Answer:
The percentage loss in mass between sucrose solutions 0.5 mol/dm³ and 0.1 mol/dm³ is 80.0% loss in mass
Explanation:
The molecular formula of sucrose is C₁₂H₂₂O₁₁
The molecular mass of sucrose is 342.3 g/mol
Therefore;
The mass of sucrose in 0.1 mol/dm³ solution = 0.1 × 342.3 = 34.23 g
The mass of sucrose in 0.5 mol/dm³ solution = 0.5 × 342.3 = 171.5 g
The percentage loss in mass of the sucrose is given as follows;
Therefore;
Which gives, the percentage loss in mass between sucrose solutions 0.1 mol/dm³ and 0.5 mol/dm³ is 80.0% to three significant figures.
Answer:
<h2>Capillaries interact with the respiratory system through the <u>alveoli</u> present in the lungs.</h2>
Explanation:
Lungs and capillaries are important parts of respiratory system which allows the process of breathing through which living body take in oxygen from the atomsphere. The lungs bring oxygen into the body and the process is called inhalation and releases carbon dioxide out of the body and the process called exhalation.
The walls of capillaries are in contact with the walls of alveoli, When the person breath in it takes oxygen, the oxygen transferred to the red blood cells and it further releases carbon dioxide. The oxygenated blood is then move to the heart and other body parts from the lungs.
Hence, this is how the capillaries interact with the respiratory system.
When the chef says to leave the “celery and lettuce, soaking in water prior to making a salad” the transportation the water goes through is the xylem. Plants pulls water upward through xylem tubes.
Arteriolar blood pressure increases in response to
Adrenaline hormome secreted by Adrenal gland in case of emergency or in do or die conditions.
when this hormone is secreted blood pressure and heart beat increases. more blood is directed towards skeletal system that allows us to face the problem.
