Compare the trends for atomic size and first ionization energy.
bazaltina [42]

Explanation:

On a periodic table, the atomic size is depicted by the radius of the atom.

Across a period, the atomic radius reduces progressively from left to right.

Down the group from top to bottom, atomic radii increases progressively.

For the ionization energy, from left to right, across the period, it increases progressively and down a group it reduces.

These two trends are related in that as the atomic radius decreases across the period there is an increasing nuclear charge which is not compensated for by the the successive shells of electrons being added. This also similar down the group.

Determine the balanced chemical equation for this reaction.C8H18(g) O2(g)→CO2(g) H2O(g)Enter the coefficients for each compound
sashaice [31]

Answer:

2C₈H₁₈(g) + 25O₂(g)→16CO₂(g) + 18H₂O

Explanation:

To balance an equation, the moles of one element on one side of the equation should be the same as those on the other side of the equation. This is because (as a law of thermodynamics), in a chemical reaction, the matter is not destroyed nor created - atoms are only rearranged.
