A balloon is inflated from 0.0100 L to 0.500 L against an external pressure of 10.00 atm. How much work is done in joules? 101.3 J = 1 L x atm
The initial temperature is 298k. The diameter of the cylinder is 0.5m. and the piston height is 1m. a. what is the mass of the weights on the cylinder
If 85.6 ml of a 6.75 M solution are diluted to 6.20 L with water, what is the concentration of the final solution
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base.
In the balanced redox reaction: 2C2H6(g) + 7O2(g) > 4CO2(g) + 6H2O(g), which species is oxidized
