Which laboratory equipment is correctly paired with the unit it measures?

Answers

Answer 1

Answer:

Cilindros graduados

Explanation:

Son una herramienta de medición primaria para el volumen de un líquido, y tiene varias marcas hacia arriba y hacia abajo a lo largo del contenedor con incrementos específicos. Los cilindros graduados vienen en muchos tamaños; entre más pequeños sean de diámetro, más específicas serán las mediciones de volumen. Al leer el volumen de un cilindro graduado, notarán que el líquido parece tener una muesca; el líquido alrededor de los bordes será más alto que el líquido en el centro, inclinándose hacia abajo como los lados de un trampolín cuando alguien está parado en el medio. Esto se llama el menisco. Alineen el punto más bajo del menisco con la marca más cercana, manteniendo el nivel del cilindro para leer correctamente el volumen.

Answers

Answer:

Explanation:

The reaction expression is given as:

           ⁴⁰₁₈ Ar   →   X  +  ⁰₁B  

To solve this problem, we must bear in mind that both mass number and atomic number must be conserved.

 So;

For the mass number:

               40  = A + 0

                 A  = 40

For atomic number:

                 18  = Z + 1

                  Z = 18 - 1  = 17

An atom is identifiable by the atomic number. Since the atomic number of X is 17 then it is Cl, chlorine

The compound F2O has two lone pairs on the central oxygen atom. What's the structure of an F2O molecule? Is this compound polar or non-polar? Question 1 options: A) Bent or angular, polar B) Trigonal planar, polar C) Bent or angular, non-polar D) Trigonal planar, non-polar

Answers

Answer:  A) Bent or angular, polar

Explanation:

The central atom oxygen has two lone pairs and two bond pairs in [tex]OF_2[/tex]. The number of electron pairs are 4,  that means the hybridization will be [tex]sp^3[/tex] and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.

The compound [tex]OF_2[/tex] is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.

How does the number of tin atoms in the sample compare to the number of aluminum atoms in a 20 gram sample of each (Sn:Al)

Answers

The number of Al atoms is greater than the number of Sn atoms

Further explanation

Given

20 gram sample of Tin and Aluminum

Required

Number of atoms

Solution

1 mol = 6.02 x 10²³ particles (atoms, molecules, ions)

So the number of atoms of each element is determined by the number of moles. The greater the number of moles the greater the number of atoms

moles Sn-Tin(Ar = 118,71 u)

mol = mass : Ar

mol = 20 : 118,71 u

mol = 0.168

moles of Al-Aluminum(Ar=26.9815 u)

mol = 20 : 26.9815 u

mol = 0.741

So the number of Al atoms > number of Sn atoms

Why do molecules with dipole-dipole force have higher melting and boiling points than molecules
that only exhibit London Dispersion force?

Answers

Answer:

Because dipole - dipole force is stronger than london dispersion force

Explanation:

Intermolecular forces determines a wide range of physical properties of matter of which melting point is one of them.

Both london dispersion forces and dipole- dipole forces are vanderwaals force.

In london dispersion forces the dipole is temporary

3 reasons why aluminium is used in making of cooking vessels

Answers

Answer is : It is a good thermal and electrical conductor. -The main point to be noted is that aluminium is a highly reactive element and still it is used for making cooking utensils. The reason is that aluminium has a very high affinity for oxygen. So, it reacts with oxygen and forms a layer of aluminium oxide on its surface.

Answer:

This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide . This oxide layer is very stable and prevents further reaction of aluminium with oxygen . Also , it is light in weight and a good conductor of heat Hence , it is used to make cooking utensils .

The compound MnO2 could either have a +4 or a +2 oxidation state on the manganese (Mn) atom. Explain how either scenario could occur.

Answers

Answer:

See explanation

Explanation:

Manganese is a transition element. All transition elements have incompletely filled d orbitals which ultimately makes them to exhibit a variable oxidation state.

Manganese has electronic configuration of [Ar]4s23d5. This means that two electrons could be lost from the s orbital to yield Mn^2+. Also, two electrons could be lost from both s and d orbitals to yield Mn^4+

Calculate the Molar Mass in g/mol of Ammonium Sulfate, (NH4)2(SO4)

Answers

Answer:

132g/mol

Explanation:

The problem here is to find the molar mass of the compound in g/mol

To solve this problem, we simply sum the atomic masses of the atoms in the compound:

   (NH₄)₂ SO₄:

  Atomic mass of N  = 14g

   Atomic mass of H  = 1g

  Atomic mass of S  = 32g

  Atomic mass of O = 16g

So;

   Molar mass = 2[(14 + 4(1))] + 32 + 4(16)  = 132g/mol
