In a reaction 82.00 g of sodium reacts with 74.00g of ferric oxide to form sodium oxide and iron metal. calculate the mass of solid iron produced.
One company introduces carbonate by bubbling carbon dioxide into water until CT=10-3 M (equivalent to adding "H2CO3*" until CT = 1 x 10-3 M), a second adds sodium bicarbonate (NaHCO3) until CT = 10-3 M, and a third adds sodium carbonate until CT=1..
the specific heat of ethylene glycol is 2.42 j/k-g. How many j of heat are needed to raise the temperature of 62.0 g of ethylene glycol from 13.1°c to 40.5°c?
The current concentration of carbon dioxide in the atmosphere is 378 ppmv. Annual anthropogenic additions to the atmosphere are about 8 Gt (as C) of which about 4 Gt are removed into the oceans and terrestrial environment.
