(v)Draw a fully labelled diagram of the apparatus you would use to determine the standard electrode potential of the dichromate(VI)/chromium(IIl) electrode at 298 K, using a standard hydrogen electrode.(5)(d) The mass of ethanol in 5.00 cm3 of white wine is found by oxidising the ...
Molar Mass of H2O:18.02 g/mol ElementSymbolAtomsMass % HydrogenH211.2% OxygenO188.8% Relate the moles of standard solution to the moles of unknown solution. Because this is a neutralization reaction, assume that the standard solution is the base (OH- ions). You calculated the moles of base...
The molar mass of an element can be directly obtained from a periodic table. It is typically given in units of g/mol. For compounds however, where two or more elements are chemically combined together, it is necessary to compute the molar mass by adding up the atomic masses of each of ...
Here are the most common factors that affect water needs. Activity Level and exercise: People who exercise or do rigorous activity will need to consume more water daily. However, the exact amount varies depending on the activity, muscle mass, and climate. Climate and temperature: If you live...
The reaction is now Mg(OH)2 + 2HCl –> MgCl2 + 2H2O. 2. Find Molecular Weight Convert reactant quantities to moles. Use a periodic table to find the atomic mass units for each element. For example, say you have a solution of 65 grams of magnesium hydroxide and 57 grams of ...
