Answer:
Explanation:
Hello,
In this case, since the carbon of the initial compound is present in the carbon dioxide product, we can compute the mass and moles of carbon in the compound:
Next, the mass and moles of hydrogen in the compound, is contained in the yielded amount of water, thus, we compute the mass and moles of hydrogen in the compound:
In such a way, the mass of oxygen comes from the mass of the compound minus the mass of carbon and oxygen:
And the moles:
Then, we compute the subscripts by diving the moles of C, H and O by the moles of oxygen as the smallest moles:
After that, we write:
Which must be shown in whole number only, thereby we multiply the subscripts by 2, so the empirical formula turns out:
Best regards.
Explanation:
Saturated solid/liquid solution is changed to an unsaturated solution by the dilution process.
When the saturated solution is diluted by addition large quantity of solvent it changed to an unsaturated solution.
Saturated solid/liquid solution can also be changed to an unsaturated solution by increasing the temperature or heating the solution.
A saturated solution is a solution where further solute will not dissolve in the solvent.
An unsaturated solution is a solution in which has the ability to dissolve more solute.
Answer:
decomposition
Explanation:
the reactants turn into two different products, thus the reaction is decomposition.
AB -> A + B
Answer:
- 6.38x10²² molecules C₆H₁₂O₆
Explanation:
First we <u>convert the given masses into moles</u>, using the <em>compounds' respective molar mass</em>:
- 64.7 g N₂ ÷ 28 g/mol = 2.31 mol N₂
- 83 g CCl₄ ÷ 153.82 g/mol = 0.540 mol CCl₄
- 19 g C₆H₁₂O₆ ÷ 180 g/mol = 0.106 mol C₆H₁₂O₆
Then we multiply each amount by <em>Avogadro's number</em>, to <u>calculate the number of molecules</u>:
- 2.31 mol N₂ * 6.023x10²³ molecules/mol = 1.39x10²⁴ molecules
- 0.540 mol CCl₄ * 6.023x10²³ molecules/mol = 3.25x10²³ molecules
- 0.106 mol C₆H₁₂O₆ * 6.023x10²³ molecules/mol = 6.38x10²² molecules
