How do you account for the difference in reaction between the fresh and rancid oil?
Oxygen.Oil is a hydrocarbon,rancid oil is oxidized, thus its a kind of carbohydrate. (not the good kind).
What is the importance of reaction rate?
As the reaction proceeds the concentrations of the reagents are not known. However, at the start of the reaction the initial concentration of the reagents IS known. Any orders that are calculated from average rates may not take into account such factors as autocatalysis or any mechanistic change due to concentration effects. Initial rates allow more reliable information to be determined regarding orders, activation energies and possible mechanisms (which is the ultimate aim of reaction kinetics)
What is the function of a chemical equation?
To let you know what kind of atoms (and how many) make up certain molecules. For example H2O is a chemical equation for a molecule of water. It shows us that there are 2 atoms of Hydrogen and 1 atom of Oxygen in a water molecule. Hope this help! -Sixth Grade Science Teacher
Distinguish between ideal and real stoichiometric calculations?
The theoretical yield of a reaction is the amount of some product, usually given in mass units of grams, that you would expect to get if the reaction based on a stoichiometric calculation not actually "running" the reaction in the laboratory. The actual yield is just that,it is the actual amount of product, in grams you actually produced after really running the experiment in the lab.Actual yield data comes from experimentally determined results. You can not "calculate" it.
What is the cement hydration?
Hydration process is a chemical reaction takes place between cement and water.Heat of evolution takes place.C3A > C3S > C4AF > C2SC3S + H2O ------> Ca(OH)2On account of hydration certain products are formed which have adhesive and cementing value.
What are the use of a calorimeter?
A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calore, meaning heat. Differential scanning calorimeters, isothermal microcalorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber.
What error would be introduced into the value of J on failing to take into account the heat absorbed by the stirrer?
' J ' means Joules , unit for the amount of Energy in Physical Science... Heating Effect of Current ... Joule's Constant = Electrical Energy in Joules / Amount of Heat in calories Electrical Energy in Joules = Voltage in volts x Current in amperes x Time in seconds Amount of Heat in calories = Mass of Water x Specific Heat of Water x Change in Temperature of Water + Mass of Calorimeter x Specific Heat of Calorimeter x Change in Temperature of Calorimeter ANSWER: The Amount of Heat will be very hot and Joule's Constant will be too big which will make it not realistic as part of the experimental calculations. You must know that it is necessary to get the temperature in the state of equilibrium. Remember that, due to the use of the metal stirrer which absorbed the heat energy, the temperature of water inside the calorimeter had decreased partially or was delayed in rising up despite to the fact that the electrical energy generated is proportionally equal to the increase in temperature of the calorimeter.
What is provision for depreciation?
Provision of depreciation account is the account of provision of depreciation.First of all we should understand provision of depreciation .Provision of depreciation is the collected value of all depreciation. With making of this account we are not credited depreciation in asset account. But transfer every year depreciation to provision of depreciation account. Every year we adopt this procedure and when assets are sold we will transfer sold assets 'total depreciation to credit side of asset account. For calculating correct profit or loss on fixed asset. This provision uses with any method of calculating depreciation.
How does the amount of reactants account for the differences in the rate of reaction?
The more reactant, the faster the reaction The less reactant, the slower the reaction hope that clears it up for you
What error would be introduced into the value of J in failing to take into account the heat absorbed by the stirrer?

How do you choose a pump for your rural house water supply?
By calculating the fixture requirements and taking friction losses into account and then you choose the pump from this
How do you account for their differences in the rate of reaction of these metals?
It is a limitation of the second law of thermodynamics that it is not able to give the rate of a chemical reaction.
Is your agility level taken into account for calculating your run energy recharge time on a free world?
No, this effect would not apply on a Free-to-Play World.
