White gold is used in jewelry and contains two elements, gold and palladium. A jeweler has two different samples that are both identical in appearance and have a uniform composition throughout. What can be said about the samples?​

Answers

Answer 1
Solution : As they have uniform composition throughout they are considered as homogeneous mixture. Both samples are mixture of two metals (gold and palladium) thus are alloys.
Answer 2
ANSWER

A jeweler has two different samples that are both identical in appearance and have a uniform composition throughout. (1) Since it is given that the white gold is having a uniform composition throughout.So,it means this is a Homogeneous mixtures.

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

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

Chemistry 1 - Types of Radioactive Decay

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

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+

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.
