<em><u>The Rutherford model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.</u></em>
The correct answer is B. Low chemical reactivity
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,
Answer:
a
Explanation:
Because of their valence electron
Carbon, Silicon and germanium has 4 as their valence electron
