Answer:
X represents oxygen and Y represents carbon dioxide.
Explanation:
Because in respiration, you consume oxygen and make carbon dioxide whereas, in photosynthesis, the equation is reversed and you use carbon dioxide and make oxygen and glucose.
Answer:The distribution of electrons in an atom is called as Electronic Configuration. Formula 2n2 helps in the determination of the maximum number of electrons present in an orbit, here n= orbit number.
Explanation:
Answer:
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
Answer: The balanced equation is
.
Explanation:
The given reaction equation is as follows.

Number of atoms present on reactant side are as follows.
- Li = 1
- H = 1
= 1
Number of atoms present on product side are as follows.
- Li = 1
- H = 2
= 1
To balance this equation, multiply Li by 2 and
by 2 on reactant side. Also, multiply
by 2 on product side.
Hence, the equation can be rewritten as follows.

Now, number of atoms present on reactant side are as follows.
- Li = 2
- H = 2
= 2
Number of atoms present on product side are as follows.
- Li = 2
- H = 2
= 2
As there are same number of atoms on both reactant and product side. Hence, the equation is now balanced.
Thus, we can conclude that the balanced equation is
.
