Answer : The balanced chemical equation is,
Explanation :
Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on product side.
The given unbalanced chemical reaction is,
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of individual elements are not balanced.
In order to balanced the chemical reaction, the coefficient 2 is put before the 
, the coefficient 3 is put before the 
and the coefficient 4 is put before the 
.
The energy evolved in this reaction = 
Thus, the balanced chemical reaction will be,
Stable isotopes are not radioactive nor dangerous.
Unstable isostopes are radioactive and have different mass of the element.
Answer:
Because they have strong roots, they remain stuck in the ground.
Explanation:Because they have strong roots, they remain stuck in the ground.
The nervous system sends signals to the muscles to shiver when our body temperature begins to drop to a lower than normal temperature. the slight movement of the muscles will work to bring temperature back to homeostasis
