it makes aloh
AlCl3 + 3NaOH = AlOH3 + 3NaCl
Al3+ + 3Cl- + 3Na+ + 3OH- = AlOH3 + 3Na+ + 3Cl-
all cancels out except
Al3+ + 3OH- = AlOH3
A molecule and its chair flip are related by being labled as Conformational isomers
The process of rotating around single bonds to change one cyclohexane chair conformation into another. Axial substituents become equatorial upon cyclohexane ring flip, whereas equatorial substituents become axial.
<h3>What is Conformational isomers ?</h3>
Stereoisomers created by rotation (twisting) about -bonds are known as conformational isomers (also known as conformers, rotational isomers, or rotamers), and they frequently interconvert quickly at room temperature.
- For instance, butane contains three conformers related to its two methyl (CH3) groups: two gauche conformers with enantiomeric methyls that are spaced 60 degrees apart, and an anti conformer with coplanar four carbon centres and 180-degree-spaced substituents (refer to free energy diagram of butane).

Answer:
Lets the total pressure is Pt and the individual gases are designated as pH2, pCO2, pNe, pO2.
Pt = pCO2+ pNe+pO2+ pH2
285KPa = 13 KPa+ 14 KPa + 157 KPa +pH2
Now add the partial pressure of CO2, Ne and O2 which is equal to 184 KPa.
285 KPa = 184 KPa + pH2
Now subtract the individual pressure of each gas from thje total pressure.
285 KPa - 184 KPa = pH2
101 KPa = pH2
The partial pressure of hydrogen is 101 KPa.
Let us consider each statement one by one
a) Catalysts are the substance which alter the reaction pathway where activation energy of reaction is less that the un catalyzed reaction. They are not used up in the reaction . the catalyst is restored in the reaction.
b) As mentioned above, the catalyst speed up reaction by lowering the activation energy
c) During a reaction the reactants are consumed up and products are formed. so there is a decrease in concentration of reactant.
Thus all the above statements are true.
D) the rate of decrease in concentration of reactants depends upon the coefficient of reactant in balanced chemical reaction.
For example
Here the rate of decrease in concentration of hydrogen will be double the rate of decrease in concentration of oxygen.
Answer:
0.26 mol KNO₂
Explanation:
A buffer is defined as the mixture of a weak acid with its conjugate base or vice versa.
Nitrous acid (HNO₂) is a weak acid with pka of 3.3. Its conjugate base is NO₂⁻. KNO₂ in solution produce K⁺ + NO₂⁻. That means right answer is:
0.26 mol KNO₂.
I hope it helps!
