Argon has 8 valence electrons. It's atomic number is 18, therefore, in the first shell there are 2, the second has 8 and the third also has eight.
Answer:
Answer is: A. Vinegar and soda.
Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH) and a base (in this example soda or some other base) react quantitatively with each other.
Balanced chemical reaction of vinegar and soda:
CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).
Sodium acetate (CH₃COONa) is a salt.
The amount of inertia an object has depends on its mass. The more mass an object has, the more inertia. Inertia is an object's tendency to do nothing.
Answer:
CH₄ + 2O₂ –> CO₂ + 2H₂O
The coefficients are: 1, 2, 1, 2
Explanation:
CH₄ + O₂ –> CO₂ + H₂O
The above equation can be balance by as follow:
CH₄ + O₂ –> CO₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:
CH₄ + O₂ –> CO₂ + 2H₂O
There are 2 atoms of O on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before O₂ as shown below:
CH₄ + 2O₂ –> CO₂ + 2H₂O
Now, the equation is balanced.
The coefficients are: 1, 2, 1, 2
Answer:
Fluorine
Explanation:
Fluorine is the most electronegative element because it has 5 electrons in it's 2P shell.
