the specific heat of an unknown metal is found to be 0.233 j kg. The law of dulong and petit predicts a molar heat capacity of J/K mol. Use this law to estimate the molar mass of the element.
Calculate the percent manganese in the sample as Mn3O4 (only part or none of the manganese may exist in this form, but we can make the calculations on the assumption that it does)
suppose 45.0g of water at 85 C is added to 105.0 g of ice at 0 C. The molar heat of fusion of water is 6.01 kJ/mol, and teh specific heat if water is 4.18 J/g C. on this basis of these data (a) what will be the final temperature of the mixture and..
50.0 mL of 1.0 M HCl at 25.0 oC were mixed with 50.0 mL of 1.0 M NaOH also at 25.0 oC in a styrofoam cup calorimeter. After the mixing process, the thermometer reading was at 31.9 oC.
Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling point constant is 5.03°C · kg/mol, and the boiling point of pure carbon tetrachloride is 76.50°C.
Which reaction sequence would be best to prepare m-chloroaniline from benzene? a. chlorination, nitration, reduction
Carbonyl bromide decomposes to carbon monoxide and bromine. COBr2 (g) ↔ CO(g) + Br2 (g) Kc is 0.190 at 73?C. If you place 0.500 mol of COBr2 in a 2.00 L flask and heat it to 73 ?C,
Consider the following equation: 2Mg(s) + O2 (g) → 2MgO(s). How many grams of MgO are produced when 40.0 grams of O2 react completely with Mg?
A beaker with 145mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M
Chemistry Questions on Calculate P H
Solids do not "flow". What does this behavior imply about the speeds at which the individual solid particles are moving relative to each other?
An auto bumper is coated with a layer of chromium, 0.017 cm thick. The bumper has a surface area of 3.43 x 104 cm2. The density of chromium metal is 7.19 g/cm3. How many atoms of chromium are used in the coating?
