Which element has 5 protons 5 neutrons and 5 electrons

Answers

Answer 1
Question: which element has 5 protons 5 neutrons and 5 elections






Answer: Boron
Answer 2

Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.

What are subatomic particles?

Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.

The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.

Therefore, the element is boron.

1. Calculate the number of moles in each of the following masses:
a. 64.1 g of aluminum ans: 2.38 mol Al show work

Answers

Answer:

2.38 mol of Al

Explanation:

To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:

[tex]\frac{64.1 g}{1}[/tex] * [tex]\frac{1 mol}{26.98 g}[/tex]

The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.

Why do some transition metals have multiple oxidation states?

Transition metals have multiple oxidation states because of their (a. completely filled b. partially filled c. empty) (s, p, d, or f) sublevel.

Answers

Answer:

because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation

Explaination:

the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.  

Hope this helped you

Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

What are transition metals?

Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.

It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.

Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.

Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.

Oxidation state is defined as the total number of electrons that have been deleted or added to an element.

It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.

Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

It's how many atoms are in two water molecules (H2O)?

Answers

Answer:

The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O). Here comes the key part. From the Periodic Table of Elements, one sees that one mole of hydrogen atoms weighs 1 gram while one mole of oxygen atoms weighs 16 grams.

Explanation:

:)

The number of atoms present in two water molecules is 6 atoms. 4 hydrogen atoms and 2 oxygen atoms.

What are atoms?

Atoms are the basic unit of a substance. An atom is made of a nucleus, protons, neutrons and electrons. Different atoms combines to form a molecule and molecules combines to form compounds.

Water has the formulas H₂O, thus one molecule of water contains 2 hydrogen and one oxygen. Therefore, two molecules of water that is (H₂O)₂ have 4 hydrogen and 2 oxygens thus, a total of 6 atoms.

Hence, the number of atoms present in two molecules of water is 6.

Crystallization is a separation technique used to separate solute solids from a liquid solvent.

What is Crystallization?

Crystallization is the process of disuniting or separating two substances or molecules that are mixed, and are of different forms of matter. Such as solid and liquid. The process separates mixtures by three processes. These processes are freezing, precipitation, and deposition.

It is the main process of separating solid from liquid. In this process, the solute came above the liquid in crystal form and this is called precipitation.  

Freezing separates the substance that has a different freezing point.  By deposition, the substance that is solid and called solute is deposited below the liquid in the container.    

                                                                                                                                 

Thus, crystallization separates the solute solids from a liquid solvent.

what would you expect to see if a piece of copper metal is placed in a solution that contains nickel(II) ions?
A. copper atoms become copper(II) ions
b. nickel ions become solid nickel
c. no reaction happens
d. a precipitate forms that contains copper and nickel ions​

Answers

Answer:

c. no reaction happens

Explanation:

Let me take your mind back to the idea of electrode potentials of metals. Remember that the more negative the electrode potential of a metal, the more reducing the metal is. Metals with more negative electrode potentials displace metals with less negative electrode potentials from their aqueous solutions.

The electrode potential of nickel is -0.25 V while that of copper is +0.34 V. Hence, copper is lower than nickel in the activity series and can not displace it from aqueous solution.

This implies that, if a piece of copper metal is placed in a solution that contains nickel(II) ions, no reaction happens .

Calculate the volume in of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

Answers

Answer:

380 mL

Explanation:

A chemist must prepare 925 mL of 325 mM aqueous copper(II) sulfate working solution. He'll do this by pouring out some 0.792 M aqueous copper(II) sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

Step 1: Given data

Initial concentration (C₁): 0.792 MInitial volume (V₁): ?Final concentration (C₂): 325 mMFinal volume (V₂): 925 mL

Step 2: Convert "C₂" to M

We will use the conversion factor 1 M = 1000 mM.

325 mM × (1 M/1000 mM) = 0.325 M

Step 3: Calculate the inital volume

We will use the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂/C₁

V₁ = 0.325 M × 925 mL/0.792 M

V₁ = 380 mL

Answers

Answer:

warm, dry downslope wind affecting Southern California - Santa Ana wind

a seasonally changing wind- monsoon

wind blowing from a valley up a mountain slope - valley breeze

Explanation:

The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.

Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.

Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.

Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.
