Claim: The aluminum boat will float
Evidence: A foil boat has less density over more space
Reasoning: Since the boat has little density the boat has the ability to float
This is true, this isn't a question, it's a fact.
Answer:
67.1%
Explanation:
Based on the chemical equation, if we determine the moles of sodium carbonate, we can find the moles of NaHCO₃ that reacted and its mass, thus:
<em>Moles Na₂CO₃ - 105.99g/mol-:</em>
6.35g * (1mol / 105.99g) = 0.0599 moles of Na₂CO₃ are produced.
As 1 mole of sodium carbonate is produced when 2 moles of NaHCO₃ reacted, moles of NaHCO₃ that reacted are:
0.0599 moles of Na₂CO₃ * (2 moles NaHCO₃ / 1 mole Na₂CO₃) = 0.1198 moles of NaHCO₃
And the mass of NaHCO₃ in the sample (Molar mass: 84g/mol):
0.1198 moles of NaHCO₃ * (84g / mol) = 10.06g of NaHCO₃ were in the original sample.
And percent of NaHCO₃ in the sample is:
10.06g NaHCO₃ / 15g Sample * 100 =
<h3>67.1%</h3>
1.) No we are not alone in the universe.
2.) We are the only species on this planet with the foresight capable of deliberately plotting a path toward a desirable long-term future. Plan it for the apes; because they can’t.
3.) the state of being awake and aware of one's surroundings.
4.) Dreams are basically stories and images our mind creates while we sleep. ... Dreams can occur anytime during sleep. But most vivid dreams occur during deep, REM (rapid eye movement) sleep, when the brain is most active.
5.) Definition of Solar Energy. When the sun's energy reaches the earth in the form of sunlight, it can be converted into other forms of energy. The sun is a huge ball of gas, mostly hydrogen with a little helium.
