In evolutionary biology, a common ancestor is allegedly a link between two varying branches or types of creatures. (Another word for these is 'missing links', since up to this point, not a single one of these common ancestors has been found in the fossil record)
Hope that helped =)
Answer:
52.8 g of O2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
4Al + 3O2 —> 2Al2O3
From the balanced equation above,
4 moles of Al reacted with 3 moles of O2 to produce 2 moles of Al2O3
Next, we shall determine the number of mole of O2 needed to react with 2.2 moles of Al. This can be obtained as follow:
From the balanced equation above,
4 moles of Al reacted with 3 moles of O2.
Therefore, 2.2 moles of Al will react with = (2.2 × 3)/4 = 1.65 moles of O2.
Thus, 1.65 moles of O2 is needed for the reaction.
Finally, we shall determine the mass of O2 needed as shown below:
Mole of O2 = 1.65 moles
Molar mass of O2 = 2 × 16= 32 g/mol
Mass of O2 =?
Mole = mass/Molar mass
1.65 = mass of O2 /32
Cross multiply
Mass of O2 = 1.65 × 32
Mass of O2 = 52.8 g
Therefore, 52.8 g of O2 is needed for the reaction.
you could easily search this on Google but it's 0.004312.
1000000 Cubic Meter is 1 cubic centimeter.
but if there is 4312, do 4312/10000000..
An increase in pressure increasing the billing point is an example of a physical property.
- The term "boiling point" describes the temperature at which a liquid, which is being boiled, changes from a liquid to a vapor when its pressure equals that of its environment.
- Physical changes are those that take place when a material's structure is the same both before and after the change.
- When a substance is changed into another chemical substance, this is known as chemical transformation.
- When describing the state of a physical system, a substance's physical qualities are those that can be measured.
- A substance's characteristic that is seen in a chemical reaction is referred to as a chemical property.
As it demonstrates the physical state, the increase in pressure with boiling point is an example of a physical property.
