Seasickness. The symptoms of carbon monoxide poisoning mimic the symptoms of seasickness.
Answer:
Lithium chloride (LiCl), carbon dioxide, and water
Explanation:
Li₂CO₃ + HCl ⇒ LiCl + CO₂ + H₂O
When lithium carbonate reacts with hydrochloric acid, lithium chloride, water, and bubbles of carbon dioxide gas are given off. This is the result of a double displacement reaction followed by a decomposition reaction.
Hope that helps.
Answer:
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Explanation:
First of all, identify the first and last steps before figuring out the middle.
In order, the first and last steps should be
Define the Problem
...
Draw a Conclusion.
Next, you can add your answers in the middle, from beginning to end. That would be,
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Let me know if this is inaccurate as I am learning everyday. Hope this helped!
The deltaHrxn = -243 kJ/mol the deltaHrxn of CH4(methane) = -802 kJ/mol
The fuel that yields more energy per mole is METHANE. The negative sign merely signifies the release of energy. Thus, 802 kJ/mol is greater than 243 kJ/mol.
The fuel that yields more energy per gram is HYDROGEN. Here is the computation:
deltaHrxn = (-243 kJ/mol)(1 mol/2.016 g H2) <span>= -120.535714286 kJ/g or -121 kJ/g
</span>deltaHrxn of CH4(methane) = (-802 kJ/mol)(1 mol/16.04 g)
<span>= -50 kJ/g
</span>
As discussed the negative sign serves as the symbol of released energy. Thus, 121 is greater than 50.
