Answer:
mass and the square of the magnitude of velocity.
Explanation:
The atom with the strongest attraction for electrons in bond formation is the atom with the most positive charge since an electron has a negative charge. Unlike attracts like. Among these, Sr and ba has 2+ and has the greatest charge but ba has a stronger electron affinity (decreasing from top to bottom). answer is barium.
Answer:
Explanation:
Spectator ions are ions in a solution/reaction that do not take part in a chemical reaction (hence are called "spectator" ions). <u>They can be identified when they are found both in the reactant and product sides</u>.
The reaction between lead(II) nitrate, Pb(NO₃)₂ and sodium chloride, NaCl is illustrated below
Pb(NO₃)₂ + 2NaCl ⇒ PbCl₂ + 2NaNO₃
According to solubility rules, all the compounds above (with the exception of PbCl₂) are all soluble and would dissociate when involved in a reaction.
Hence, the ionic equation based on the description above will be
Pb²⁺ + 2NO₃⁻ + 2Na⁺ + 2Cl⁻ ⇒ PbCl₂ + 2Na⁺ + 2NO₃⁻
From the above ionic equation, <u>it can be noted that both 2NO₃⁻ and 2Na⁺ are found on both the reactant and product side and are hence the spectator ions.</u>
