Answer:
Theoretical yield = 40.8g
Explanation:
4Al + 3O2 ----] 2Al2O3
<h3>if 27.0g of Al ----] 102.0g of 2Al2O3</h3><h3>therefore 10.8g -----] xg</h3>
10.8g×102.0g/ 27.0g
theoretical yield = 40.8 g
Answer:
C. The boiling point of water
Explanation:
The shape of the water and its rate of evaporation (including steam generation) will change across containers with different shapes, surface areas, and temperatures. The appropriate choice is the one shown above.
An ionic bond. covalent bonds do not conduct in a solid or a liquid state, ionic bonds conduct in a liquid state and not in a solid state.

The hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.
<h3>How to calculate [H3O+]?</h3>
The hydrogen ion concentration of a solution can be calculated as follows:
pOH = - log [OH-]
pOH = - log [6.3 × 10-⁷M]
pOH = - [-6.2]
pOH = 6.2
Since pOH + pH = 14
pH = 14 - 6.2
pH = 7.8
pH = - log [H3O+]
7.8 = - log [H3O+]
[H3O+] = 10-⁷:⁸
[H3O+] = 1.5 × 10-⁸M
Therefore, the hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.
