Hyperventilation<span> will blow off carbon dioxide which reduces the alkaline component of the </span>blood<span>, resulting in acidosis and a lower </span>blood pH<span>. (See Andromeda Strain). This is why re-breathing into a bag to increase carbon dioxide in your </span>blood will make you feel less faint. Basically <span>It increases the pH ... you can look at CO2 as an acid ... and when reduced ... alkalinization of the pH occurs</span>
Answer:
c. Hfus is always negative.
Explanation:
Because energy is released when fusing solids
Answer:
D.) 2 H₂ + O₂ -----> 2 H₂O
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of the reaction. If these amounts are unequal, coefficients can be added to modify the amount of particular molecules.
A.) Not balanced
2 H₂ + 2 O₂ -----> H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
B.) Not balanced
2 H₂ + 2 O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 4 oxygen
<u>Products</u>: 4 hydrogen, 2 oxygen
C.) Not balanced
H₂ + O₂ -----> H₂O
<u>Reactants</u>: 2 hydrogen, 2 oxygen
<u>Products</u>: 2 hydrogen, 1 oxygen
D.) Balanced
2 H₂ + O₂ -----> 2 H₂O
<u>Reactants</u>: 4 hydrogen, 2 oxygen
