State dalton's law of partial pressures. use your text or other reference to find the partial pressure of water at 25, 26, and 27°c and record those values. a gas sample was collected over water at 25°c. the total pressure is determined to be 0.97 atm. what is the partial pressure of the gas that was collected? how many grams of bircarbonate will produce 40 ml of co2 gas? how many moles of gas are present when you collect 35.83 ml of the gas over water at 25.3°c and 0.97 atm? when bicarbonate is reacted with acid it releases co2. how many moles of hco, did you start with if you collect 1.24 x 103 moles of co2(g)? 3. 4. 5. 6. what is the molar mass of bicarbonate? 8. a 0.3459 g tablet that contains bicarbonate generates 1.24 x 10 moles of co2. what is the percent bicarbonate in the tablet?

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
