Answer:
0.20 mol's
Explanation:
1.675 L = 1.675 dm^3
moles = V/(conc):
moles = 1.675/(8.5)
moles = 0.1970... --> 0.20
Answer:
Double replacement.
Explanation:
Chemical Reactions => Double Replacement Reactions.
Let's call Ted as T, Emily as E, Jack as J, and Brenda as B.
In the first match, we have T and E playing against J and B; and in the second match, we have T and B playing against J and E. We can state a 'reaction' of this if the first match would be the reactants and the second match the products:

You can note that this is similar to a double replacement reaction, remember that a double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:

which is similar to the reaction of the game, so the answer would be Double replacement.
Deforestation....trees release water vapour..with the trees being cut down less water vapour is being released..
consuming the water.... we use up water for drinking and for our homes etc...
hope this helps!
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>
