There is honestly no right answer for this but here is what I would put:

Atomic mass increases as you go from left to right. If you look at the periodic table, it would be between Sn and Sb. It would bet here because Sn is 118 and Sb is 121. Basing it off of Antimony and putting it in group 15, the properties are that it is metallic and is a poor conductor of heat. I would call it Stin, which would be shortened to St.

Naoh is a strong electrolyte, and ch3oh is a nonelectrolyte. how is the solution of naoh different from that of ch3oh?

Misha Larkins [42]

Answer: NaOH has ionic bonds Na+ and Cl- and in water the ions float free with their charge so that the charged can carry electric current. The other compound has (non-ionic)covalent bonds.

Jaką maksymalną ilość gramów azotanu (V) potasu można rozpuscic w 300g wody w temperaturze 90 C

olga2289 [7]

Answer:

609g

Explanation:

The translated question is:

What maximum amount of grams of potassium nitrate (V) can be dissolved in 300g of water at 90 °C

<h2>Solution</h2>

To answer the question you need to consultate the solubiity information for potassium nitrate (V), KNO₃.

The attached table contains the solutibility table for KNO₃ at different temperatures.

At 90ºC it is 203g / 100g water.

Then, to calculate the maximum amount of grams of potassium nitrate (V) that can be dissolved in 300g of water at 90 °C, just multiply by the amount of water:

203g / 100g water × 300 g water = 609g ← answer
