Answer: My answer is in the explanation
Explanation:
Physical and mechanical characteristics of iceberg ice were studied from samples collected near the shores of eastern Newfoundland. Although the physical characteristics show considerable diversity, iceberg ice has some common features and is generally porous, lacks significant concentrations of dissolved materials, contains internal cracks and has an irregular interlocking grain structure.
Answer:
If two electrons in the same atom have the same value of "l", they are If two electrons in the same atom have the same value of "l", they are in the same orbital. in the same sublevel, but not necessarily in the same level. in different levels and in different shaped orbitals. in the same level, but different sublevel.
Answer:
2.5 moles of O₂ = 5 moles of H₂O
Explanation:
The balanced equation for the reaction is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Finally, we shall determine the number of mole of H₂O produced by the reaction of 2.5 moles of O₂. This can be obtained as follow:
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Therefore, 2.5 moles of O₂ will react to produce = 2.5 × 2 = 5 moles of H₂O.
Thus,
2.5 moles of O₂ = 5 moles of H₂O
