Consider the total ionic equation below.
ZanzabumX [31]

Answer:

\boxed{\text{Ba}^{2+}}

Explanation:

\rm 2H^{+} + CrO_{2}^{3-} + \textbf{Ba}^{2+} + 2OH^{-} \longrightarrow \textbf{Ba}^{2+} + CrO_{2}^{4-} + 2H_{2}O

The spectator ions are the ions that are on both sides of the equation.

\text{In this equation, the spectator ions are }\boxed{\textbf{Ba}^{2+}}.

They are present at the beginning and at the end of the reaction. They don't take part in the reaction. They are simply "spectators" watching the other ions "do their thing."

The<span> pros of using GMO are that they result in higher yields than natural food crops hence able to feed a growing human population on earth. They are also able to withstand crop diseases and pests hence improved yields. </span>

The cons of transgenic plants contribute to antibiotic resistance especially due to the use of antibiotic resistance genes in recombination genes. Another is the environmental impact. GMO may result in uncontrolled gene transfer to natural crops in the environment hence created challenges such as super-weeds.
