Mole Snacks: +1815/-412 Gender: I am known to be occasionally wrong. Re: What exactly is inorganic chemistry? «Reply #2 on:February 28, 2022, 05:02:06 PM » I can be skewed here, but my feeling is that analytical is a more universal choice. No matter what you will work with...
A mole ratio is the ratio between the amounts inmolesof any twocompoundsinvolved in achemical reaction. Mole ratios are usedas conversion factorsbetween products andreactants in many chemistry problems. The mole ratio may be determined by examining the coefficients in front of formulas in a ...
Stoichiometry in chemistry pertains to the study of the relationship between the reactants and products involved in a chemical reaction. It is used in determining the limiting and excess reactants to predic the theoretical yield. Answer and Explanation: ...
The precipitate looks almost exactly like mine. thing is... it doesnt stay there if the electrolysis is continued. a dark liquid eventually takes over.. jsut like in your experiment. I have realized that there are so many reactions taking place that this isnt accomplishing my main reason of...
Suppose you had to build yourself a world exactly like the one we live in. Where would you start? You'd need people... cars... houses... animals... trees... and billions of other things. But if you had a few dozen different types of atom, you could build all these things and ...
Titration is a quantitative analytical technique used to determine the unknown concentration of an analyte of interest (the substance to be analyzed). It is performed by gradually adding an exactly known quantity of a substance (the tritrant), which reacts with our analyte in a definite proportio...
“The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12.” (14th CGPM, 1971) This present definition of the mole implies a fixed carbon-12 molar mass M(12C) equal to 12 g/mol exactly and involves ...
Specific Heat Capacity:The total amount of heat (in calories) needed to raise the temperature of one gram of water by one degree Celsius. What is Heat Capacity? Heat Capacity, Cp, is the quantity of heat required to change the heat content of 1 mole of material by exactly 1 degree Celsi...
