Answer:
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Explanation:
Step 1: Data given
Number of atoms of Fe = 1.17 * 10^22 atoms
Number of Avogadro = 6.022 *10^23
Step 2: Calculate number of moles Fe
Moles Fe = atoms Fe / number of Avogadro
Moles Fe = 1.17*10^22 atoms / 6.022*10^23 / moles
Moles Fe = 0.0194 moles
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Yes Because he really needs it. The amount of sulfur would be
The chart is attached below and the options are as follow,
A Benzene
B Methanol
C Hexane
D Octane
Answer: Option-B (Methanol) is the correct answer.
Explanation: As we know that the substance given to student is soluble in water. Therefore, those substances which are soluble in water are
polar in nature because water is
polar in nature and
Like Dissolves Like.
Hence, in chart it can easily be seen that
Methanol is also polar in nature due to presence of -O-H (polar) bond. So, the substance will dissolve in it.
Answer:
5.85 moles of carbon dioxide are created.
Explanation:
The balanced reaction is:
CaCO₃ → CaO + CO₂
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- CaCO₃: 1 mole
- CaO: 1 mole
- CO₂: 1 mole
Then you can apply the following rule of three: if by stoichiometry 1 mole of CaCO₃ produces 1 mole of CO₂, 5.85 moles of CaCO₃ will produce how many moles of CO₂?

moles of CO₂= 5.85
<u><em>5.85 moles of carbon dioxide are created.</em></u>
The answer is Latitude (B)
