Chemist prefer to use kipp’s apparatus for the production of hydrogen sulphide instead of woulf’s bottle because they produce gas without generating heat.

Kipp's appratus and woulf's bottle both are the laborartory appratus and used in the analytical process of any reactions.

Hydrogen sulphide gas will be produced in the laborartory by using both given appratus but we prefer the use of kipp's apparatus because in this apparatus small amount of gas is produced in the controlled heat condition by the reaction between the liquid sulphuric acid and solid iron sulphide.

Hence we prefer kipp's appratus as it produces gas without heat.

Answer:+6

Explanation:Oxygen always has an ON of -2 so when there’s O7 the total is -12. Sodium is in group 1 so has an ON of +1 that means with two of them it’s overall ON is +2. When you combine the two that equals -12 but you want it to equal 0. So it would be +12. Considering there are two chromium present you would divide that by 2 making the answer +6.

Explanation:

For  a typical mammalian cell, the net transport by the sodium-potassium exchange pump, Work done is mathematically given as

W= 5.6*10-18 J

Generally, the equation for the Potential difference   is mathematically given as

Potential difference = Work done / Charge

Therefore

W=q*P.d

Q= 500 * 1.6*10-19 C

P.d. = 70 mV

In conclusion,Workdone  

W500 * 1.6*10-19 * 70*10-3

W= 5.6*10-18 J

Acids or bases with strong bonds remain as molecules in solutions known as weak acids or bases. The acids or bases with weak bonds easily dissociate into ions and are called strong acids or bases.

Acid is proton donor hydrogen containing substance. Base is proton acceptor molecule.

It can be predicted by pH indicator. pH with value less than 7 indicate acidity and value with more than 7 denotes base, and the one with value 7 is considered as neutral.

Thus, based on bond strength and its dissociation in the water makes it strong acid or weak base.

The new volume occupied by the sample of gas is 4.96L.

Given the data in the question;

Final Volume; [tex]V_2 = \ ?[/tex]

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

To calculate the new volume the gas occupy, we subtsitute our given values into the expression above.

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\ \\ P_1V_1T_2 = P_2V_2T_1\\\\0.750atm * 8.20L * 325K = 1.075atm * V_2 * 375K\\\\1998.75LatmK = 403.125atmK * V_2\\\\V_2 = \frac{1998.75LatmK}{403.125atmK} \\\\V_2 = 4.96L[/tex]

Therefore, the new volume occupied by the sample of gas is 4.96L.

Taking into account the reaction stoichiometry, 1.119 grams of chlorine gas are required to produce 3.32 grams of bismuth chloride is produced.

In first place, the balanced reaction is:

2 Bi + 3 Cl₂ → 2 BiCl₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Bi: 2 moles ×209 g/mole=418  g

Cl₂: 3 moles ×70.90 g/mole= 212.7 g

BiCl₃: 2 moles ×315.45 g/mole= 630.9 g

The following rule of three can be applied: If by reaction stoichiometry 630.9 grams of BiCl₃ are formed by 212.7 grams of Cl₂, 3.32 grams of BiCl₃ are formed by how much mass of Cl₂?

[tex]mass of Cl_{2} =\frac{3.32 grams of BiCl_{3}x212.7 grams of Cl_{2} }{630.9 grams of BiCl_{3}}[/tex]

mass of Cl₂= 1.119 grams

Finally, 1.119 grams of chlorine gas are required to produce 3.32 grams of bismuth chloride is produced.

The molecule ammonium lauryl sulfate is a detergent because of its hydrophobic tail and a hydrophilic head which are responsible for its cleansing action.

Though not shown, I presume that the property labelled as C must have to do with the cleasing action of the molecule ammonium lauryl sulfate.

The substance has a hydrophobic tail and a hydrophilic head which enables it to form miscles and these are the responsible for the cleansing action of the ammonium lauryl sulfate molecule.
