In 1994 it was proposed (and eventually accepted) that element 106 be named seaborgium, Sg, in honor of Glenn T. Seaborg, discoverer of the transuranium elements. a. 263Sg was produced by the bombardment of 249Cf with a beam of 18O nuclei. Complete and balance an equation for this reaction. b. 263Sg decays by emission. What is the other product resulting from the decay of 263Sg?
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
Finding the Heat of Reaction (Enthalpy) from Heats of Formation, Calculate the heat of reaction at the standard reference state for the following reactions
Using the mole balance equation only, a relationship between conversion in the reactor and the reactor temperature can be obtained. This relationship is shown in the following figure as a plot of XMB versus reactor temperature.
upon responding to a 200 a.m. domestic transportation mishap your hazmat team determines that a liquefied compressed
Design a reactor system to produce 40 metric tons per year of riboflavin using the strain given in the patent.
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
Explain the term "Selectivity" and "Yield".Selectivity is defined as the ratio of moles of desired product to moles of undesired product.Yield is defined as the ratio of moles of product formed to moles of reactant eitherfed or consumed and What a..

Coal gasification is carried out at 850 °C and 40 atmospheres pressure, by reaction of coal with steam and oxygen. The empirical formula of the coal is roughly CH0.8S0.013. What materials of construction would you recommend for:
If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Represent this change using symbols for the elements, and write out the balanced equation.
Calculate the work done in the isothermal reversible expansion of one mole of CH4 (g) from 1.00 dm3 to 10.00 dm3 at 300 K. Treat methane as a van der Waals gas. The van der Waals gas constants for methane are: a=2.3026 dm6⋅bar⋅mol−2 and b=0.043067 dm..
