Without doing any calculations determine what the sign of delta s will be for the following equation 2CO(g)+O2(g)>>>2CO2 (g) that's all we were given and i'm not sure how to solve without any additional information.
What is the change in the boiling point of the aqueous solution? and water how man moles of ions are present is solution
Calculate the enthalpy change for the production of 200 L of hydrogen at 500 torr and 338.15 K for reaction : C(s) + H2O (g) --> CO (g) + H2 (g)
If the Ecell measures 1.40 V, what is a more accurate molar concentration of Cr3+, assuming the molar concentration of Ag+ is accurate. What is the sign of the cathode in a galvanic cell. What type of reaction occurs at the cathode.
The solution's boiling temperature is 103.25 degrees celsius. What is the molar mass of this molecular compound?
Identify the compound: molecular mass 113; gives a positive hydroxamate test, which indicates the presence of either an acyl chloride or an ester
Integrate the expression b = 1/V (derivative of V / derivative of T) at constant pressure, assuming that b is independent of temperature. By doing so, obtain an expression for V as a function of T and b at constant P. b means beta
Give an example of a biological reaction in which water participates as a reactant and a reaction in which it participates as a product.
How many grams of CO are needed to react with an excess of Fe2O3 to produce 209.7g Fe? Fe2O3(s) + 3CO(g) -> 3CO2(g) + 2Fe(s)
calculate the ph that results when 100 mL a liquot of 0.0500 M is added to 400 M of a NH3/NH4+ buffer that is 0.200 M in NH3 and 0.300 M in NH4Cl
Cyanogen is a gas which contains 46.2 % C and 53.8 % N by mass. At a temperature of 25oC and a pressure of 750 mmHg, 1.50 g of cyanogen occupies 0.714 L.
Why does phenolphtalein change colour during the production of gas?
Elements in the first short period are limited by the octect rule whereas those in the higher period can expand their valence shells. Describe what this means, account for this phenomenon and give an example of each.
