Water is deemed as a polar molecule because of the electrostatic attraction occurring between molecules. One major key characteristic of knowing polar molecules is knowing their atomic geometry. Now, we know that water has two hydrogens and one oxygen atom covalently bonded to each other. This means that they share electrons. However, this sharing is unequal because oxygen is more electronegative compared to hydrogen. So, the electrons tend to be nearer to the oxygen atom making it partially negative. On the other hand, the hydrogen would be partially positive. Polarity arises when there is an imbalance in the pull of electrostatic forces between individual atoms. If you look at the molecular geometry of water, its shape is bent. As a result, it creates a dipole moment which attracts solute to bond with water. In chemistry, the primary rule of solubility is that 'like dissolves like'. This means that polar solutes will dissolve in polar solvents. Similarly, nonpolar solutes will dissolve in nonpolar solvents.

what is the molecular formula for a compound with the empirical formula: K2SO4 and a molecular mass of 696g​
LekaFEV [45]

Answer:

K8S4O16 or K8(SO4)4 depending on if the SO4 is supposed to represent sulfate or not

Explanation:

Find the molar mass of K2SO4 first:

2K + S + 4O ≈ 174 g/mol

Divide the goal molar mass of 696 by the molar mass of the empirical formula:

696 / 174 = 4

This means you need to multiply everything in the empirical formula by 4:

K2SO4 --> K8S4O16 or K8(SO4)4 depending on if the SO4 is for sulfate or not

Answer quickly i'm out of time !!!!!!
melamori03 [73]

Answer:

Option D. pH= 1.3 strong acid

Explanation:

From the question given:

The hydrogen ion concentration [H+] = 0.05 M

pH = —Log [H+]

pH = —Log 0.05

pH = 1.3

Since the pH lies between 0 and 7, the solution is acidic. Since the pH value is low, the solution is a strong acid

Please help me with this question
vampirchik [111]

Remember that

  • For being a bond covalent ∆E<1.8
  • For being a bond ionic ∆E>1.8

#1

  • ∆EN=0.5

Carbon is present so it's covalent

#2

  • OH bond is also covalent

#3

  • P-H will hardly form a bond

#4

  • Ionic bond

#5

  • Ionic bond

At the equilibrium point in the decomposition of phosphorus pentachloride to chlorine and phosphorus trichloride, the following
Hitman42 [59]

Answer: K_{eq} for the reaction is 5.55

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

                        PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)          

At eqm. conc.   (0.010) M     (0.15)  M   (0.37) M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[Cl_2]\times [PCl_3]}{[PCl_5]}

Now put all the given values in this expression, we get :

K_c=\frac{(0.37)\times (0.15)}{(0.010)}

K_c=5.55

Thus the K_{eq} for the reaction is 5.55
