Liquid, Gas and Plasma

Explanation:

➨Think about it like this if you put a material made out of these and flipped it over which one would have the most effect of change in shape?

▶Liquid molecules slide past each other meaning they are not held in place.

▶Gas molecules are "excited" they bounce around everywhere meaning they are not held in place.

▶Plasma has no fixed shape or volume so it cant be held in place!

▶Solid molecules have a fixed shape so they cannot move on their own.

In the reaction given below, 23.5 grams of iron(III) oxide (Fe2O3) are reacted with excess carbon. What is the theoretical yield of iron metal?
2 Fe2O3 + 3 C --> 4 Fe + 3 CO2

If 14.5 grams of iron are recovered when the reaction is complete, what is the percent yield?


**Both answer should be written as XX.X

Answers

Answer:

Theoretical yield = 16.76 g

Percent yield = 87%

Explanation:

Given data:

Mass of iron oxide = 23.5 g

Theoretical yield of iron = ?

Actual yield of iron = 14.5 g

Percent yield of iron = ?

Solution:

Chemical equation:

2Fe₂O₃ + 3C     →  4Fe + 3CO₂

Number of moles of iron oxide:

Number of moles = mass/molar mass

Number of moles = 23.5 g/ 159.69 g/mol

Number of moles = 0.15 mol

Now we will compare the mole of iron oxide with iron metal.

                      Fe₂O₃         :            Fe

                         2              :              4

                      0.15            :          4/2×0.15 = 0.3

Mass of iron:

Mass = number of moles × molar mass

Mass = 0.3 mol × 55.85 g/mol

Mass = 16.76 g

Percent yield:

percent yield = (actual yield / theoretical yield)× 100

Percent yield = (14.5 g / 16.76 g) × 100

Percent yield = 0.87 × 100

Percent yield = 87%

Explanation:

The correctly describes the gases in containers R, S, and T is  R = mixture S = element and  T = compound. Hence option d is correct.

What are gases?

Gases are defined as the state of matter where particles often travel very swiftly, far apart from one another, and with little or no attraction to one another. They take up much more space than the liquids or solids from which they are formed, are simple to compress, and expand to fill their containers.

Particles make up all matter; these particles can be single atoms or atoms that have been chemically combined to form molecules. This fact allows us to divide matter into three general categories: elements, compounds, and mixtures. All the atoms in an element are of the same kind. A compound is created when more than one kind of atom is chemically bonded.

Thus, the correctly describes the gases in containers R, S, and T is  R = mixture S = element and  T = compound. Hence option d is correct.

How would the calculated concentration of the hci be affected if the sodium hydroxide were poured from ma beaker that contained some water before the naoh were added to it

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, the beaker that contained some water before NaOH were added means that the resulting solution in that beaker will be more dilute. When this diluted sodium hydroxide solution is added to HCl (not hci), the reaction below occurs

HCl + NaOH ⇒ NaCl + H₂O

The reaction above is a neutralization reaction. The concentration of the acid (HCl) will reduce when a base (sodium hydroxide) is added and will also reduce more because of the presence of more water (in the base) which normally reduces the concentration of ions present in an acid or a base to become more dilute.

The mass of calcium sulfite produced : 15 g

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

CaO + SO₂ → CaSO₃

mol CaO (MW=56 g/mol)

[tex]\tt \dfrac{7}{56}=0.125[/tex]

Because sulfur dioxide is an excess, so mol CaSO₃ based on mol CaO

From the equation, mol ratio of mol CaSO₃ : mol CaO=1 : 1, so mol CaSO₃ :

[tex]\tt \dfrac{1}{1}\times 0.125=0.125[/tex]

mass CaSO₃ (MW=120 g/mol) :

what process creates deltas?

Answers

Explanation:

A delta is a process that forms by river deposition into an ocean or marine environment.

Sediments carried by rivers in their old stage are brought near the mouth of an ocean. As the velocity of the river reduces, sediments begins to settle out. Small river tributaries breaks out into the ocean. Delta forms at an interphase between a small and large body of water. The deposited sediments forms distinct shapes as they enter the larger body of water.

secondary alcohol (X) reacts with PCL5 to give alkyl halide (Y) which on dehydrohalogenation yield an alkene(Z).The alkene upon ozonolysis gives the mixture of ethanal and methanal.Identify X ,Y ,Z​

Answers

Answer:

X = 2-propanol

Y = 2-chloropropane

Z = propene

Explanation:

Secondary alcohol is an alcohol in which the carbon that the functional group (OH group) is attached to is also attached to two alkyl group. Examples are 2-propanol and 2-butanol.

The secondary alcohol referred to in the question here is 2-propanol and it reacts with PCl₅ as seen below

H₃C-CH-CH₃ + PCl₅ ⇒ H₃C-CH-CH₃ + HCl + POCl₃

        |                                     |

       OH                                Cl

The alkylhalide produced there is 2-chloropropane. Thus, we can see that X is 2-propanol and  Y is 2-chloropropane.

When this 2-chloropropane undergoes dehydrohalogenation (removal of hydrogen and halogen) an alkene is formed. The reaction is seen below

H₃C-CH-CH₃   (-HCl)    ⇒  H₃C-CH=CH₂

        |

       Cl

The alkene produced (as seen above) is propene.

Confirmation: When propene undergoes ozonolysis, the compounds produced are ethanal and methanal as seen in the equation below

                                                   O

                                                 /    \

H₃C-CH=CH₂ + O₃  ⇒  H₃C - CH  CH₂    [-O]  ⇒ CH + CH₂  

                                                 ||     ||                     ||        ||

                                                O    O                    O      O

The final products as seen above are methanal and ethanal

Composition of matter (compound, mixture, element)​

Answers

Explanation:

Matter can be classified into two broad categories: pure substances and mixtures. ... A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an elementOne useful way of organizing our understanding of matter is to think of a hierarchy that extends down from the most general and complex to the simplest and most fundamental (Figure 3.4.1 ). Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition (meaning that it is the same everywhere) and properties that are constant throughout the sample (meaning that there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter). A material composed of two or more substances is a mixture. Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date.

An element is a substance which can be split into simpler unit by ordinary chemical prcess.

Compound this is a pure substance that is composed of two or more element in a fixed and definite portion.

Mixture contains two or more constituents which can be easily separated by physical method.
