Answer:

4x^3

Explanation:

Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.

Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.

For AB2(s)< -------> A(aq) + 2B(aq). But solubility of AB2= x

Ksp= x × (2x)^2

Ksp= 4x^3

What were the defects in Ruther Ford Atomic model?

juin [17]

the RutherFord atomic model has the limitations in explaining the stability of the atom and the stability of the electron.

<u>Explanation:</u>

As we know basically the atom comprises of the positively charged proton and negative charge electron and no charge neutron.
In these particles, electron revolves with the nucleus as a centre in the orbit with the different energy levels.
So by this revolving action, there will be the loss of energy and thus electrons are to be falling into the nucleus which affects the stability of the electron.
The atom is said to be neutral electrically if the protons and electrons are equal. So in the above case if the electrons on losing the energy if it fells into the nucleus, as a result, the stability of the atom is affected which makes the atom as ions.

Question 10 of 23

Margarita [4]

Answer: O D. A digital signal moves between a discrete number of values.

Explanation:

The digital signals are considered more reliable over the analog signals as they encode the information in a coded form. The bits or samples of the data are transmitted and converted into digital and numerical value. The stream of encoded data is in the form of continuous data at regular time intervals. It provides information in waveform and the data is in compact form. The data is in the form of binary bits 0 and 1 so greater the number of bits greater will be the greater will be the resolution of the information.

Given: CaC2 + N2 → CaCN2 + C In this chemical reaction, how many grams of N2 must be consumed to produce 265 grams of CaCN2? Exp

weeeeeb [17]

Answer : The grams of $N_2$ consumed is, 89.6 grams.

Solution : Given,

Mass of $CaCN_2$ = 265 g

Molar mass of $CaCN_2$ = 80 g/mole

Molar mass of $N_2$ = 28 g/mole

First we have to calculate the moles of $CaCN_2$ .

$\text{Moles of }CaCN_2=\frac{\text{Mass of }CaCN_2}{\text{Molar mass of }CaCN_2}=\frac{265g}{80g/mole}=3.2moles$

The given balanced reaction is,

$CaC_2+N_2\rightarrow CaCN_2+C$

from the reaction, we conclude that

As, 1 mole of $CaCN_2$ produces from 1 mole of $N_2$

So, 3.2 moles of $CaCN_2$ produces from 3.2 moles of $N_2$

Now we have to calculate the mass of $N_2$

$\text{Mass of }N_2=\text{Moles of }N_2\times \text{Molar mass of }N_2$

$\text{Mass of }N_2=(3.2moles)\times (28g/mole)=89.6g$

Therefore, the grams of $N_2$ consumed is, 89.6 grams.

A compound with a molar mass of 100.0 g/lol has an elemental composition of 24.0% C, 3.0% H, 16.0% O and 57.0%F. What is the mol

ch4aika [34]

If I made no mistake in calculation, the given answer must be correct...(tried my best)

elements   :                       carbon     hydrogen    oxygen       Fluorine

composition [C]                     24           3                16                57

M r                                          12             1                16                19

(divide C by Mr)                       2               3                 1                  3

(Divide by smallest value)       2                3                  1                  3

(smallest value = 1...so all value remained constant)

Empirical formula : C2H3OF3

if molar mas = 100 g per mole, then

first step calculate Mr. of empirical formula: [= 100]

Them molecular formula = empirical formula
