the number of moles in 4.5 x 10^24 atoms of oxegen is​

Answers

Answer:

The answer is 7.48 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{4.5 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 7.47508...[/tex]

We have the final answer as

7.48 moles

Enter the symbol of the element which would have 36 electrons and -3 charge.

Answers

Answer:

Arsenic if I understood correctly

Explanation:

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore, the element with atomic number 33 and -3 charge is Arsenic.

What is Ions?

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. The element with atomic number 33 and -3 charge is Arsenic.

Therefore, the element with atomic number 33 and -3 charge is Arsenic.

Explanation:

Chloe is training for her first half-marathon, which requires her to run 21.1 km. Before she runs, she carefully chooses the foods that will give her the energy her body requires for the race. She stands still at the starting line, then she starts running, her body warming up as she runs. Which three energy transformations take place in this example? Potential energy to kinetic energy Chemical energy to thermal energy Chemical energy to kinetic energy Mechanical energy to chemical energy

Answers

Answer:

The transformation is of chemical energy (use the ATP molecule as a resource) which is then transformed into mechanical energy (muscle contraction) and finally transformed into thermal energy (increase in body temperature, or sweating)

Explanation:

Energy is never lost, it is always transformed, that is why energy is yielding electronic movement and expressing itself in different ways, first as chemical energy, then as mechanical energy, and lastly as thermal energy.

It is important to clarify that the energy source of all this transformation is food and energy reserves.

substance in a 968 g sample. Which compound most likely represents this
unknown substance?
CO
CIO
2)
CO2
N203
CLEAR ALL

Answers

Answer:

The correct option is;

CO₂

Explanation:

The given information are;

The number of molecules in the substance = 1.3 × 10²⁵

The mass of the substance = 968 g

Therefore, we have;

The number of molecules in one mole of a substance = 6.02 × 10²³

The number of moles present = (1.3 × 10²⁵)/(6.02 × 10²³) ≈ 21.595 moles

Therefore, 968 g = 21.595 moles

1 mole = 968/21.595 = 44.826 g

The mass of one mole of the substance = 44.826 g

Therefore the mass of one mole of the substance is closely related to the mass of one mole of CO₂ which is 44.01 g/mol.  

The correct option is CO₂

The calculation is as follows:

The number of molecules in one mole of a substance should be = 6.02 × 10²³

And,

The number of moles present is

= (1.3 × 10²⁵)/(6.02 × 10²³)

≈ 21.595 moles

Now

1 mole = 968/21.595 = 44.826 g

The mass of one mole of the substance = 44.826 g

So,  the mass of one mole of the substance is closely related to the mass of one mole of CO₂ i.e.  44.01 g/mol.

It is also useful in high-temperature thermometers, barometers, pharmaceuticals, and nuclear medicine tests. Which electron configuration represents the electrons in an atom of gallium at ground state? O1s 2s22p63s23p64524d104p? O 182 2s22p63s23p64s24p1 o 1s 2s22p63s23p64823d104p? O 182 2s22p63s23p64s3​

Answers

The ground state configuration : 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹

Further explanation

Electrons can move the shell up or down by releasing energy or absorbing energy  

It can be concluded that there are 2 conditions:  

Ground-state is the state of electrons filling the shell with the lowest energy levels.  

Excited-state is the state of electrons which occupies a higher energy level  

The state of excited electrons can be seen from the presence of electrons which do not fill the shell completely but fill the shell afterward  

Gallium (Ga) is a metal located in group 13, p-block and  period 4

Atomic number : 31

If we look at the options:

options 1,2 and 3 do not conform to Aufbau principle(Electrons occupy orbitals of the lowest energy level  ), because 3d orbitals do not exist and the number of electrons is also not 31

So that the most appropriate electron configuration is:

1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹ = 31 electrons

or we can write : [Ar] 4s² 3d¹⁰ 4p¹

Not all protists use flagella or cilia to move. Give an example of another way protists move and identify the type of protist that uses that mode of movement.​

Answers

Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

A. 56 Co and 580
B. 57Co and 58Ni
c. 57Fe and 58 Ni
D. 57Mn and 57Fe

Answers

Answer:

B

Explanation:

Mass number  = number of neutrons + number of protons

Atomic number is the number of protons in the nucleus.  

58Ni   : 58 is the number of neutrons + number of protons

atomic number of Ni is 28.  Thus,  58 -28 = 30 neutrons

57Co ;  57 is the number of neutrons + number of protons

number of Co is 27. Thus, 57 – 27  = 30 neutrons

IUPAC name for BaSO3

Answers

Answer:

Barium Sulfite

Explanation:

Barium Sulfite

The IUPAC name for BaSO₃ is barium sulfite.

"Ba" stands for barium, which is the chemical symbol for the element with atomic number 56. Barium is an alkaline earth metal and belongs to Group 2 of the periodic table.

"SO₃" stands for sulfite, which is a polyatomic ion composed of one sulfur atom (S) and three oxygen atoms (O). The chemical formula for the sulfite ion is SO₃²⁻. The sulfur atom in the sulfite ion has a +4 oxidation state.

When barium (Ba) reacts with the sulfite ion (SO₃²⁻), they combine to form barium sulfite (BaSO₃). The balanced chemical equation for the reaction is:

Ba²⁺ + SO₃²⁻ → BaSO₃

Barium sulfite is an ionic compound, where the Ba²⁺ ion and the SO₃²⁻ ion are held together by electrostatic attractions (ionic bonds). In its solid form, barium sulfite appears as a white crystalline powder.

Answers

Answer:

The correct options are;

1) Heat

2) Atoms

Explanation:

The heat required to raise a unit mass of a substance by one degree which is the specific heat capacity of the substance, is a quantity characteristic of a given substance and the amount of temperature change experienced by the substance when an amount of heat energy transferred to the substance is a function of the mass of the substance, which is a function of the number of atoms present in the substance.

So also, the total thermal energy that is stored by a substance, that causes a given amount of temperature change, is a function of the heat capacity of the substance.

Answers

Answer:

Oxgen- cannot be separated

Water - chemical change

Gold - cannot be separated

Carbon Dioxide - chemical change

Carbon​ - cannot be separated

Explanation:

A pure substance, which can either be an element or a compound, contains only one type of such element or compound. In opposition to a mixture, pure substances cannot be separated by physical means.

- Elements as a pure substance cannot be separated because it contains only one type of atom. However, compounds contain two or more types of atoms, and hence, can only be separated into its individual atoms via chemical means.

In this question, oxygen (O2), Gold (Au) and carbon (C) are all elements and hence cannot be separated. Carbon dioxide (CO2) and water (H2O) are compounds because they contain two different atoms respectively, hence, can be separated into individual atoms.

Then one day a colleague sent him a copy of an inscription that had been found in the ruins of a temple on the Nile River island of Philae. Written in both hieroglyphs and Greek, the inscription was a royal decree issued by Pharaoh Ptolemy VII and his Queen, Cleopatra II. (This was not the famous Cleopatra, but an earlier one.) The Greek forms of Ptolemy and Cleopatra, like the English, had several letters in common. However, Champollion corrected Thomas Youngs mistake and spelled the first name as Ptolmis.
