Answer:
How do you find pressure given moles volume and temperature?
Therefore, to convert the moles of gas to pressure, the scientist must know the volume and temperature of the gas, in addition to the number of moles of gas. The pressure is then given by P = nRT / V.
Answer:
pressure
Explanation:
Boyle's law states that "the volume of a given mass of gas is inversely proportional to the pressure provided the temperature remains constant"
Reducing agent is an compound/atom, that loses an electron and is oxidized.
0.........+I.............+II............0
Ca + 2HCl ----> CaCl₂ + H₂
Calcium is oxidized --- it's reducing agent (reductant).
Hydrogen is reduced --- HCl is oxidizing agent.
Answer:
D
Explanation:
A reaction that is exothermic and causes a decrease in the entropy of the system cannot be a spontaneous reaction. This is not totally true because naturally For a spontaneous process, the entropy of the universe (system plus surroundings) must increase. This is the 2nd law of thermodynamics. The system entropy can decrease as long as the entropy of the surroundings increases enough to make the sum of the system and surroundings positive.
And we know that a spontaneous reaction is a reaction that occurs in a given set of conditions without intervention. Spontaneous reactions are accompanied by an increase in overall entropy or disorder. If the Gibbs Free Energy is negative, then the reaction is spontaneous, and if it is positive, then it is nonspontaneous.
