Que es la materia y qué es el volumen que ocupa la materia?
Todo en un estado sólido de materia tiene una forma y una longitud distintas. El volumen de un objeto es la cantidad de espacio que ocupa. Un sólido es un bloque de madera que conserva su forma y volumen cuando se coloca sobre una mesa.

Answer:
67.3 kPa
Explanation:
We're focusing on pressure and volume of gases, so we can use our ideal gas law formula PV=nRT. Everything is constant except pressure and volume, but the values change when moving from city 1 to city 2, so we can say PV city 1= PV city 2.
We can simplify our formula to be P1V1=P2V2. This is specifically Boyle's Law, where if pressure increases (from city 1 to city 2) then volume decreases, thus we can say pressure and volume have an inverse/opposite relationship.
This is an important formula to understand, you can easily memorize it by referring to PV=nRT.
Let's plug in the values we know.
P1V1=P2V2
(101)(6) = (9)(V2)
Now let's solve for V2.
[tex]\frac{101 x 6}{9}[/tex] = V2
[tex]\frac{606}{9}[/tex] = V2
67.3 kPa = V2

According to the Gibbs free energy equation, G= H-T S, when could a high temperature make a reaction that was nonspontaneous at low temperature spontaneous
Answer:
For the reaction to be spontaneous at high temperatures, ΔG < 0 and, ΔH > 0 and ΔS > 0.
Explanation:
According to the Gibbs free energy equation, for the reaction to be spontaneous at high temperatures when it was not spontaneous at low temperatures, the free energy change ΔG < 0.
Since ΔG = ΔH - TΔS where ΔH = enthalpy change and ΔS = entropy change,
For ΔG < 0 at high temperatures, ΔH > 0 and ΔS > 0. That is both ΔH and ΔS are positive at high temperatures.
So, for the reaction to be spontaneous at high temperatures, ΔG < 0, and ΔH > 0 and ΔS > 0.
When ΔH and ΔS are both positive
How many grams of KCI can be dissolved in 63.5. g of water at 80
Answer:
35.8 g
Explanation:
Step 1: Given data
Mass of water: 63.5 g
Step 2: Calculate how many grams of KCl can be dissolved in 63.5. g of water at 80 °C
Solubility is the maximum amount of solute that can be dissolved in 100 g of solute at a specified temperature. The solubility of KCl at 80 °C is 56.3 g%g, that is, we can dissolve up to 56.3 g of KCl in 100 g of water.
63.5 g Water × 56.3 g KCl/100 g Water = 35.8 g KCl

The higher the effective nuclear charge, the greater the -------- exerted by the nucleus of the added electron?
Answer:
Pull
Explanation:
The higher the effective nuclear charge, the more the nucleus will be gaining protons. This process makes the electrons to be drawn closer to the positive charge of the nucleus.
Thus, it leads to a greater pull exerted by the nucleus on the added electrons.
1. Make a claim that answers the following question: "What is the
connection between the number of valence electrons and
chemical/physical properties?" *
Lets take an example to explain this
Sodium(Na) has 1 electron in its outer or valence shell hence it will lose it and become a cation say to Chlorine(Cl)
To form Sodium Chloride.
Since it is capable of losing electrons, Sodium becoems a metal and has properties of metal
Whereas Chlorine which has 7 electrons in its valence shell gains an electrons to become an anion
Hence it is a non metal
And has the properties of an anion

For the reaction of C 2H 4( g) with O 2( g), to form CO 2( g) and H 2O( g), what number of grams of CO 2 could be produced from 2.0 g of C 2H 4 and 5.0 g of O 2?
Answer:
4.58g of CO₂ could be produced
Explanation:
Based on the reaction:
C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)
1 mole of C₂H₄ reacts with 3 moles of oxygen to produce 2 moles of CO₂
To solve this question we must find the moles of each reactant in order to find limiting reactant. With limiting reactant we can find the moles -And the mass- of CO₂ produced:
Moles C₂H₄ -Molar mass: 28.05g/mol-
2.0g * (1mol / 28.05g) = 0.0713moles
Moles O₂ -Molar mass: 32g/mol-
5.0g * (1mol / 32g) = 0.156moles
For a complete reaction of 0.0713 moles of C2H4 are required:
0.0713 moles C₂H₄ * (3 moles O₂ / 1 mol C₂H₄) = 0.214 moles of O₂
As there are just 0.156 moles, O₂ is limiting reactant.
The moles of CO₂ produced are:
0.156 moles O₂ * (2mol CO₂ / 3mol O₂) = 0.104 moles CO₂
The mass is -Molar mass CO₂: 44.01g/mol-
0.104 moles CO₂ * (44.01g / mol) =

The amount of radioactive carbon-14 in a sample is measured using a Geiger counter, which records each disintegration of an atom. Living tissue disintegrates at a rate of about 13.5 atoms per minute per gram of carbon. In 1977 a charcoal fragment found at Stonehenge, England, recorded 8.2 disintegrations per minute per gram of carbon. Assuming that the half-life of carbon14 is 5730 years and that the charcoal was formed during the building of the site, estimate the date when Stonehenge was built
Answer:
4121 years
Explanation:
From;
0.693/t1/2 = 2.303/t log No/N
t1/2= half life of the carbon-14
No= count rate of the living tissue
N= count rate of the sample
t = age of the sample
0.693/5730 =2.303/t log (13.5/8.2)
1.21 * 10^-4 = 2.303/t * 0.2165
1.21 * 10^-4 = 0.4986/t
t = 0.4986/1.21 * 10^-4
t = 4121 years

A gas occupies 650.mL at STP. How many moles of gas are in the container?
Please help ((((
Explanation:
describe this guy standing
A gas occupies a volume of 500. Milliliters at a pressure of 38.0 kPa and a temperature of 298 K. At what temperature will the gas occupy a volume of 250. Milliliters and have a pressure of 76.0 kPa?
Answer:
A gas occupies a volume of 250 mL at a pressure of 76 kPa and a temperature of 298 K.
Explanation:
Charles's law states that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. This mathematical law expresses that the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Gay-Lussac's law says that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically says that the quotient between pressure and temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Finally, Boyle's law says that the volume occupied by a certain gaseous mass at constant temperature is inversely proportional to the pressure. This law is expressed mathematically as
P * V = k
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
[tex]\frac{P*V}{T} =k[/tex]
Analyzing an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1*V1}{T1} =\frac{P2*V2}{T2}[/tex]
In this case:
P1= 38 kPaV1= 500 mLT1= 298 KP2= 76 kPaV2= 250 mLT2= ?Replacing:
[tex]\frac{38 kPa*500 mL}{298 K} =\frac{76 kPa*250 mL}{T2}[/tex]
Solving:
[tex]T2*\frac{38 kPa*500 mL}{298 K} =76 kPa*250 mL[/tex]
[tex]T2=\frac{76 kPa*250 mL*298 K}{38 kPa*500 mL}[/tex]
T2= 298 K
A gas occupies a volume of 250 mL at a pressure of 76 kPa and a temperature of 298 K.

What the common uses for Rutherfordium???
Answer:
welcome
Explanation:
Uses of Rutherfordium
Because rutherfordium is made within the lab, there are not very many uses for this element commercially. On the other hand, rutherfordium has been used within the laboratory setting to conduct research. Most elements that are highly radioactive are used for nuclear power and medicinal purposes.
Which change happens when a fan is turned on?
A. Electrical energy is changed into light energy
B. Heat energy is changed into mechanical energy
C. Mechanical energy is changed into sound energy
D. Electrical energy is changed into mechanical energy
Answer:
D. Electrical energy is changed into mechanical energy
Explanation:
When you turn on the fan, the electricity that is given through the power outlet allows the fan to have the available energy to spins the fan blades. By the fan's blades spinning, this is a movement that can be described as mechanical energy.
