How does temperature, pressure and surface area affect the dissolving process

2 answers:

If I am correct, yes. As I was told in chemistry, the surface area affects the dissolving of the "sugar". If you put regular Surat in a hot cup of coffee, it will dissolve at a quick pace, but what if you put the same amount of sugar in the same amour of coffee, but the sugar was fine powder? It would dissolve even faster since it has more surface area. So temperature does affect the dissolving. Hope this helps!

Temperature : - DIssolving process is fastened by increase in temperture.( directly proportional)

Pressure : - Dissolving process is fastened by decrease in pressure.( inversely proportional)

Surface area - Dissolving process is fastened by increase in surface area. ( directly proportional)

How many moles of C3H8 will be produced from 75 moles of CO2?C3H8 + 5 O2 → 3 CO2 + 4 H2O

levacccp [35]

25 moles of C3H8 will be produced from 75 moles of CO2.

<h3>Mole calculation</h3>

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

$C_3H_8 + 5 O_2 = > 3 CO_2 + 4 H_2O$

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:

C3H8 CO2

$\frac{1mol}{xmol} =\frac{3mol}{75mol}$

$x = 25mol$

So, 25 moles of C3H8 will be produced from 75 moles of CO2.

How much sodium chloride is produced from the synthesis of 100g of sodium and an excess of chlorine gas? 2Na + Cl2= 2NaCl

grigory [225]

Answer:

254.35 g of NaCl.

Explanation:

We'll begin by writing the balanced equation for the reaction between sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl). This is illustrated below:

2Na + Cl₂ —> 2NaCl

Next, we shall determine the mass of Na that reacted and the mass of NaCl produced from the balanced equation. This can be obtained as follow:

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 d

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g

SUMMARY:

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Finally, we shall determine the mass of NaCl produced by the reaction of 100 g of Na. This can be obtained as follow:

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Therefore, 100 g of Na will react to produce = (100 × 117)/46 = 254.35 g of NaCl.

Thus, 254.35 g of NaCl were obtained from the reaction.
