Foods cook faster when placed in a pressure cooker. This is because the pressure on the surface of the water is (higher than/low
tia_tia [17]

Answer:

The pressure is higher than the atmospheric one, therefore the temperature is less.

Explanation:

When it is closed permanently, the pressure of the pot inside it increases, generating that the atoms and particles of the water are closer together, increasing their kinetic energy, if intermolecular friction and therefore the boiling point is lower, because the water reaches a boil or boil at a lower temperature.

How many moles of O2 molecules should be supplied to burn 1 mol of CH4 molecules in a domestic furnace?
Sati [7]
The combustion of 1 mole of methane (CH4) in a domestic furnace requires 2 moles of O2 molecules, assuming the combustion was complete or ideal. To solve this problem, use stoichiometry of the reaction's balanced chemical equation:

CH4 + 2O2 --> CO2 + 2H2O

The ratio of CH4 to O2 in terms of moles is 1:2. So 1 mole of CH4 needs 2 moles of O2.

Consider the combustion of h2(g) 2h2(g)+o2(g)→2h2o(g). If hydrogen is burning at the rate of 0.49 mol/s, what is the rate of con
mamaluj [8]

Answer : The rate of consumption of oxygen = 0.245 mol/s

Solution :  Given,

                 Rate at which Hydrogen burns = 0.49 mol/s

                 The Reaction is,

                       2H_{2}(g)+O_{2}(g)\rightarrow 2H_{2}O(l)

    In this reaction,  2 moles of hydrogen react with the 1 mole of oxygen.

    The rate at which oxygen burns is equal to the half of rate at which hydrogen burns.

     Rate at which Oxygen burns = \frac{1}{2} × 0.49 mol/s

                                                      = 0.245 mol/s
