Answer:
Hydrometers
Density can be measured using a variety of instruments. A hydrometer is used to determine the density
Explanation:
M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
Answer:
34g of potassium chlorate.
Explanation:
A saturated solution is a solution that, under a temperature, has the maximum amount of solute possible. The maximum amount that a solvent can dissolve of a solute is called <em>solubility.</em>
<em> </em>
The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.
That means, to saturate 100g of water at 70°C you need yo add:
<h3>34g of potassium chlorate.</h3>
Answer:
1 and 2 only
Explanation: These will make a bad impact on water.
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
