PLZ ANSWER WILL GIVE BRAINEST Based on the information in the table, which elements are most likely in the same periods of the periodic table?

-Boron and carbon are likely together in one period because they have very close atomic numbers, while gallium and germanium are likely together in another period because they have very close atomic numbers.

-Aluminum, boron, and carbon are likely together in one period because they were first isolated in the first half of the 1800s, while gallium and germanium are likely together in another period because they were first isolated in the second half.

-Boron and carbon are likely together in one period because they each end in “-on,” while aluminum, gallium, and germanium are likely together in another period because they each end in “-ium.”

-Aluminum, boron, and gallium are likely together in one group because they have the same number of valence electrons, and carbon and germanium are likely together in another group because they have the same number of valence electrons.

Calculate the number of moles for 12.044*10^23 number of helium atoms

Answers

Answer:

Explanation:

number of moles=number of particle (atoms)/avogadro number (NA)

we know that avogadro number is equal to 6.23*10^23

given number of atoms=12.044*10^23

therefore

moles=12.044*10^23/6.23*10^23=1.9=2

Density is an intensive physical property because the density of a given substance does not change with the size of the sample. (2 points)
True
False

Answers

Answer:

True

Density = mass/volume

Suppose that a block has a mass of 20 g and a volume of 20 cm^3.

Density = 20 g/20 cm^3 = 1 g/cm^3

Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.

The density of the half-block is

Density = 10 g/10 cm^3 = 1 g/cm^3

The density stays the same, even though the size of the sample has changed.

Explanation:

Answer:

✅True

Explanation:

Density is an intensive physical property because the density of a given substance does not change with the size of the sample.

29.4 mL of an CH3COOH solution were titrated with 18.5 mL of a 0.0175 m LiOH solution to reach the equivalence point. What is the molarity of the CH3COOH solution

Answers

Answer:

0.11 M

Explanation:

The computation of molarity of the CH3COOH solution is shown below:-

[tex]M_2 = \frac{M_1V_1}{V_2}[/tex]

Where,

[tex]M_1[/tex] = Molarity of LioH = 0.0175

[tex]V_1[/tex] = Volume of LioH = 18.5 ml

[tex]V_2[/tex] = Volume of CH3COOH = 29.4 ml

Now, we will put the values into the formula

[tex]= \frac{0.0175\times 18.5}{29.4}\\\\ = \frac{0.32375}{29.4}[/tex]

Which gives result

= 0.011 M

Therefore for computing the molarity of the CH3COOH solution we simply applied the above formula.

Answer:

Gold

Explanation:

water = H2O(3 atoms)

Sugar = C12H22O11 (45 atoms)

Salt = NaCl ( 2 atoms)

Gold = Au ( 1 atom)

A substance that is composed of only one type of atom is gold. Thus, the correct option for this question is D.

What is an atom?

An atom may be defined as the smallest unit of any matter that has the ability to form a chemical element. An atom may also be characterized as a particle of matter that uniquely illustrates a chemical element.

Water is composed of two atoms which are hydrogen and oxygen. Its chemical formula is [tex]H_20.[/tex] Sugar is a complex compound that consists of atoms of Carbon, hydrogen, and oxygen. Its chemical formula is [tex]C_6H_1_2O_6.[/tex] Salt typically consists of atoms of sodium and chlorine. Its chemical formula is NaCl.

Therefore, gold is a substance that is composed of only one type of atom. Thus, the correct option for this question is D.

Answers

Answer:

The answer is

22.63 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 837.21 g

volume = 37.00 mL

The density of the substance is

[tex]Density = \frac{837.21}{37} \\ = 22.62729[/tex]

We have the final answer as

22.63 g/mL

The forces between water molecules are stronger than the forces between ethanol molecules. Which liquid would probably be most difficult for an insect to walk on?

Answers

An insect would have a harder time walking on ethanol than it would water. Water has stronger intermolecular forces which leads to higher surface tension. The higher surface tension allows for the insect to be easily supported

Answer:
An insect would have an easier time walking on the surface of water than on the surface of ethanol.
Water’s stronger intermolecular forces lead to higher surface tension.
Higher surface tension allows water to support the insect.

Answers

Answer:

Explanation:

make them have a common denominator

3/4 needs to be times by 4

so it's

12/16 then you minus 7/16

the answer is

5/16

Answer: 5/16

Explanation:

Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.

If one end of an iron bar is heated, what causes thermal energy to transfer to the other end? a radiation b conduction c heat of fusion d convection

Answers

Answer:

Option B:

Conduction

Explanation:

Conduction is the transfer of heat from one molecule to another between two solids that are in direct contact with each other. For the conduction of heat to occur, the medium involved must be solid. This is because the molecules of solids are closely packed together and they cannot freely move about. The heat flowing through them can easily be passed on from one molecule to the other until it reaches all the parts of the object. This is exactly what will happen to the iron bar. Thermal energy from one end of the bar will get transferred between the molecules of the iron bar until it reaches the other end.

Convection on the other hand involves the transfer of heat through a liquid medium.

Radiation involves teh transfer of heat in a vacuum.

b) conduction
