Arrange the following gases, at the temperature indicated, in order of increasing rms speed of the particles: helium at 100 degrees C, neon at 50 degrees C, and argon at 0 degrees C.
When a neutralization reaction was carried out using 100 ml of .7890 NH3 water and 100 ml of .7940M acetic acid change in temperature was found to be 4.76 degress C. Specific heat of reaction mixture was 4.104 J g-1 K-1 and density was 1.03 g mL-1..
if a 1.223 g sample of aluminum metal is heated in a chlorine gas atmosphere the mass of aluminum chloride produced is
Twenty-five milliliters of liquid nitrogen (density = 0.807 g/mL) is poured into a cylindrical container with a radius of 11.0 cm and a length of 20.0 cm. The container initially contains only air at a pressure of 760.0 mmHg (atmospheric pressure)..
A chemical reaction was used to produce 1.96 moles of copper (II) bicarbonate, Cu (HC03)2. What mass of copper (II) bicarbonate was produced
2 l of 7 m concentrated hf solution is placed into a 10 lcontainer. the container is sealed and the air is evacuated.
calculate the number of grams of acetic acid per 10ml of the vinegar. Since vinegar has a density of about 1.00 gram/ml, 100 ml eighs about 100 g.
Calculate the volume of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
If 0.250 mole of hydrogen gas occupies 0.333 L at 20 degrees Celcius, what is the pressure in mmHg
If these two samples are mixed and then compressed in a 1.3 L vessel, what is the final pressure of the mixture. Assume that the temperature remains unchanged.
chlorine has two naturally occurring isotopes35cl isotopic mass 34.9689 amu and 37cl isotopic mass 36.9659 amu. if
The measured potential was 0.0330 V. What is the concentration of X when the potential is 0.0480 V? Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of X is 1.
Zinc carbonate hydroxide contains 59.55% zinc by mass. Calculate the molecular weight (molar mass) of zinc carbonate hydroxide (there are 5 unites of zinc in every unit of zinc carbonate hydroxide
