Answer is: sodium (Na) and iodine (I₂).
<span>
First ionic bonds in this salt are separeted
because of heat:
</span>NaI(l) → Na⁺(l) + I⁻(l).
Reaction of reduction
at cathode(-): Na⁺(l) + e⁻ → Na(l) /×2.
2Na⁺(l) + 2e⁻ → 2Na(l).
Reaction of oxidation
at anode(+): 2I⁻(l) → I₂(l) + 2e⁻.
The anode is positive
and the cathode is negative.
Answer: For 1 mole of a single atom it is equal to its molar mass. And a single atom, 1 mole is equal to the Avogadro's Number.
Explanation: The relationship can be expressed through the following:
1 mole = molar mass of an atom/ compound
1 atom x 1 mole / 6.022x10^23 atoms
if there is no carbon dioxide your test tube will be blue
if there is a medium amount of carbon dioxide your test tube is green
if there are high amounts of CO2 it will be
yellow
Answer:
vacuoles
Explanation:
Vacuoles are not only found in animal and plant cells, but on every given diagram vacuoles are huge and singular on a plant cell. Animals however, there are multiple and are much smaller
