Ionization energy is directly proportional to elements location on the periodic table
Salt is a compound.
Most salts are ionic compounds, meaning that they are made up of ions rather than molecules.
Explanation:
It is the heat required to change a gram of substance from a liquid to a gas.
Answer:
<u>1</u>Al₄C₃ + <u>12</u>H₂O → <u>3</u>CH₄ + <u>4</u>Al(OH)₃
Explanation:
<u>SOLUTION :-</u>
Balance it by using 'hit & trial' method , and you'll get the answer :-
<u>1</u>Al₄C₃ + <u>12</u>H₂O → <u>3</u>CH₄ + <u>4</u>Al(OH)₃
<u>VERIFICATION :-</u>
<em>In reactant side of equation :-</em>
- Number of atoms in Al = 1×4 = 4
- Number of atoms in C = 1×3 = 3
- Number of atoms in H = 12×2 = 24
- Number of atoms in O = 12×1 = 12
<em>In product side of equation :-</em>
- Number of atoms in C = 3×1 = 3
- Number of atoms in H = (3×4) + 4(1×3) = 24
- Number of atoms in Al = 4×1 = 4
- Number of atoms in O = 4(1×3) = 12
Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
Based on the above descriptions provided for silicon, I'm assuming that you want to know what silicon is categorized as, in the periodic table, since it posses some properties of metals and nonmetals it would be classified as a mettaloid or a semi metal.
