A hot filtration should be used in the process of Crystallization.

<h3>What is Crystallization?</h3>

This is the conversion of a chemical in liquid form to a crystalline solid. The crystal formed are repeating three-dimensional pattern or lattice.

Hot filtration is used in the process of Crystallization of a solid which contains impurities that are insoluble in the crystallization solvent and also to remove highly colored impurities from a solid.

The mass of a compound is taken 5 times with the following results: 26.6 mg, 26.3 mg, 26.2 mg, 26.4 mg, and 26.1 mg. If
Maru [420]

Answer:

2.813%

Explanation:

First, we must take the average of the five mass measurements

Average value= sum of all five trials/ 5= 26.6 + 26.3 + 26.2 + 26.4 +26.1 /3 = 26.32mg

Now, we have been provided the accurate mass of the compound in the question as 25.6mg

Remember that relative percent error = Average value of measurement - True value of measurement / true value×100

Hence we have;

Percent error=

26.32 - 25.6/25.6 ×100

Percent error= 2.813%

O magnésio possui isótopos com número de massa (A) iguais a 24, 25 e 26. Quantas particulas fundamentais estao presente em cada
NeX [460]

Explanation:

The fundamental particles in an atom are protons, neutrons and electrons. The given atoms are called the isotopes of magnesium. They only differ in the number of neutrons they possess.

Protons are the positively charge particles in an atom

Neutrons occupy the center of an atom with protons and they carry no charges

Electrons orbits an atom and they carry no charges.

For a neutral atom, the number of protons and electrons are the same.

   Magnesium - 24

   Magnesium - 25

   Magnesium - 26

Magnesium is an atom on the periodic table with an atomic number of 12.

The atomic number is the number of protons in an atom.

   The numbers in front of the problem given are the mass numbers.

For neutral atoms;

  Number of protons = number of electrons = atomic number

Number of neutrons = Mass number - atomic number

Magnesium - 24                          

Protons = 12

Electrons = 12

Neutrons = 24 - 12 = 12

Magnesium - 25

Protons = 12

Electrons = 12

Neutrons = 25-12 = 13

Magnesium - 26

Protons = 12

Electrons = 12

Neutrons = 26 - 12 = 14
