I was introduced to nichiren buddhism in 1992. The most important practice of nichiren Buddhism (in my opinion) is the chanting of nam-myoho-renge-kyo. everything else (again, in my opinion) is not important. I knew that the chanting of nam-myoho-renge-kyo is the act to submitting to...

can the second law of thermodynamics be defied? in other words, can mother nature be fooled somehow? have we (homo sapiens) accomplished such a thing with religion? for example, the seventh day of the week is nothing but a positive entropy change from sunset to sunset. can we somehow use that...

to make a profit means to sell goods at a price higher than what i pay to produce the goods. the provider of the means (capital) to produce the goods sells the capital at a price higher than what the provider pays to provide the capital. why?

i don't understand. can you give me an example? let system A = a liter of gas. let system B = a liter of another gas. let me rephrase what you said. temperature is a calibrated yardstick for comparing the kinetic energy between A and B. length, mass, time are combined with a constant of...

i've been reading resnick, halliday, and krane physics, volume one, fourth edition on temperature. let system A = a liter of gas containing 3 * 10^22 molecules. let E = the environment of A the temperature (a macroscopic quantity) of A is related to the average kinetic energy of...

Mg (s) + HC2H3O2 (aq) --> Mg(C2H3O2)2 (aq) + H2 (g) i balance the equation: Mg (s) + 2HC2H3O2 (aq) --> Mg(C2H3O2)2 (aq) + H2 (g) then i write the equation, listing all the species present in solution. Mg (s) + 2H(+) (aq) + (C2H3O2)2(2-) (aq) --> Mg(2+) (aq) + (C2H3O2)2(2-) (aq) +...

i see now. thanks! francisco

1.0 g * (1 mol / X g) = 0.011 mol. yes, i think i follow. 1 mol * (1.0 g / 0.011 mol) = 90.9 g. is it wrong to use the empirical formula to find the molecular mass? i would use the molecular formula to find the molecular mass, but the molecular formula is what is in question. what...

molecular weight = 1.00794 g H + 3*(12.0107 g C) + 5*(1.00794 g H) + 3*(15.9994 g O) = 90.8 g HC3H5O3. 17.0 mL*(L/1000 mL)*(0.65 mol NaOH/L) = 0.011 mol NaOH. since to reach the end point titration means to reach the point at which the number of moles of NaOH is equal to the number of...

i also need help with the following problem: lactic acid (found in sour milk) has an empirical formula HC3H5O3. a 1.0-g sample of lactic acid requires 17.0 mL of 0.65 M NaOH (sodium hydroxide) to reach the end point titration. what is the molecular formula of lactic acid? thanks...

i need help with the following problem: rewrite the following unbalanced equation, changing it to a balanced net ionic equation. Mg (s) + HC2H3O2 (aq) --> Mg(C2H3O2)2 (aq) + H2 (g) thanks. francisco

i am a disabled american veteran. my disability is schizoaffective disorder. i was born with this disability or mental illness. serving in the army during the vietnam war aggravated it. generally there are two types of psychosis. one is schizophrenia, and the other is manic-depression...

the function fails to exist at 4 (c = 4). why? what happens to the graph, in other words, what are the values of f(x), as x gets closer and closer to (approaches) 4 from the left? for example, what are the values of f(x) when the values of x are 3.5, 3.8, 3.9, 3.95, 3.99, 3.995, 3.999,...and so...

physics, abstract... i am very confused about what the following abstract says: The main purposes of this paper are (i) to illustrate explicitly by a number of examples the gauge functions chi(x, t) whose spatial and temporal derivatives transform one set of electromagnetic potentials into...

the speed of light in a vacuum... the speed of light in a vacuum is a true constant of nature, independent of the wavelength of the light or the choice of an (inertial) reference frame. is there any sense, then, in which einstein's second postulate can be viewed as contained within the scope of...
