How do you simplify # (3+2i) (3-2i)#? - Socratic This is a useful 'tool' in complex numbers] If a + bi is a complex number then a - bi is called the 'conjugate' and the product (a + bi) (a - bi) is always real
Question #f1060 - Socratic The complete equation is Bi2O3(s) + 3C (s) → 2Bi (s) + 3CO(g) That satisfies two of the requirements This is a single replacement reaction, because C is replacing the Bi in Bi2O3 And that satisfies the third requirement
How do you prove #\sec ( - \theta ) + \cot ( \frac { \pi } { 2 . . . If y is imaginary, the process is termed complex conjugation: the complex conjugate of a + bi is a − bi, where a and b are real Tip - Solving or proving trigonometric identities is a lot more similar to algebraic identities than you think! Pra ticing simple algebra can do wonders for your trigonometric skills!
How do I test for the contamination of water with iodide ions? P b2+ +2I − → P bI 2(s) ⏐↓ Lead iodide is very insoluble, and precipitates from aqueous solution as a canary yellow solid So treat the water from the pipe with P b(N O3)2(aq) to see if precipitation occurs I propose that you test the reaction by mixing P b(N O3)2(aq) with N aI (aq) so that the results of a positive test can be appreciated And now test the water from the pipes with
Question #384ab - Socratic I think only ΔG‡ The rate of a generic bimolecular reaction can be expressed as rate=k*e^(-(ΔG‡) (RT) ΔG‡ is the activation energy and its value effects both the forward and reverse reactions The other three notations are different variations of Gibbs Free energy DeltaG generally looks at the spontaneity of a reaction in the direction it is written (or reverse) not bi-directional
