What factor is mostly responsible for the form of matter?
time
temperature
pressure
weather
Temperature is mostly responsible for the form of matter. For instance, when raising the temperature you're adding energy. This energy gives the individual molecules and atoms the ability to overcome the forces that hold them together. This can be seen when a solid turns into a liquid or a liquid turns into a gas. However, when you're lowering the temperature you're removing energy. The lack of energy results in less movement from the atoms. Gases condense into liquid because the atoms don't have enough energy to stay away from each other. Liquids solidify because the atoms don't have enough energy to slide past each other and they get stuck in place. So in conclusion, temperature determines how how much energy atoms have that allow them to move at different speeds which determines the state of matter.
g If the pressure of each gas is increased at constant temperature until condensation occurs, which gas will condense at the lowest pressure
The question is incomplete; the complete question is;
If the pressure of each gas is increased at constant temperature until condensation occurs, which gas will condense at the lowest pressure?
A) Octane
B) Ethane
C) Butane
D) All the gases will condense at the same pressure
Answer:
Octane
Explanation:
If we study the table closely we will realize that octane has the greatest molecular mass among all the gases shown.
The greater the molecular mass, the lower the pressure required for the condensation of the gas. Hence, the lowest pressure is required for the condensation of octane at constant temperature.
A person drops two objects from the same height. one object weighs 15 N and the other weighs 10 N
A The 10 N object has the same mass as the 15 N object
B The 15 N object has twice the mass of the 10 N object
C The 15 N object has more mass than the 10 N object
D The 10 N object has more mass than the 10 N object
Write the equation for the dehydration of the CoCl2 hydrate
As we will soon see in Section 4.5, gasoline is a complex mixture of alkanes and other hydrocarbons, and the term "octane rating" is used as a standard measure of the performance of engine fuel. In the petroleum industry, one area of interest is the use of catalysts to convert unbranched alkanes and branched alkanes with higher octane ratings (Journal of the Japan Petroleum Institute 2004, 47, 1–10). For example, heptane can undergo isomerization in the presence of suitable catalysts to give eight different constitutional isomers, all of which are branched alkanes with the molecular formula C7H16. Draw all eight constitutional isomers, making sure not to draw the same compound twice.
Answer:
Explanation:
C₇H₁₆ is heptane and it has nine isomers (n-heptane and the remaining 8 constitutional isomers). Constitutional isomers are compounds with the same molecular formula but different structural formula or atom connectivity.
The constitutional isomers of n-pentane are 2-methylhexane, 3-methylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane and 2,2,3-trimethylbutane. There structures are in the picture attached

what is the relationship between netforce and acceleration based on the situation?
Answer:
The net force is greater at the second situation as well as the acceleration due to the contribution of the second guy.
Explanation:
Hello.
In this case, since the net force is computed via adding all the exerted forces on a body, for the first situation we can see that the net force equals the force provided by that guy when pulling, whereas in the second situation the net force equals the force of both of the guys pulling the car:
[tex]F_N_1=F_1\\\\F_N_2=F_1+F_2[/tex]
For the acceleration, we can see that applying an extra force (due to the second guy) turns out into a greater acceleration, that is why the car at the second situation reaches the tree whereas the other one does not.

Electronic configuration PLZZZ GUYSS(sub shell distribution) for L shell will be .........................
Answer:
Shells
The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n). It is represented by the formula 2n2, where ‘n’ is the shell number. The shells, values of n, and the total number of electrons that can be accommodated are tabulated below.
Shell and ‘n’ value Max. Electrons in the Electron Configuration
K shell, n=1 2*12 = 2
L shell, n=2 2*22 = 8
M shell, n=3 2*32 = 18
N shell, n=4 2*42 = 32
L shell: n =2
hence,
2n²
= 2(2)²
i.e. 8 electrons can fit in the l shell
hence max no. of electrons is 8
so configuration in L shell is,
2, 8...

For the combustion of methane, CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) △H = -213
kcal/mol
How many kilocalories of energy are released from 5.0 mol of methane?
How many moles of methane are needed to give 100. kcal heat?
Answer:
1.-213(kcal/mol)*5mol=1065kcal
2.100/213 mol
a. The energy released from 5.0 mol of methane is -1065 kcal/mol.
b. The number of moles of methane needed to give 100. kcal heat is 0.4694 moles.
What is combustion?Combustion is a chemical process in which the element reacts with oxygen to produce heat and light. Burning of wood.
The equation of combustion of methane:
CH₄ (g) + 2O₂(g) ------> CO₂ (g) + 2H₂O (l)
a) Enthalpy of the reaction is H = -213 Kcal/mol
This means 213 Kcal heat is released in the burning of one mole of CH4
H reaction = [ H products ] - [ H reactants ]
Hr = [ H(CO₂)g + 2H(H₂O)l ] - [ H(CH₄)g ] = -213 kcal/mol
For 5 moles of methane:
5CH₄(g) + 10O₂(g) -----> 5CO₂(g) + 10H₂O(l)
therefore, new Hr = 5 x -213 = -1065 kcal/mol
H reaction = -1065 kcal/mol
b) 213 kcal is released per mole of Methane
then, to release 100 kcal we need, 100 / (213) = 0.4694 moles
Thus, the energy released is -1065 kcal/mol, and the number of moles is 0.4694 moles.

75 g of a metal is heated to a temperature of 99C. The metal is then placed in a calorimeter containing 145 g of water at a temperature of 25C. The temperature of the water in the calorimeter increase to a final temperature of 28C. What is the specific heat of the metal?
Answer:
0.34 J / g ⁰C
Explanation:
Let the specific heat of metal be s .
heat will be lost by hot metal and gained by water .
heat lost by metal = mass x specific heat x loss of temperature
= 75 x s x ( 99 - 28 ) = 5325 s
heat gained by water = mass x specific heat x gain of temperature
= 145 x 4.18 x ( 28 - 25 ) = 1818.3
heat lost = heat gained
5325 s = 1818.3
s = 0.34 J / g ⁰C

Which of the following situations best describes an ionic bond?
Two atoms each give up an electron, and an electrostatic force attracts them.
One atom gains an electron while the other atom loses an electron, and an
electrostatic force attracts them.
One atom gains an electron while the other atom loses an electron, and an
electrostatic force repels them.
Two atoms gain electrons and an electrostatic force attracts them.
The situation which best describes the ionic bond is “ One atom gains an electron while the other atom loses an electron, and an electrostatic force attracts them”.
What is an ionic bond?
An ionic bond is formed between two atoms by donating an electron from the electropositive atom and withdrawal of that electron by the second atom which is electronegative and thereby attaining stability by making their valency completed.
The electron loss-gain interaction make an electrostatic force of attraction between them, where the electrons from the electropositive atom is attracted towards the electronegative atom.
Thus the two atoms are bound together by the electrostatic force of attraction created by the electron donation. Hence, option b is correct.

A balloon containing methane gas has a volume of 1.03 L at 99.0 °C . What volume will the balloon occupy at 198 °C ?
Answer:
The balloon will occupy a volume of 1.32L.
Explanation:
Given the following data;
Original Volume, V1 = 1.03L
Original Temperature, T1 = 99°C
New Temperature, T2 = 198°C
To find new volume V2, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
[tex] VT = K[/tex]
[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]
Converting T1, from Celsius to Kelvin = 273 + 99 = 372K
Converting, T2, from Celsius to Kelvin = 273 + 198 = 471K
[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]
Making V2 as the subject formula, we have;
[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]
[tex] V_{2}= \frac{1.03}{372} * 471[/tex]
[tex] V_{2}= 0.0028 * 471[/tex]
V2 = 1.32L
Therefore, the balloon will occupy a volume of 1.32L at 198°C
