Comparing the intensity levels of two different sounds of intensities I_1 and I_2, IL_2 - IL_1 = (10 dB) [\log_ {10} (I_2/I_0) - \log_ {10} (I_1/I_0)] But, \qquad \log_ {10} (a) - \log_ {10} (b) = \log_ …

The pendulum reaches a displacement of 10mm in 0.0314 s after crossing the equilibrium point. The frequency is 5 Hz and the amplitude is 0.012 m. One function that could result in the …

An organic compound was taken for combustion.14.77 g was burned in oxygen.The result of combustion gave 43.26g of CO2 &12.40g of H2O.Determine the empirical formula?

Jun 9, 2016 · It will pass all quadrants. It will intersect the negative y-axis and both the positive and the negative x-axis. Whatever value x has, |x| will never be negative. But f (x)=-6 if x=0 …

Sep 5, 2016 · The log is the exponent of the hydrogen ion concentration so the log is -1 but pH is the negative log so # -1 xx -1 # = 1 Example if the solutions is only 1% ( 1/100) or .01 # {H^+}# …

log (0.01^2/x^3) = -10.64 I assume that log means the logarithm with base 10. By the property log (a/b)=log (a)-log (b) we get: log (0.01^2) - log (x^3) = -10.64 log ...

Well, we know that 6.022xx10^23 beryllium atoms have a mass of 9.01*g... How do we know this....well 6.022xx10^23 specifies Avogadro's number, and the atomic masses are …

Dec 10, 2016 · A gas mixture contains 1.19 g N 2 and 0.79 g O2 in a 1.60-L container at 25 deg C. How do you calculate the mole fraction of N 2?

The thing to keep in mind here is that nitric acid is a strong acid, which means that it will ionize completely in aqueous solution to produce hydronium cations, H3O+, and nitrate anions, NO− …
