A gas-forming reaction produes 1.30 m3 of gas against a constant pressure of 178.0 kPa. Calculate the work done by the gas in joules.
The sum of the third and the fourth terms is 48. If the terms of the geometric progression are alternately positive and negative, then the first term is?
a 0.456 gram sample of an unknown mono- protic acid lets call it hz was dissolved in some water you pick the amount.
Which reagent is used in excess? How great is the molar excess (how many times greater)? I'll add the procedure images in the comments
A researcher working on a batch of a ceramic material tested two sets of samples for fracture strength. For one set of samples the specimens were tensile bars with a 10x10x100 mm^3 tensile gauge section
The NaOH catalyst solution is prepared by dissolving 0.4 g of NaOH in 4.0 mL of water then adding 3.0 mL of 95% ethanol. how many moles of NaOH, mL of water and ml of ethanol in 3 mL?
How do I find the volume of that solution so I can find the concentration of Cl after titration?
Explain for which of the following species is resonance an important property: HONO, HONO2, N3-, NO2-, NO2
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
