Answer:
Neutral solution, pH of 7.
Explanation:
Red cabbage is a natural indicator which gives red color when an acid is added, green color when a base is added and <u>it gives blue color when a neutral solution is added. </u>
<u>Given that when some red cabbage indicator is added to a solution , it turns blue which means that the solution is a neutral solution. Neutral solution have a pH of 7.</u>
The correct answer is : Circulatory and respiratory.
This condition primarily affects Caroline's circulatory system. Since the main purpose of the circulatory system is to supply the rest of the body with oxygen, this condition is greatly reducing the effectiveness of the circulatory system.
The decrease in oxygen supply to the lungs causes the reduction of the respiratory system effectivness as well, since the lung cells need oxygen for their metabolic processes.
Mass of H_2SO_4 required
Molarity
- Moles of solute/Volume of solution in L
So
- 0.1=n/0.1L
- n=0.1(0.1)
- n=0.01mol
Now molar mass of H_2SO_4
- 2(1)+32+4(16)
- 2+32+64
- 98g/mol
Mass
Answer:
evaporation or distillation
