Answer:
a) equilibrium shifts towards the right
b) equilibrium shifts towards the right
c) equilibrium shifts towards the left
d) has no effect on equilibrium position
e) has no effect on equilibrium position
Explanation:
A reversible reaction may attain equilibrium in a closed system. A chemical system is said to be in a state of dynamic equilibrium when the rate of forward reaction is equal to the rate of reaction.
According to Le Chateliers principle, when a constraint such as a change in temperature, pressure, volume or concentration is imposed upon a system in equilibrium, the equilibrium position shifts in such a way as to annul the constraint.
When the concentration of reactants is increased, the equilibrium position is shifted towards the right hand side and more products are formed. For an endothermic reaction, the reverse reaction is favoured by a decrease in temperature. Increase in pressure has no effect on the system since there are equal volumes on both sides of the reaction equation. Similarly, the addition of a catalyst has no effect on the equilibrium position since it speeds up both the forward and reverse reactions to the same extent.

Vinegar with cabbage juice would change the color to red so its C
Answer:
<h2>75 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 5 × 15
We have the final answer as
<h3>75 g</h3>
Hope this helps you
The opinions of Aristotle and Democritus are not considered scientific theories because they were not empirical.
Science is empirical in nature. It depends on evidences obtained from rigorous experiments.
However, Aristotle and Democritus and were philosophers whose opinions were based on reasoning rather than empiricism.
Since their opinions were not empirical, they are not considered scientific theories.
