Answer:
B. Indicator
Explanation:
An indicator is used to determine whether an acid or alkali has been added to a solution.
Indicators can be liquid or a paper called litmus paper. There also some digital forms of indicators that can tell whether an acid or alkali has been added to a solution.
- An acid and alkali will change the pH of a solution.
- pH is the amount of hydrogen ions that are in a solution
- So, these changes in the pH when an acid or alkali is introduced is usually monitored using indicators.
- Examples of indicators are litmus paper, methyl orange, methyl red, bromothymoblue
H2O is the Bronsted-Lowry base because it accepts the hydrogen ion to become H3O after the reaction is complete.
As per Le Chatelier principle, when a system in equilibrium is disturbed, the reaction will try to compensate the change to restore the equilibrium.
This reaction occurs in gas phase, so the volume is inversely proportional to the pressure.
Then a decrease in volume will cause an increase in pressure, so the system will tend to react in the direction that compensates this increase, this is the system will try to reduce the number of moles of particles to reduce the increase of the pressure.
As you see, there are 3 particles of products (2 of NO and 1 of Br) for every 2 particles of reactant (NOBr).
That means, that the equilibrium will displace to the left, this is the concentration of NOBr will increase while the concentration of NO and Br will decrease.
Answer : attention swung away from renewable sources as the industrial revolution ... turbines have developed greatly in recent decades, solar photovoltaic technology is ... However, the variability of wind and solar power does not correspond with ... and 0.17 for solar PV, hence declared net capacity (DNC) is the figure
