Dear friend,
Because the water remains water throughout this process, it is not undergoing any chemical change. There is no new substance or element added but only a change of form.
Answer:
Having too much carbon dioxide in the body can cause nonspecific symptoms like headache, fatigue, and muscle twitches. Often, it clears up quickly on its own. With severe hypercapnia, though, the body can't restore CO2 balance and the symptoms are more serious
Explanation:
Answer:
6.)
7.) 134.4 g O₂
Explanation:
The unbalanced equation:
NH₃ (g) + O₂ (g) ---> N₂ (g) + H₂O (g) + energy
<u>Reactants</u>: 1 nitrogen, 3 hydrogen, 2 oxygen
<u>Products</u>: 2 nitrogen, 2 hydrogen, 1 oxygen
The balanced equation:
4 NH₃ (g) + 3 O₂ (g) ---> 2 N₂ (g) + 6 H₂O (g) + energy
<u>Reactants</u>: 4 nitrogen, 12 hydrogen, 6 oxygen
<u>Products</u>: 4 nitrogen, 12 hydrogen, 6 oxygen
To convert from moles to grams, you need to multiply the starting value (4.2 moles) by the molar mass (32.00 g/mol). The molar mass can serve as a conversion because it technically means there are 32.00 grams O₂ per every 1 mole. It is important to arrange this ratio in a way that allows for the cancellation of units (the desired unit should be in the numerator).
4.2 moles O₂ 32.00 g
-------------------- x ---------------- = 134.4 g O₂
1 mole
The answer is gonna be the last one :)
