Answer:
2NaCl > Cl2 + 2Na
Explanation:
2 moles of sodium chloride is irreversible to chlorine gas plus 2 moles of solid sodium
Work as the rest are forms of electricity
Answer:
When the kinetic energy of water vapor decreases during condensation, <u>slowly moving particles near the cool surface condense.</u>
Explanation:
The change of state from a gas to a liquid is condensation. Liquid molecules which have this certain kinetic energy threshold escape from the surface and become vapor. As a result, the remaining liquid molecules now have lower kinetic energy. The temperature of the remaining liquid decreases as evaporation occurs.
The air that surrounded it cooled the cold can or glass. When you're cooling off .They lose kinetic energy, a gas. The particles move more slowly as they move, the attractions between them cause the formation of droplets of liquid. Condensed With, when hot air containing water vapor reaches water, water also forms. Cold surface touch, such as a glass of ice or soil that has a cold surface refrigerated throughout the night.

<span>that's for B, because it says "Iron Sulfate".
which is this equation:
FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
</span>
<span>FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
ratio of FeSO4:NaOH is 1:2,
so you need to moles of NaOH for every mole of FeSO4.

<span>A1-A6 had precipitate, though less ppt every time.
This corresponds to the decrease in the number of NaOH drops
At A2 10/1:40/2 the stoichiometric ratio is equal, so you should've seen the post ppt present. But looking at the picture it doesn't look right. I think you might've labelled them wrong, or there is an error somewhere. This fits micro-plate A better.</span><span>
