Answer:
I don't really get what were supposed to be answering. if you give us a more clear question, it will be easier to answer! :)))
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.
HA = Acid
= Base
= Conjugate base
= Conjugate acid
For example:
Sulfuric acid dissociating in its solution to form conjugate base and conjugate acid.
Sulfuric acid = Acid
= Base
= Conjugate base
= Conjugate acid
Sugar dissolves and is spread throughout the glass of water<span>. The </span>sand<span> sinks to the bottom. The sugar-</span>water<span> is a homogeneous mixture while the </span>sand-water<span> is a heterogeneous mixture. Both are mixtures, but only the sugar-</span>water<span> can also be called a </span>solution. i got this from :<span>www.chem4kids.com/files/matter_solution.html

Answer: compaction, and cementation.
Explanation:
Answer:
167 kJ
Explanation:
Given parameters
Change in enthalpy = 130 kJ (decrease)
Work done = -137 kJ
Change in energy, \delta = ?
From the first law of thermodynamics:
ΔH = ΔE + PΔV,
Where, ΔH= change in enthalpy
ΔE = change in Internal energy
Substituting values into the above formula —
130 kJ = ΔE + -137 kJ
130 kJ = ΔE - 137 kJ
therefore,
ΔE = (130 + 137 ) kJ
ΔE = 167 kJ
Therefore, the change in energy of the gas mixture during the reaction is 167 kJ.
Since the value of energy change Is positive, therefore this Is endothermic reaction
