if you burn a piece of wood you will feel heat see water vapor and be left with ashes how come the matter was not destroyed

Elanso [62]

The matter wasn't destroyed because albert einsteins theory of the black hole says that matter cannot be destroyed if it is burned into the same color of a black hole. this eqation proves my thesis:

²²↑↑Ф $\left \{ {{y=2} \atop {x=2}} \right. \left \{ {{y=2} \atop {x=2}} \right. \left \{ {{y=2} \atop {x=2}} \right. \left \{ {{y=2} \atop {x=2}} \right.$

What controls the electrical properties of the atom? the valence electron is referred to as a __________ ? when silicon atoms co

Drupady [299]

<span>It is the valence orbit that controls the electrical properties of the atom. The valence electron is referred to as a "free electron.' Valence electrons have the highest energy of all electrons in an atom; they are also the most reactive, meaning they are usually the electrons involved in bonding. When silicon atoms combine to form a solid, they arrange themselves into an orderly pattern called a crystal.</span>

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."
