Determinants of aggregate demand Questions and Videos - Socratic Questions What are the determinants of aggregate demand? What would cause the aggregate demand curve shift upward? What is the concept of aggregate demand? How did World War II help end the Great Depression?
Question #5ce05 - Socratic Now for the tricky part When chemists report an elemental analysis and it adds up to less than 100%, the difference is generally attributed to oxygen Our analytical methods, constrained by working in an oxygenated and water-laden world, do not in general detect or measure oxygen directly Instead we infer it by difference after accounting for the other elements
Question #c9e1c - Socratic OK, because the problem statement is ambiguous, I'd rather try to prove a more general and--presumably--more useful result I shall prove that, if a b is rational and x is irrational, then their sum a b + x is irrational (a and b are integers and b!=0) I'll use a proof by contradiction: let's assume that the sum of the two numbers is rational This means that the sum can be written as a ratio
Question #1bdf3 - Socratic The two roles of KMnO_4 are as an oxidising agent and as a provider of a catalyst I am assuming you are referring to the oxidation of ethandioate ions by "Mn(VII)" The half equations are: MnO_4^(-)+8H^++5erarrMn^(2+)+4H_2O C_2O_4^(2-)rarr2CO_2+2e You can see that to get the electrons to balance we need to X the top equation by 2 and the bottom equation by 5, then add This gives: 2MnO_4
Question #88e62 - Socratic The mass of hydrogen gas is "27 g" You are asked to determine the mass of a gas in a weather balloon filled with hydrogen, therefore, the gas is hydrogen gas, "H"_2 First you need to determine the moles of hydrogen gas at STP by using the ideal gas law Once you know moles, you will determine the mass by multiplying by the moles by the molar mass of "H"_2" ("2 016 g mol") Equation for the
