISECTION: A CASE REPORT ABSTRACT The loss of posterior molar can result is several undesirable sequelae including shifting of teeth, collapse of the vertical dimension of occlusion, super eruption of opposing teeth, loss of supporting alveolar bone and a decrease in chewing ability. The treatment options to replace severely damaged and possibly unrestorable teeth include removable partial denture, fixed partial denture and dental implants. A guiding principle should be to try and maintain…

The purpose of this experiment is to demonstrate the molar mass by using the freezing points of the two solutions. Colligative properties were used in calculations during this experiment to discover the molar mass of an unknown solute. These properties are subsequently applied to solutions depending on the amount of particles of the solute and the solvent inside the solution. In this lab, we focus on the freezing point depression, which can be seen when a pure solvent is added to or mixed with a…

Formal Lab Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas…

The atomic radius will slowly decrease as you move across a period on the periodic table; this is caused by the addition of protons found in the nuclei of the elements. For every new proton being added, several electrons will also be included into this process by joining the identical energy level (ultimately accounting for one electron per element in said period). The electrons then attract the protons, whilst failing to shield from or repulse this attraction. Given the above information, the…
