The number of oxygen atoms that are in 4 Al₂O₃ are 12 atoms
<u><em> Explanation</em></u>
- The subscript in a chemical formula indicate the number of atoms of element immediately before the subscript.
- coefficient is the number in front of the formula and tells us how many molecules of a given formula are present.
- Since 4Al₂O₃ has coefficient of 4 and the subscript of O is 3 the number of O atoms = 4 x 3=12 atoms
Answer:
B)
Explanation:
Hydrogen boding
Is a primarily electrostatic force of attraction between a hydrogen atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements.
Answer: The correct answer would be : True

Answer:
It will be higher in the summer.
Explanation:
Usually, the winter season is more harsh a weather on leaves than summer because it is wet season and thus has less sunlight and this means there will be less photosynthesis reactions and therefore it means the partial pressure will be lesser here unlike in the summer when it is a more warm and dry weather with sunlight where photosynthesis reactions will be more favorable to occur.
Thus, CO2 which is a great component of photosynthesis is used more in the summer and as such the partial pressure in the summer will be higher.
