In the circulatory system heart is the key organ. Through circulatory system transport of nutrients, gases such as oxygen to the body and nitrogenous waste away from the body. Human blood circulation is a double circulation as flood flows through two routes that is one for oxygenated blood and the other for deoxygenated blood.

The parts of the circulatory system in the diagram is given below:

a. Pulmonary artery, carries deoxygenated blood to the lungs from heart.

b. Aorta, carries oxygenated blood to the body tissues from the heart.

c. Inferior vena cava, carries deoxygenated blood from body tissues to the heart.

d. Arterioles, supplies oxygenated blood to the body cells.

If the concentration of the stock (provided) Cu(NH3)42 was 0.041 M, what concentration will the Cu2 be in beaker?

kodGreya [7K]

Answer:

$[Cu^{2+}]=0.041 M$

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of the solute and the volume of solution, given that the concentration of Cu(NH₃)₄²⁺ is 0.041 M, and there is only one copper atom per Cu(NH₃)₄²⁺ ion, we can compute the concentration of Cu²⁺ as shown below:

$[Cu^{2+}]=0.041\frac{molCu(NH_3)_4^{2+}}{L}*\frac{1molCu^{2+}}{1molCu(NH_3)_4^{2+}} =0.041 \frac{molCu(NH_3)_4^{2+}}{L}$

$[Cu^{2+}]=0.041 M$

Best regards!

Answer: The bubbles produced are most likely due to oxygen.

Explanation:

Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

The balanced chemical reaction for photosynthesis is:

$6CO_2+6H_2O\rightarrow C_6H_{12}O_6+6O_2$

Thus the bubbles produced are most likely due to oxygen.
