zinc hydroxide is insoluble in water but dissolves when nitric acid solution is added, why. Write balanced/ total net ionic equation
The rate constant (k) for a reaction was measured as a function of temperature. A plot of ln k versus 1/t (in K ) is linear and has a slope of ?1.13×10^4 K.
An unknown compound has the empirical formula CH2. A 0.050-mol sample of this compound weighs 4.20 g. What is the molecular formula of this compound?
calculate the mass, in grams, at 25 degrees celcius of 30.0mL of propylene glycol, which has a density of 1.036g/mL
A block of metal has a width of 3.2 rm cm, a length of 17.1 rm cm, and height of 4.5 cm. Its mass is 1.5 kg. Calculate the density of the metal.
A graduated cylinder contains 148 mL of water. A 11.0 g piece of iron (density = 7.86 {g/cm^3}) and a 19.0 g piece of lead are added. What is the new water level in the cylinder? Density of the lead is 11.3g/ml
The kinetic energy of the ejected electron is given by 1/2 mv2= h v -?. where m and v are the mass and velocity of the electron
The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive
A pound of coffee beans yields 48 cups of coffee. How many milliliters of coffee can be obtained from 1 g of coffee beans?
In the electrolysis of water, 2h20 yields 2h2 plus o2, if the volume of oxygen produced was 8ml, what would be the volume of hydrogen produced?
what is the pH of a solution formed by combining 200.0 mL of 0.16 M HCL with 300.0 mL of 0.091 M NaOH at 25 degrees celcius
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.
Plot pH values as a function of volumes of added KOH and suggest appropriate indicators for the titration.
