How many grams of water can be made from 6 moles of oxygen
Andrew [12]

12 moles H2O

Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.

5. You have two sealed jars of water at the same temperature. In the first jar there is a large amount of water. In the second j
Aneli [31]
The vapor pressure of the two jars are the same.

The volume of water inside the container does not change the vapor pressure.

As long as the liquid remains being water and the temperature does not change the vapor pressure will be the same. The vapor pressure depends only in the nature of the substance and the temperature of the system.
If you want to know more about this, i.e. why, here you have additional explanation:

The vapor pressure is the pressure of the vapor of a substance in equilibrium with the substance in liquid (or solid state) and it is due to the fact that some molecules in the liquid (or solid), those that are close to the surface of liquid in contact with the gas phase and that have enough kinetic energy, evaporate.

At equilibrium the number of molecules passing from the liquid state to the gas state is equal to the number of molecules that pass from the gas state to the liquid state.  If the volume of liquid is increased or decreased, as long as the temperaature of the system remains constant the equilibrium is reached again with the same vapor pressure.

Hay particulas mas pequeñas que el atomo?
svp [43]

Answer:

Una partícula subatómica es aquella que es más pequeña que el átomo. Puede ser una partícula elemental o una compuesta, a su vez, por otras partículas, como los quarks que componen los protones y los neutrones. ... De esta manera, se han descubierto docenas de partículas subatómicas, y se teorizan cientos de otras más.

At 45 C the volume of a certain gas is 27.5 L
wariber [46]
Regretfully, I do not know what is asked of the problem because it is not stated above. However, it is easier to answer any question pertaining to the temperature, volume, and pressure of gases by assuming that they behave ideally. With this, we'll be able to use the ideal gas law which is mathematically expressed as,
                                       PV = nRT
where P and V are pressure and volume, respectively. n is the amount of material in mol, R is gas constant, and T is temperature.
