Answer:
The equilibrium will shift to the right
Explanation:
The chemical equilibrium represents a balance between direct and inverse reactions.
The Le Chatelier Principle states that variations in experimental conditions can alter this balance and displace the equilibrium position, causing more or less of the desired product to form. And in this way the system evolves in the opposite direction so as to counteract the effects of such disturbance.
The variation of one or more of the following factors are those that can alter the equilibrium condition:
-
Temperature
- The pressure
- The volume
- The concentration of reactants or products
In this case:
NaOH produces OH⁻ ions. OH⁻ ion uses up H₃O⁺ through the reaction:
H₃O⁺ + OH⁻ → 2 H₂O
According to the Le Chatelier principle, the addition of NaOH consumes one of the products, decreasing its concentration. Therefore, to balance the reaction, <u><em>the equilibrium will shift to the right</em></u> in order to counteract the effect that disturbed it and recover the equilibrium state.
It is B balance, because it has a 0,01 g divisions scale. The minimun division in A balance is only 0,1 g, i.e, decigram measurement.
Answer:
Explanation:
1. A student mixes baking soda and vinegar in a glass. The results are shown at left. ... Yes I do belive that new substances are being formed because there is a chemical reaction between the baking soda and vinegar turning it into a bubbly substances instead of a powder and liquid.
Answer:
Tectonic plates
Explanation:
Tectonic plates shifting is long term which creates a short term Earthquake, I hope this helped.
K is in the first group can form ion K⁺,
N is in third group can form negative ion (8-5=3) N³⁻
