Answer : The correct option is, Molecules are speeding up as boiling occurs.

Explanation :

There are three states of matter which are solid, liquid and gas.

In the given diagram,

Arrow 1 shows the boiling process in which the phase changes from the liquid state to gaseous state at constant temperature.

Arrow 2 shows the melting process in which the phase changes from the solid state to liquid state at constant temperature.

Arrow 3 shows the sublimation process in which the phase changes from the solid state to gaseous state at constant temperature.

Arrow 4 shows the condensation process in which the phase changes from the gaseous state to liquid state at constant temperature.

Arrow 5 shows the freezing process in which the phase changes from the liquid state to solid state at constant temperature.

Arrow 6 shows the deposition process in which the phase changes from the gaseous state to solid state at constant temperature.

Hence, the arrow 1 represents the molecules are speeding up as boiling occurs.

In the reaction, 3Cu + 2Al3+ → 3Cu2+ + 2Al, which substance is being oxidized?
Wittaler [7]
In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).

In the experiment "Beer-Lambert’s Law and Spectrophotometry", you prepared a calibration plot similar to the one pictured below.
dexar [7]

Answer:

0.025M

Explanation:

As you must see in your graph, each concentration of the experiment has an absorbance. Following the Beer-Lambert's law that states "The absorbance of a solution is directely proportional to its concentration".

At 0.35 of absorbance, the plot has a concentration of:

<h3>0.025M</h3>
