2. Which state of matter will take both the volume
and shape of the container that holds it?
A. gas
B. ice
C.liquid
D. Solid

Answers

Answer 1

Answer:

The answer would be C) a liquid.

Explanation:

If you were to pour a glass of water into a rectangular container, the water would fill up the container and be in the same shape as the container. That is becuase water flows and it doesn't harden up or take its own shape until it's frozen. The molecules are not tightly secure to each other so they are able to move freely.

Explanation:

find ionic compounds ​

Answers

Answer:

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

This is because metal cationic atom has two valence electrons. Non-metal anionic oxygen has six valence electrons Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it. Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon. So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.

Calculate the volume (in cm³) of 38.5 grams of platinum if the density of platinum is 21.5 g/cm³. Give your answer to 2 decimal places

Answers

Answer:

[tex]\boxed {\boxed {\sf v\approx 1.79 \ cm^3}}[/tex]

Explanation:

The formula of density is:

[tex]d=\frac{m}{v}[/tex]

If the formula is rearranged for volume, it becomes:

[tex]v=\frac{m}{d}[/tex]

The mass of the platinum is 38.5 grams.

The density is 21.5 grams per cubic centimeter.

[tex]m=38.5 \ g \\d= 21.5 \ g/cm^3[/tex]

Substitute the values into the formula.

[tex]v=\frac{38.5 \ g}{ 21.5 \ g/cm^3}[/tex]

Divide. Note that the grams (g) will cancel each other out.

[tex]v=1.79069767 \ cm^3[/tex]

Round to 2 decimal places (hundredth place). The 0 in the thousandth place tells us to leave the 9 in the hundredth place.

[tex]v\approx 1.79 \ cm^3[/tex]

The volume is about 1.79 cubic centimeters.

Answer:

D = 1.79 cm^3

Explanation:

Use the formula Volume = Mass / Density with what you've been given.

V = 38.5 g / 21.5 g/cm^3

V = 1.790697674 = 1.79 cm^3

What are the trends for atomic size and ionization? Explain why for each trend. Tell me the direction- up or down a group and across a period for each trend. Use the lecture, the video at the end of the lecture, or the guide for periodic trends to respond to this prompt.

Answers

Answer:

See explanation

Explanation:

Atomic size increases down the group due to the addition of more shells.

As more shells are added and repulsion of inner electrons become more significant, atomic size increases down the group. However, across the period, atomic size decreases due to increase in effective nuclear charge without any increase in the number of shells. This causes increased attraction between the nucleus and the outermost shell thereby decreasing the size of the atom.

Ionization energy decreases down the group because the outermost electron is more shielded by inner electrons making it easier for this outermost electron to be lost. Across the period, ionization energy increases due to increase in effective nuclear charge which makes it more difficult to remove the outermost electron due to increased nuclear attraction.

Rank these elements from smallest to largest atomic radii: zinc, calcium, radium, and bromine.
Select one:
O a. calcium, radium, zinc, bromine
O b. calcium, zinc, bromine, radium
c. bromine, zinc, calcium, radium
d. bromine, zinc, radium, calcium

Answers

Answer:

The correct option is;

c. Bromine, zinc, calcium, radium

Explanation:

The atomic radii of the elements as arranged in the periodic table decreases across the period and increases down the groups

The location of each of the elements are;

Zinc: Period 4, Group 12

Calcium: Period 4, Group 2

Radium: Period 7, Group 2

Bromine: Period 4, Group 17

Therefore, the element with the largest atomic radius = Radium

The element with the smallest atomic radius = Bromine

Calcium comes before zinc on period 4, therefore, the atomic radius of calcium is larger than that of zinc

The rank of the elements from smallest to largest atomic radius is therefore;

Bromine, zinc, calcium, radium.

How many moles would there be in 500,000,000,000 atoms of silver? Show your calculation
and answer in unit

Answers

Answer: 3.01 * 10^35

Explanation:

500,000,000,000 * 6.02 * 10^23

There are 3 [tex]\rm \times\;10^3^5[/tex] moles of silver present in the 500,000,000,000 atoms of silver.

According to the concept of molar mass:

1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

500,000,000,000 atoms of silver can be written as:

5 [tex]\rm \times\;10^1^1[/tex] atoms of silver.

1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

5 [tex]\rm \times\;10^1^1[/tex] atoms = 5 [tex]\rm \times\;10^1^1[/tex] [tex]\times[/tex] [tex]\rm 6.023\;\times\;10^2^3[/tex] moles

5 [tex]\rm \times\;10^1^1[/tex] atoms = 30.115 [tex]\rm \times\;10^3^4[/tex] moles

= 3 [tex]\rm \times\;10^3^5[/tex] moles.

The moles of silver are present in the 500,000,000,000 atoms of silver are 3 [tex]\rm \times\;10^3^5[/tex] moles.

In experiment B. the iron filings weighed 2.0g at the beginning of the experiment
and the iron sulphide produced weighed 2.8g.
Explain this increase in mass.

Answers

Explanation:

The increase in mass is because the iron fillings have combined with a sulfide to produce iron sulfide and so the mass will increase.

In such a reaction like this, the mass of the reactants must be conserved. By so doing, the mass of reactants and products must be the same.

When two substances combine together, their masses added up to that of the individual masses. This helps to conserve the mass.

What are physical changes?

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

What is an atom?

An atom is the basic unit of every substances. Atoms combine together to form molecules, molecules then forms compounds and so on.

The inner core of an atom is called nucleus which contains positively charged particles namely protons and neutral particles neutrons. There are circular paths of fixed energy surrounding the nucleus.

The circular paths around the nucleus is called orbits through which the electrons are revolving. Electrons are negatively charged particles and they neutralize equal number of positive charges.

A neutral atom have equal number of protons and electrons and this number is called its atomic number. The sum of number of protons and neutrons is called the mass number.

Hence, an atom is made up of protons, electrons, and neutrons and option A is correct.

Polyacrylamide is used in manufacturing soft contact lenses. It consist of 50.69% carbon, 19.71% nitrogen, 7.09% hydrogen, and 22.51% oxygen. Calculate the empirical formula for polyacrylamide.

Answers

Answer: The empirical formula is [tex]C_3NH_5O[/tex].

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C = 50.69 g

Mass of N= 19.71 g

Mass of H = 7.09 g

Mass of O = 22.51 g

Step 1 : convert given masses into moles.

Moles of C = [tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{50.69g}{12g/mole}=4.22moles[/tex]

Moles of N=[tex]\frac{\text{ given mass of N}}{\text{ molar mass of N}}= \frac{19.71g}{14g/mole}=1.41moles[/tex]

Moles of H=[tex]\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{7.09g}{1g/mole}=7.09moles[/tex]

Moles of O = [tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{22.51g}{16g/mole}=1.41moles[/tex]

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C =[tex]\frac{4.22}{1.41}=3[/tex]

For N = [tex]\frac{1.41}{1.41}=1[/tex]

For H = [tex]\frac{7.09}{1.41}=5[/tex]

For O =[tex]\frac{1.41}{1.41}=1[/tex]

The ratio of C:N:H: O = 3:1:5:1

Hence the empirical formula is [tex]C_3NH_5O[/tex].
