The simplest formula is C₅H₁₀O.
We must calculate the masses of C, H, and O from the masses given.
<em>Mass of C</em> =5.63 g CO₂ × (12.01 g C/44.01 g CO₂) = 1.536 g C
<em>Mass of H</em> = 2.30 g H₂O × (2.016 g H/18.02 g H₂O) = 0.2573 g H
<em>Mass of O</em> = Mass of compound - Mass of C - Mass of H
= (2.20 – 1.536 – 0.2573) g = 0.406 g
Now, we must convert these masses to moles and find their ratios.
From here on, I like to summarize the calculations in a table.
<u>Element Mass/g Moles Ratio Integers </u>
C 1.536 0.1279 5.038 5
H 0.2573 0.2553 10.05 10
O 0.406 0.0254 1 1
The empirical formula is C₅H₁₀O.
Answer:
Yes, Democritus's atomic theory was correct.
Explanation:
He thought the first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties. The other scientists added onto his theory to show that he was correct, except Aristotle, he thought the world was made of the 4 elements: earth, wind, fire, water.
Answer:
3
Explanation:
A cyclic event is one that happens repeatedly.
The appearance of Hailey's Comet is a cyclic event because it has happened in various occasions in the past on a regular schedule as predicted. We have every reason to believe that the appearance of Hailey's Comet every 75 years will continue to be happen until the comet ceases to exist.
I think the answer is C for this question
Answer: Ice is melting due to the transfer of thermal energy from Jan's hand to ice.
Explanation: The melting of ice is a physical change and is happening when the thermal energy from Jan's hand is transferred to ice. Due to this energy transfer, the particles of ice starts to move faster and hence, making the ice melt.
In this, the physical state of ice is changing from solid to liquid state.
