Answer:
What's the point in all of the 11111?
Answer:
5.79 × 10^23 Oxygen atoms
Explanation:
Number of Oxygen atom in the compound = 4×3 = 12
Molar mass of Al2(SO4)3 = 342 g/mol.
No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole
2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen
= 5.79×10^23 Oxygen atoms
Answer:
C
Explanation:
Introspection is the examination of one's own conscious thoughts and feelings.
Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation.
Each column is called a group<span>. The elements in each </span>group have<span> the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.</span>
It begins with carbon moving from land to the atmosphere. Through combustion, carbon turns to gaseous carbon dioxide. When the atmosphere interacts with the hydrosphere, some of the carbon dioxides dissolves in the water as dissolved carbon dioxide. This can also happen through precipitation. Some of the dissolved carbon dioxides can react with water into carbonic acid.
One way is through the burning of fossil fuels. One of the products of the burning of hydrocarbons is carbon dioxide. Another is clearing of forests. Forests are major carbon sinks since trees sequester carbon dioxide from the atmosphere.
