Question #1aa66 + Example - Socratic The sentence "Van has come " is grammatically correct IF the noun "Van" is the name of a person A proper noun is not usually preceded by an article If the noun "van' is a common noun, a word for a type of vehicle, the noun should be preceded by the article "the" when the "van" is one that is expected, or preceded by the article "a" when the "van" is not one that is expected; for example
Question #9f38f - Socratic L=1 01m Parameters L = ? g = 10ms^-2 pi = 22 7 T = 2sec From S H M T = 2pisqrt (L g) Making L the subject of formula T = 2pisqrt (L g) Divide both sides by color
How does chlorate oxidize hydrazine to give NO and . . . - Socratic 3N_2H_4(g) + 4ClO_3^(-)(aq) rarr 6NO(g) + 6H_2O(l) + 4Cl^(-)(aq) This is one equation for the oxidation of hydrazine to nitrous oxide It also accords with your question Quite clearly, the equation should have appeared with the question
Question #f4ea2 + Example - Socratic Friction and other factors will always prevent this To be 100% efficient, all input energy would need to be converted in to useful output energy In any real engine, there will always be friction (since there will always be moving parts) so the engine can never be 100% efficient as energy will be used to overcome the friction (work will be done) Other energy losses may also occur (e g Heat
Question #74006 - Socratic (d) is the correct option CH_3CH(OH)CH_2CH_2CH_3 (pentan-2-ol) being secondary alcohol on oxidation first tansformed into ketone CH_3CH(OH)CH_2CH_2CH_3stackrel([O])-> CH_3COCH_2CH_2CH_3 Further oxidation of ketone is difficult but can be performed in extreme conditions and oxidation product is obtained following Popoff's rule Popoff's rule states that during oxidation of unsymmetrical
Suppose you ran this sequence of reaction starting with 8. 0 g of . . . Suppose you ran this sequence of reaction starting with 8 0 g of benzoic acid, excess methanol, and excess phenyl magnesium bromide What would be the expected theoretical yield of triphylmethanol?? Show all calculation Chemistry

Question #0e55c - Socratic Find the real roots of 256 2401 then consider the imaginary values that correspond to each of the real roots First we consider only the two real roots, which we can find but taking the 4th root of 256 2401: root (4) (256 2401)=+-4 7 Now consider that i^4=1, where i is the imaginary unit sqrt (-1): We can apply an i to each of the real answers to get: +-4 7i without changing the answer when we
