Measuring cylinders are more particularly made than beakers for accurate measurements of liquids with a significantly lower error.

They have many more graduation markings and close to 0.5-1% inaccuracy, allowing them to precisely measure liquids ranging from 1ml to 1L.

Because of the permanently defined incremental graduations included in the transparent cylinder, a graduated cylinder is regarded more accurate than a beaker for measuring volume.

Because the volume markers on a beaker are simply approximations, they only offer whole numbers. For example, if a 100 mL beaker only has markers every 20 mL, determining the precise volume of a liquid sample lying between the 60 mL and 80 mL marks would be difficult.

Mendeleev’s periodic table is an arrangement of elements in an increasing atomic mass order in a tabular form.

The elements are arranged in Mendeleev's periodic table in a tabular format, increasing atomic mass order to represent similarities and patterns in the behavior of the elements.

In the beginning, Mendeleev organized the elements in ascending order of atomic weight. Nearby elements with related characteristics are positioned. In the same horizontal row, elements are located that have comparable characteristics.

The gaps that Mendeleev left in his table were one of its distinctive features. He not only anticipated the existence of yet-undiscovered elements within those locations, but also their atomic weights and other properties.

Mendeleev's periodic table organizes the elements according to their atomic mass, meanwhile the Modern Periodic Table does it according to their atomic number. This is the fundamental distinction between the two periodic tables.

The concentration of [Ba²⁺] when SrCrO₄ begins to precipitate in the reaction is 3.4×10⁻⁷

It is given that the solution of Ba(NO₃)₂ and Sr(NO₃)₂ has a molar concentration of 0.10M, then the concentration of SrCrO₄ can be written as follows

Ksp(SrCrO4)= [Sr²⁺][CrO₄²⁻]

[CrO₄²⁻] = 3.5×10⁻⁵/0.1

              =3.5×10⁻⁴

From this we can say that the concentration of CrO₄²⁻ is 3.5x10⁻⁴, then the concentration of Ba²⁺ in BaCrO₄ can be computed as follows:

Ksp(BaCrO₄) = [Sr²⁺][CrO₄²⁻]

This is because at equlibrium the concentration of Ba²⁺ will be same as that of Sr²⁺. Then,

[CrO₄²⁻]Total =[CrO₄²⁻] from SrCrO₄

[Ba²⁺] = 1.2×10⁻¹⁰/3.5×10⁻⁴

[Ba²⁺] = 3.4×10⁻⁷

Cl = 34.85 mg

Convert mg to moles

                                 31 mg of P ----------------- 1 mmol

                                 10.15 mg  ------------------   x

The boiling point of butanol (CH3CH2CH2CH2OH) is predicted to be  

> 97°C and < 137°C

Because propanol is bigger and has more London Dispersion Forces, the intermolecular forces are stronger and it takes more energy to separate the molecules. Propanol also has higher mass, thus moving it around and separating it also demands more energy. Both of these will result in propanol having a higher boiling point.

The boiling point of an alcohol is always significantly higher than that of the analogous alkane. Pentanol has higher mass and more London dispersion forces than butanol. These two factors determine the boiling point of alkane. Thus, butanol demands less energy than pentanol to separate the molecules.

The relative stability of radicals dictates their respective reactivity because the alkyl radical is a crucial intermediate in the halogenation process of alkanes. The more reactive alkane is the one that produces the more stable carbon radical.

Different alkyl radical structures exhibit various stabilities. The stability of radicals follows the same pattern as that of carbocations, with tertiary radicals being the most stable and primary and methyl radicals being the least stable.
