Covalent solutes are considered non-electrolytes. What does this mean for the conductivity of the solution?

GuDViN [60]3 years ago

Non electrolytes do not dissociate at all in solution and thus they do not produce ions and hence non electrolytes solutions do not conduct electricity. They are typically polar covalent substances that dissolve in water as molecules instead of ions. An example of a non electrolyte is sugar which dissolves in water but does not form ions.

Answer:

This means that this type of solution would not be able to conduct electricity.

Explanation:

Solutions made of electrolytes are able to conduct electricity because they are made from ionic compounds. On the other hand, covalent solutes don't form ions and therefore are not able to conduct electrical charges.

What mass of fes is formed if 9.42 g of fe reacts with 68.0 g of s8? 8fe(s) + s8(s) → 8fes(s)?
allochka39001 [22]
From the equation, we see that the molar ratio of Fe : S required is:

8 : 1

The moles of Fe present are: 9.42/56 = 0.168
Moles of S = 68/(32 * 8) = 0.265

The molar ratio is:

1 : 1.6

Therefore, iron is the limiting reactant as it is present in a ratio lower than that required. The ratio of

Fe : FeS  is
1 : 1

So 0.168 moles of FeS will form. The mass of FeS will be:

Mass = 0.168 * (56 + 32)
Mass = 14.78 grams

14.78 grams of FeS will be formed.

What is AgNO3 + KCI-KNO3+AgCI. What type of reaction does this represent
PIT_PIT [208]
<span>C4H10 + 6.5 O2 ----> 4CO2 + 5H2O 

2C4H10 + 13 O2 ----> 8CO2 + 10H2O 

1. Count the C on the left (4), put a 4 where the C on the right. 

2. Count the H on the left (1), you have two on the right, so you multimply this two by 5. Put the 5 in front of the H2O 

3. Count the O on the right. You have 4*2 + 5 = 13. You have two on the left, so you need 6.5 on the left. 

4. Now multiply everything on the equation by two so you have nice integer numbers. 

5. check you have the same amount of everything on each side. 
Example C: left 8, right 8, etc.
I hope this helps. :)</span><span>

Name the reactants and products of Na3PO4 + 3KOHàNaOH + K3PO4 <br> (Question 2 and 3)
Leona [35]

Answer:

Question 2: Na3PO4, KOH; Question 3: Na3PO4, KOH

Explanation:

Question 2

The reactants in a chemical equation are the species on the left side of the reaction arrow.

Thus the reactants are Na3PO4, KOH (sodium phosphate and potassium hydroxide).

Question 3.

The products in a chemical equation are the species on the right side of the reaction arrow.

Thus the products are NaOH, K3PO4 (sodium hydroxide and potassium phosphate).

Svetllana [295]

Answer:

Number of moles = 10.6 mol

Explanation:

Given data:

Molar mass of H = 1.008 g/mol

Molar mass of C = 12.01 g/mol

Molar mass of O = 16.00 g/mol

Mass of citric acid = 2.03 kg (2.03×1000 = 2030 g)

Number of moles of citric acid = ?

Solution:

Formula:

Number of moles = mass/molar mass

Now we will calculate the molar mass of citric acid:

C₆H₈O₇ = (12.01× 6) + (1.008×8) + (16.00×7)

C₆H₈O₇ = 72.06 + 8.064+112

C₆H₈O₇ = 192.124g/mol

Number of moles = 2030 g/ 192.124g/mol

Number of moles = 10.6 mol
