Which beakers in the model contain solid insoluble substances?

Chemistry
1 answer:
ladessa [460]3 years ago
7 0
Although the models are not provided, I was able to find them and the beakers with solid present in them are:
1C
2A
2C
3A
3C

This is determined by the fact that the beakers all have a piece of closely packed substance laying at the bottom. This closely packed lattice is characteristic of solid substances, and the fact that they exist in the solution in the solid states indicates that they are insoluble.

What are the 4 factors that affect the dissolving of a gas
lara [203]
Nature of the solute and solvent - The amount of solute that dissolves depends on what type of solute it is.  While only 1 gram of lead (II) chloride can be dissolved in 100 grams of water at room temperature, 200 grams of zinc chloride can be dissolved. This means that a greater amount of zinc chloride can be dissolved in the same amount of water than lead II chloride.
Temperature - Increasing the temperature not only increases the amount of solute that will dissolve but also increases the rate at which the solute will dissolve. For gases, the reverse is true. An increase in temperature decreases both solubility and rate of solution.

Pressure - Changes in pressure have practically no effect on solubility. For gaseous solutes, an increase in pressure increases solubility and a decrease in pressure decreases solubility.  Example:  When the cap on a bottle of soda pop is removed, pressure is released, and the gaseous solute bubbles out of solution. This escape of a gas from solution is called effervescence.

Stirring - Stirring brings fresh portions of the solvent in contact with the solute.  Stirring, therefore, allows the solute to dissolve faster.

Hope this helps!! (If not I'm sorry!)

Strontium metal reacts with aluminum chlorate to produce strontium
Fudgin [204]

Answer: single replacement reaction, 3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

A general single displacement reaction can be represented as :

XY+Z\rightarrow XZ+Y

As strontium metal is added to aluminum chlorate , strontium being more reactive than aluminium, displaces aluminium atom its salt solution and lead to formation of strontium  chlorate and aluminum metal.

3Sr+2Al(ClO_3)_3\rightarrow 3Sr(ClO_3)_2+2Al
