Which balance is more accurate triple beam or electronic?
A triple-beam balance is the best all-around mechanical balance with good sensitivity and high capacity. A digital scale is much faster and easier to use than a mechanical balance for weighing out small amounts of chemicals for chemistry. A 200 g digital balance with 0.01 gram accuracy will work for most labs.
What is a mass balance diagram?
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
What is the law of mass balance?
law of mass balance. if the amount of a substance in the body is to remain constant, any gain must be offset by an equal loss.
Why are mass balances important?
In industry, mass balances are widely employed in engineering, and environmental analyses ( 1, 2 ). For example, mass balance theory is used to design chemical reactors, to analyze alternative processes to produce chemicals, as well as to model pollution dispersion and other processes, just to name a few.
What is active mass?
1 : the concentration of a reacting substance expressed usually in moles per liter. 2 : the concentration of the portion of a dissolved electrolyte that is dissociated into ions and hence is capable of carrying the electric current.
What is law of mass action state with an example?
Law of mass action, law stating that the rate of any chemical reaction is proportional to the product of the masses of the reacting substances, with each mass raised to a power equal to the coefficient that occurs in the chemical equation.
What is active mass give formula?
Active Mass = w /mV(l) Calculate the active mass or molar concentration ? Ans. w of H2 =4 gm.
What is K in law of mass action?
A system not at equilibrium tends to become at equilibrium, and the changes will cause changes in Q so that its value approaches the equilibrium constant, K: Q→Keq. The mass action law gives us a general method to write the expression for the equilibrium constant of any reaction.
