Answer:

Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!

Explanation:

Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron.

11111nata11111 [884]

ANSWER

$\begin{gathered} \text{ 2KBr }+\text{ CaO }\rightarrow\text{ K}_2O\text{ }+\text{ CaBr}_2 \\ Option\text{ B} \end{gathered}$

EXPLANATION

Given that;

The two reactants are KBr and CaO

Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.

$\text{ 2KBr + CaO }\rightarrow\text{ K}_2O\text{ + CaBr}_2$

Therefore, the resulting products of the given data are K2O + CaBr2

The correct answer is option B
