Answer:
The answer to your question is below
Explanation:
Data
Aqueous acetic acid
Aqueous barium hydroxide
Formula
Acetic acid CH₃CH₂COOH
Barium hydroxide Ba(OH)₂
Neutralization reaction
CH₃CH₂COOH + Ba(OH)₂ ⇒ Ba( CH₃CH₂COO)₂ + H₂O
Barium acetate + H₂O
Barium acetate = Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
Oxygen, should be correct
sometimes we use and need mandatory
The answer is A are dense and difficult to compress
The majority of metals are found in ores.
But a few such as copper, gold, platinum, and silver frequently occur in the free state because they do not readily react with other elements.
