Answer:

Option C) Na2SO4 and Na2HAsO4

Explanation:

The solubility of salts can be affected by many things (pH, temperature, etc), this is why when comparing the solubility of two or more salts it's important to establish the conditions.

In this case the graph was made for changes in Temperature, so the first thing is to identify the T=40°C and then, which curves cross at that point.

As can be seen, the <u>red curve</u> (Na2HAsO4) and the <u>blue curve</u> (Na2SO4 ) cross at 40°C indicating that those compounds have similar solubilities at that temperature.

By looking at the graph, you can determine the answer is C. Na2HAsO4 and Na2SO4.

Why does a transformer require AC rather than DC?
LuckyWell [14K]
So if the voltage in case of DC<span> is same as </span>AC<span>, </span>then DC<span> current is larger </span>than AC<span>current. A </span>transformer<span> works on the principle of electromagnetic induction. It means that the change in magnetic flux across a coil induces a potential difference across the same.

Hope this sorta helps! I'm new to this!</span>
