When considering taking supplements‚ how often do we consider taking magnesium supplements? This mineral helps on the process of over 300 functions in our body‚ most important neurotransmitter and heart functions‚ and its consumption is essential for the regulation and development of these activities. The brain is one of the organs that benefit the most in taking magnesium supplements‚ magnesium activates ATP‚ a coenzyme that regulates your energy levels‚ making it a good complement to treat fatigue

product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected

From the experimental data and through its analysis‚ the enthalpy of combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol

Vocabulary: • Conduction- the passage of energy‚ particularly heat or electricity‚ through something • Rate of Change- the ratio of the difference in values of a variable during a time period to the length of that time period • Calorimeter- an apparatus for measuring the amount of heat given out or taken in during a process such as combustion or change of state. The measurements are often made by observing the amount of solid liquefied‚ or liquid vaporized‚ under set conditions. • Conservation

fuel saving techniques employed by drivers. "You can do a lot as far as saving fuel is concerned by taking certain steps‚" said Devendra‚ an auto expert. He advised that air filter should should be cleaned regularly for better flow of air into the combustion chamber for igniting the fuel better. "This step can easily save fuel‚" he added. Similarly‚ owners should go for regular cleaning of fuel filter for a proficient compel. He‚ however‚ admitted that vehicle owners have now become more aware as far

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g
