Answer: Do you take Ms. Reyes
Explanation: The answer is Outside air, Nose, Lungs, Bloodstream, Cell
Answer:
In the presence of UV light, ethane will react with bromine in a substitution reaction. UV light is the condition under which the reaction will occur so it is written above the arrow in the chemical equation. As the reaction proceeds, the intensity of the re-brown colour of the bromine water decreases.
pH of 1 is Red
pH of 13 is Yellow
Explanation:
Indicators are substances which change color to signal the end of an acid-base reaction as required by the balanced chemical equation of the reaction.
Examples are:
- methyl orange
- methyl red
- phenolphthalein
- litmus
- cresol red
- cresol green
- alizarin R3
For methyl red:
pH 1 is acidic and its red
pH 13 is basic and it is yellow
pH 7 is neutral and it is orange

Answer:
ii. < iv. < i. < iii.
Explanation:
Hello,
At first, the entropy is lower in solid-phase systems since their particles are molecularly closer. Next, by knowing that the higher the temperature, the higher the entropy, the gaseous HCl at 25 ºC occupies the second place. After that, it is clear 2 moles of HCl have more entropy than just 1 since the larger the amount of mater the higher the entropy.
Best regards.
