Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.
Hope this sheds some light ♥︎
The mixture can be separated as shown in the flow chart
Answer is: a.2h2(g) + o2(g) 2h2o(g) + 483.6 kj.
Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.
The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.
Balanced chemical reaction: 2H₂ + O₂ → 2H₂O ΔH = 483.6 kJ.
There are four hydrogen atoms and two oxygen atoms on both side of balanced chemical reaction.
Answer: The vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor that is in thermodynamic equilibrium with the condensed phase (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of the evaporation rate of a liquid.
Explanation:
Mountain chains are formed by the action of different tectonic plates drifting
