K + I - > KI
Potassium (needs to lose 1 electron) responds with Iodine (needs to pick up 1 electron) to fulfill both component's octet, shaping a salt, potassium iodide
This is a similar case for NaCl, simply unique components. Trust this made a difference.
Answer:
One mole
Explanation:
The balanced chemical equation is
<u>1</u>NaOH + <u>1</u>HNO₃ ⟶ NaNO₃ + H₂O
<u>1</u> mol <u>1</u> mol
The coefficients in front of the formulas tell you the amount of something that reacts with an equivalent amount of something else.
In this reaction, 1 mol NaOH reacts with 1 mol HNO₃.
There are several differences between<span> a </span>physical and chemical change<span> in matter or substances. A </span>physical change<span> in a substance doesn't </span>change<span> what the substance is. In a </span>chemical change<span> where there is a </span>chemical<span> reaction, a new substance is formed and energy is either given off or absorbed.</span>
Opposite pairs form ionic bonds, due to this the answer is D - Li and Br; They have unlike charges.
