15.63 mol. You need 15.63 mol HgO to produce 250.0 g O_2.
<em>Step 1</em>. Convert <em>grams of O_2 to moles of O_2</em>
Moles of O_2 = 250.0 g O_2 × (1 mol O_2/32.00 g O_2) = 7.8125 mol O_2
<em>Step 2</em>. Use the molar ratio of HgO:O_2 to convert <em>moles of O_2 to moles of HgO
</em>
Moles of HgO = 0.8885 mol O_2 × (2 mol HgO/1 mol O_2) = <em>15.63 mol HgO</em>
Answer:
skeletal and circulatory
Explanation:
The skeletal system works with the muscular system to help the body move. Marrow, which is soft, fatty tissue that produces red blood cells, many white blood cells, and other immune system cells, is found inside bones.
The circulatory system consists of the heart and blood vessels which emcompasses all of the arteries, veins, and capillaries. The arteries carry oxygenated blood away from the heart, and veins return deoxygenated blood back to the heart. The main purpose of the circulatory system is to transport blood, oxygen, nutrients and hormones to and from different cells and tissues throughout the body. This system works hand-in-hand with the respiratory system to facilitate the exchange of oxygen and carbon dioxide within the blood per the alveoli in the lungs. It is also very important for the the removal of wastes and poisons within the body via the digestive and urinary systems.

Aluminum chloride is formed in the reaction of aluminum with hydrochloric acid. The formula of aluminum chloride is AlCl₃.
Aluminium chloride, additionally referred to as Aluminium trichloride, is an inorganic compound with the formula AlCl₃. It bureaucracy hexahydrate with the system [Al(H₂O)₆]Cl₃, containing six water molecules of hydration. Each are colourless crystals, however samples are regularly contaminated with iron(III) chloride, giving a yellow shade.
Aluminum Chloride is used to control immoderate sweating. This medicinal drug can be used for other purposes; ask your fitness care provider or pharmacist when you have questions.
