What is the temperature of a gas if 5.0 moles of the gas occupy a 10 liter container at a pressure of 2.5 atm? Calculate the molar concentration of each ion (Na+ and PO4 3-) in a aqueous Na3PO4 solution when 2.0 g of Na3PO4 is dissolved in water so that the final volume of the solution is 150 ml.
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
what are the chemical shift,integration(#H),multiplicity,assignment and type of hydrogen in C8 H10 O and i have to identify the unknown. help please i have 4 signals
which of the following alkyl halides reacts most rapidly via SN1 solvolysis reaction in hot methanol? A) 1-iodo-1-methylcyclohexane
Comment on whether these are made of the same materials or not, and explain your response. The density is different in each, so they are made of different materials.
A 5% solution by weight of an unknown non-electrolyte in water has a density of 1.018 g/mL if this solution exhibits an osmotic pressure of 3.57 ATM at 25C what is the MM of the unknown
Calculate w (in kJ) when 422 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 445 K:
Since the periodic table currently has 7 periods (and will have 7 until element 119, which will be the first element of the 8th period, is "discovered"), consider the electron shell with principle quantum number, n = 7.
Draw the product for the chlorination of 2-methylbutane that proceeded through a secondary radical.
Then the gas is cooled at a constant volume of 25.0L back to its original temperature. Then it contracts back at a constant tempurature to its original volume. Find the total heat flow for the entire process.
Nickel nitrate and potassium carbonate react to form nickel carbonate and potassium nitrate. How many milliliters of 0.55M Ni(NO3)¬2 are needed to react with 85 mL of 0.25M K2CO3?
The activation energy of an uncatalyzed reaction is 91kJ/mol . The addition of a catalyst lowers the activation energy to 61 kJ/mol .Assuming that the collision factor remains the same, by what factor will the catalyst increase the rate of the rea..
Calculate the standard potential for this reaction. Normally, X is Fe. Here it is some unknown metal, allowing for somewhat random values for ΔGo.
