What is the correct cell notation for the reaction shown below?
3Zn2+(aq) + 2Al(s) → 2Al3+(aq) + 3Zn(s)
A metal sample weighing 40.0 g and at a temperature of 99.1 C was placed in 38.6 g of water in a calorimeter at 25.0 C. The calorimeter reached a maximum temperature of 32.8 C.
Assume air in tank is mixed and that air is an ideal diatomic gas. For a heated tank what heat rate must be applied to keep the tank air temperature constant? For a perfectly insulated tank, what is the tank air temperature after 100 seconds? The ..
Heat is now added until the water reaches a saturated vapor state. Find the initial volume, final pressure, work, and heat transfer. Any help would be appreciated, thanks in advance.
