How many carbon atoms would be in the compound named chlorobenzene

Chemistry
1 answer:
kondaur [170]4 years ago
7 0

chlorobenzene
Carbon - 6
Hydrogen - 5
Chlorine - 1

that 1 chlorine replaces one of the hydrogens
thats why hydrogen number decreases by number of Cl atoms (that are substituting those H atoms)

Nuclear fission differs from nuclear fission because nuclear fusion reactions
velikii [3]
<span>Nuclear reactions have two main types: fission reactions and fusion reactions.  When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number.  In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact).  </span>

What is the pOH of a 0.00037 M solution of barium hydroxide
ruslelena [56]

Answer: pOH = 3.13

Ba(OH)2 is a very basic substance. The general formula for pOH is - log(OH)

Barium Hydroxide produces 2 moles of OH for every mole of Ba(OH)2 present in the solution.


0.00037 M = 3.7 * 10^-4 Ba(OH)2 will produce 2 *0.00037 M of OH-

OH- = 2* 0.00037 = 0.00074

pOH = - log(0.00074) = 3.13

Calculate the enthalpy of the reaction
harkovskaia [24]

Answer : The enthalpy of the reaction is, -2552 kJ/mole

Explanation :

According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.

The given enthalpy of reaction is,

4B(s)+3O_2(g)\rightarrow 2B_2O_3(s)    \Delta H=?

The intermediate balanced chemical reactions are:

(1) B_2O_3(s)+3H_2O(g)\rightarrow 3O_2(g)+B_2H_6(g)     \Delta H_A=+2035kJ

(2) 2B(s)+3H_2(g)\rightarrow B_2H_6(g)    \Delta H_B=+36kJ

(3) H_2(g)+\frac{1}{2}O_2(g)\rightarrow H_2O(l)    \Delta H_C=-285kJ

(4) H_2O(l)\rightarrow H_2O(g)    \Delta H_D=+44kJ

Now we have to revere the reactions 1 and multiple by 2, revere the reactions 3, 4 and multiple by 2 and multiply the reaction 2 by 2 and then adding all the equations, we get :

(when we are reversing the reaction then the sign of the enthalpy change will be change.)

The expression for enthalpy of the reaction will be,

\Delta H=-2\times \Delta H_A+2\times \Delta H_B-6\times \Delta H_C-6\times \Delta H_D

\Delta H=-2(+2035kJ)+2(+36kJ)-6(-285kJ)-6(+44)

\Delta H=-2552kJ

Therefore, the enthalpy of the reaction is, -2552 kJ/mole

Which solvent, water or hexane (C6H14), would you choose to dissolve each of the following?1. NaCl2. HF3. Octane4. (NH4)2SO4
hjlf

Answer:

            Water for;

                            (a) NaCl

                            (b) HF

                            (c) (NH₄)₂SO₄

            Hexane for;

                             (a) Octane

Explanation:

                     In chemistry there is a Rue of Thumb, "<em><u>Like Dissolves Like</u></em>" according to which polar compounds will dissolve in polar solvents and non-polar compounds will dissolve in  non-polar solvents.

In given statement two solvents are given.

             (1) Water: Water is a polar compound. It has a polar bond and a bent shape, hence has a net dipole moment.

             (2) Hexane: Hexane is nonpolar because the electronegativity difference between the carbon atom and hydrogen atom is very less i.e. 0.4.

Therefore, polar solutes like NaCl (ionic), HF (highly polar) and (NH₄)₂SO₄ (ionic compound) will dissolve in water and Octane (C₈H₁₈ nonpolar) will dissolve in hexane respectively.
