Explanation:
Answer: The starting pressure of is 1.39 atm.
Explanation:
Initial p 0 0
eq'm p-x 0 2x
Total pressure at equilibrium = p - x + 2x = p + x = 1.9...(1)
...(2)
Solving equation (1) and (2). we get x = 0.51
p + x = 1.9
p= 1.9 - 0.51 = 1.39 atm
The starting pressure of is 1.39 atm.
To melt a solid, energy must be input into the solid to give the molecules high energy to disrupt the lattice bonds and change phase. To return the liquid to solid, the same amount of energy used in melting is required to be removed from the liquid, ideally. This is assuming there is no loss of energy in the process.
Answer: Alcohol
Explanation:
A neutralization reaction involves the combining of an acid and a base to create a salt and water. Reactants = acid + base. Products = salt + water. No alcohol is involved with a neutralization reaction.
Explanation:
The reaction can be said to be a single replacement reaction if one substance in a chemical reaction is replacing another one.
For example:
A + BC → AC + B
In such reactions there is a replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in solution.
The relative positions of the two elements in the activity series provides the driving force for a single replacement reaction. If one element that is to replace another in a compound is more active, the reaction will occur. If it is less reactive, there will be no reaction.
