Let us understand the types of given intermolecular forces

a) dipole-dipole : this is present between two polar molecules having permanent dipole

eXample : dipole dipole interaction between HCl-HCl molecule

b) dipole induced dipole : here a polar molecule having a dipole induces dipole in another non polar molecule due to attraction /repulsion for electrons and attraction / repulsion for nucleus.

c) hydrogen bond : the interaction between a hydrogen atom bonded with a highly electr-onegative element (F,O or N) and another highly electro-negative element (F,O or N)

Example Water-water

d) london dispersion : these are weekest of all the intermcolecular forces and are between the electrons of one molecule / atom and nucleus of another molecules.

The strongest intermolecular forces is hydrogen bond

How many moles are there in 24.00 g of NaCl

Elis [28]

Answer:

The answer to your question is 0.41 moles

Explanation:

Data

moles of NaCl = ?

mass of NaCl = 24 g

Process

To solve this problem just calculate the molar mass of NaCl, and remember that the molar mass of any substance equals to 1 mol.

1.- Calculate the molar mass

NaCl = 23 + 35.5 = 58.5 g

2.- Use proportions and cross multiplication

58.5 g of NaCl ------------------- 1 mol

24.0 g ------------------- x

x = (24 x 1) / 58.5

x = 0.41 moles

Fill in the coefficients that will balance the following reaction:

Alex17521 [72]

Answer:

To balance a reaction, the amount of reactants must be equal to the amount of products, as stated by the Law of Conservation of Matter. It may help you to keep track of the number of each element in a list as you try to balance. It's not able to be balanced.

natali 33 [55]

Answer: Equilibrium constant for this reaction is $2.8 \times 10^{15}$ .

Explanation:

Chemical reaction equation for the formation of nickel cyanide complex is as follows.

$Ni(OH)_{2}(s) + 4CN^{-}(aq) \rightleftharpoons [Ni(CN)_{4}^{2-}](aq) + 2OH^{-}(aq)$

We know that,

K = $K_{f} \times K_{sp}$

We are given that, $K_{f} = 1.0 \times 10^{31}$

and, $K_{sp} = 2.8 \times 10^{-16}$

Hence, we will calculate the value of K as follows.

K = $K_{f} \times K_{sp}$

K = $(1.0 \times 10^{31}) \times (2.8 \times 10^{-16})$

= $2.8 \times 10^{15}$

Thus, we can conclude that equilibrium constant for this reaction is $2.8 \times 10^{15}$ .

Goryan [66]

The process which has taken place is called CRYSTALLIZATION.
Generally, crystallization is the process by which solid crystals are precipitated from solution. Crystallization can also occur when a crystal melt or when a crystal get deposited directly from a gas, although these cases are rarer compare to crystals forming from solutions.
