When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. It could be A I’m not sure if this helps.
You need to use the equation PV = nRT
The only “trick” in these problems is you need to use the correct UNITS. Especially for the “R” value.
If you get the units (eg temps in Celsius or Kelvin) corresponding to the correct “matching” units of the other variables.
You need to convert the temp into Kelvin first
Answer:
the energy should be potential
Answer:
D. Two substances mix evenly without reacting.
Explanation:
Solutions are homogenous mixtures of solutes and solvents.
- In a solution, the solute particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- It is usually present in smaller amount than the solvent
- The solvent is the dispersing substance that allows the solute to go into solution.
- The solute could be solid or liquid or gas
- The solvent could be solid or liquid or gas but most times liquid.
Answer:
The equilibrium will shift in forward direction.
Explanation:
The equilibrium between the carbonic acid and bicarbonate ion is shown below as:
H₂CO₃ (aq) ⇔ H⁺(aq) + HCO₃²⁻(aq)
According to Le Chatelier's Principle, the change in any state of the equilibrium say temperature, volume, pressure, or the concentration, the equilibrium will oppose these changes and will shift in such a way that the effect cause must be nullified.
<u>If a strong base is added to the equilibrium, the base will accept hydrogen ions which are formed in the right side of the equilibrium. Thus, there will be less hydrogen ions present and to compensate this effect, the equilibrium will shift in forward direction.</u>
