Baking soda (sodium bicarbonate) is a
compound commonly used in baked
goods, as a deodorizer in refrigerators,
and as an antacid, Commercial quantities
of baking soda are produced by mixing
soda ash dissolved in water with carbon
dioxide. Baking soda precipitates as a
solid from this method:
Na2CO3 + CO2 + H20 - 2 NaHCO3
How many grams of soda ash would be
needed to produce 1.00 kg of sodium
bicarbonate?

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
