Can an Atom be broken down into a smaller substance? Yes or No Explain.

Answers

Answer 1
Yes it can as it’s made of protons neutrons and electrons which is how we break the atoms down
Answer 2

Answer:

Yes

Explanation:

A atom is made out of 3 elements, protons which are positive charges, electrons which are negative charges that swirl around the atom, and a neutron with a neutral charge. The nucleus of the atom is basically the center of the atom.

Explanation:

May I please have brainiest?

Answer:

The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1". In general it is known that nonmetals are very poor conductors of heat and electricity. The nonmetals that are solid are normally very brittle and has very little or no metallic luster at all. Nonmetals are highly reactive and show variety of chemical properties. It can also be pointed out that the nonmetals gain electrons very easily.

What physical property of the metal rods was being tested during step 4 of the procudure?

4. Measure and record how long it takes heat from the hot plate set on "high" to melt the wax ball.

A.
magnetism
B.
thermal conductivity
C.
electrical conductivity
D.
density

Answers

Answer:

B.  thermal conductivity

Explanation:

They physical property being tested during the fourth step is the thermal conductivity of the materials.

Thermal conductivity is the ability of a body to transmit heat energy from one place to another.

Since we are measuring how long it takes for heat from the hot plate to reach the wax ball, this is a typical experiment for measuring thermal conductivity. Most metals are good conductors and heat energy moves fast in them.Non-metals are poor conductors with low thermal conductivity.

A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.

Answers

since 73% of the isotope is given, take 100%-73% to get the remaining % of the isotopes which is going to be 27%.

hence,

atomic weight= (73×59) + (27×62)

=4307+1302

=5609 amu

How many moles are in 5.25 X 10 25
atoms of Au?

Answers

Answer:

The answer is 87.21 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{5.25 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 87.2093023...[/tex]

We have the final answer as

87.21 moles

The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

The Valence Shell Electron Pair repulsion theory gives us a basis for predicting the shape of molecules. The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

In the image shown, We can see that in HCN , carbon is the central atom and is surrounded by two atoms and no lone pairs. Since there are two electron domains around the central atom, the molecule is linear.

In the second structure, BH3 has boron as its central atom. Three electron domains surround the central atom hence the molecule is trigonal planar.

How many moles of gold, a U, are in 3.60×10^-5 G of gold?

Answers

Explanation:

This is a conversion problem:

Using the molar mass of Gold (given in a periodic table) which is 196.97g/mol

you have

[tex](3.60*10^-5 g) *\frac{1moles}{196.97g}[/tex]

you always arrange the equation in a way to cancel whatever you don't want (grams) and leave what you do want (moles). Here grams cancel (top and bottom), so you're left with:

(use the given density as the conversion factor to calculate the wanted measurement).
Sign out

Answers

Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume

Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams

Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL

Calculate the average atomic mass of unknown element X. You determine that isotope 127X makes up 80%, isotope 126X makes up 17%, and isotope 128X makes up 3%.

A. 127.10 amu
B. 126.86 amu
C. 127.54 amu
D. 126.20 amu

Answers

Answer:

Option B. 126.68 amu

Explanation:

The following data were obtained from the question:

Isotope A (¹²⁷X):

Mass of A = 127

Abundance (A%) = 80%

Isotope B (¹²⁶X):

Mass of B = 126

Abundance (B%) = 17%

Isotope C (¹²⁸X):

Mass of C = 128

Abundance (C%) = 3%

Average atomic mass of element X =.?

Th4 average atomic mass of X can be obtained as follow:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(127 × 80)/100] + [(126 × 17)/100] + [(128 × 3)/100]

= 101.6 + 21.42 + 3.84

= 126.68 amu

Therefore, the average atomic mass of X is 126.68 amu

A sample of N2H4 has a mass of 25g. Identify the numerical quantity that is needed to convert the number of grams of N2H4 to the number of moles of N2H4. (You do not need to do the actual calculation.)

Answers

Answer:

Molecular Mass

Explanation:

It's asking for the numerical quantity. That quantity would be the Molecular Mass. Take the sample mass and divide it by the molecular mass to get the number of moles.

(14g N * 2) + (1g H *4) = 32g / mol of N2H4

To get # of moles, divide the sample mass by the molecular mass

25g / 32g = 0.78125 moles

The number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.

What is an Atomic number?

An atomic number may be defined as the number of protons in the nucleus of an atom that significantly represents the characteristic of a chemical element and determines its specific place in the modern periodic table.

According to the modern periodic table, an element that has an atomic number of 53 is known as Iodine. Its electronic configuration is [tex]1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^1^0, 4p^6, 5s^2, 4d^1^0, 5p^5[/tex]. Thus, according to this electronic configuration, the total number of d electrons are [tex]3d^1^0 and 4d^1^0[/tex].

Therefore, the number of d electrons that an atom of atomic number 53 possess are 20. Thus, the correct option for this question is 5.
