I initially had a really hard time on our conversion factor unit, so I really need help on how to solve this problem: The diameter of the tungsten wire in a light bulb filament is very small, less than two-thousandths of an inch, or about 1/20 mm. The mass of the filament is also very small, 0.0176 grams. How many tungsten atoms are in a typical light bulb filament?

Water's surface tension and heat storage capacity are accounted for by its a) orbitals b) weight c) hydrogen bonds d) mass e) size

Draw the aromatic compound toluene (methylbenzene). show all hydrogen atoms, including those on the ring.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
