Draw the structure of methyl red, and explain why it absorbs in the visible region of the spectrum. using resonance, explain why the acid form has a wavelength of max absorption at longer wavelength than the base form (show resonance structures). Full explanation for 5 stars
Twenty grams of liquid mercury at 98.0 °C is placed in 47.0 g of water initially at 25.0 °C. What is the final temperature of the water, assuming the styrofoam calorimeter absorbs no heat at all?
consider the following reaction. Mg+H3PO4 magnesium phosphate and hydrogen. what is the molecular formula for magnesium phosphate.
how much energy in kilojoules is required to change 47.6 g of ice at 0 degrees celcius to liquid water at the same temperature in kilocalories?
Calculate the mass, in grams for a gold sample that absorbs 225 J to change its temperature from 15 Celsius to 47 degrees celsius.
25.0 mL of ethanol (density = 0.789 g/mL) initially at 5.4°C is mixed with 34.6 mL of water (density = 1.0 g/mL) initially at 25.3°C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?
Calculate the empirical formula for a chemical compound which gives the following analysis: 12.6 percent lithium, 29.2 percent sulfur, and 58.2 percent oxygen.
While shutdown, the core accidentally went critical and the reactor pressure vessel rose in temperature and was hot for two hours, but all instrumentation has failed and no one is sure what the temperature was.
what should the stock concentration of atp be so that if you pipette a 100 uL aliquot you will obtain a final concentration of 2mM in an assay volume of 3.0 mL
If 138 mL of wet H2 is collected over water at 24°C and a barometric pressure of 748 torr, how many grams of Zn have been consumed? (The vapor pressure of water is 22.38 torr at 24°C.)
If 1.50 g of X reacts with 3.54 g of M to produce 4.22 g of a compound with the formula M4X3, and the atomic mass of M is 48.5 amu.
What is the heat change in J associated with 74 g of gaseous butane at 91 oC changing to solid at -170 oC? c(butane) (gas) = 2.31 J/ (g.K) c(butane) (liq) = 1.65 J/(g.K) c(butane) (s) = 1.32 J/ (g.K) ?Hfus(butane) = 6.885 kJ/mol
