Then measures the battery voltage at the outlet to match the Nernst voltage. It can thus determine the utilization factor on the basis of the table. This method can be used to determine the flow distribution and flow rate in the electrochemical cell stack.クラーイ ヘラルト ヤン...
In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
The stoichiometry of reaction helps to determine the actual amount of product formed from reactants. We need a balanced chemical reaction to get the exact ratio of reactants and products in terms of moles.Answer and Explanation: Given bala...
Chemical reactions refer to the processes of converting reactants into required products. The mass of products formed can be determined from the moles and mole ratios between the products and reactants.Answer and Explanation: Given data : Mass of potassium ...
the enzyme that aids in the digestion of milk sugar that millions of people's bodies fail to produce), it is not surprising that biologists have come up with formal tools to assess how well specific enzymes do their jobs under given, known conditions – that is, determine their catalytic ef...
How many reactants are in a synthesis reaction? Are all chemical reactions redox? How is the rate of a chemical reaction expressed? What must happen for a chemical reaction to occur? How can a balanced chemical equation be used to determine the volume of a gas that will be produced from...
This example problem demonstrates how to examine the reactants and products to predict the sign of the change in entropy of a reaction.
Chemistry students routinely use skeleton equations in order to balance the equations for chemical reactions. The reactants of the equation are typically on the left-hand side of the equation and the products are on the right-hand side, which gives the e
This is in contrast to a physical change where the substance(s) do become different but are made of the same material with the same properties. In a chemical change, the atoms of the reactants break apart and rearrange themselves into new arrangements or molecules. This makes a new ...
