H₂SO₄ + Ba(OH)₂ -----> BaSO₄ + 2H₂O
Coefficient for sulfuric acid: 1
Answer: This is hard to do accurately, but here is my best assessment.
Explanation:
Experiment: B - describes how the experiment was done
Conclusion: A - The data support the prevailing hypothesis
Research: D - This is what we analyzed
Analysis: C - We compared the data
To convert boiling water to steam, that would involve heat of vaporization. The heat of vaporization for water at atmospheric conditions is: ΔHvap = <span>2260 J/g.
Molar mass of water = 18 g/mol
Q = m</span>ΔHvap = (1.50 mol water)(18 g/mol)(<span>2260 J/g) = 61,020 J
Time = Q/Rate = (61,020 J)(1 s/20 J) = 3051 seconds
In order to express the answer in three significant units, let's convert that to minutes.
Time = 3051 s * 1min/30 s = <em>102 min</em></span>
Answer:
C. Digestion is the answer.
Answer:
16
Explanation:
4 nitrogen (N) atoms and 12 (3×4) atoms in Hydrogen (H)
Total = 4 + 12 = 16 molecules
