The sum of all coefficients = 7
<h3>Further explanation</h3>
Given
The word equation
Required
The sum of all coefficients
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Convert the word equation into a chemical equation(skeleton) :
Ga + Cl₂ → GaCl₃
Balanced equation
2Ga + 3Cl₂ → 2GaCl₃
The sum of all coefficients :
= 2+3+2
= 7
Answer: Option (C) is the correct answer.
Explanation:
A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.
Basically in a neutral atom electrons are present in their parent shell.
For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is
.
Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.
Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
D, Urine.
Just google what sweat is made of and it gives you all of the answers except for urine. Also you’d probably smell really bad if your sweat had urine in it. Hope this helps! :)
