An ideal gas is a gas composed of a large number of identical molecules that obey the ideal gas law.
What do you mean by Gas?
Gas is a state of matter made of atoms and molecules that are not bound together, allowing them to move freely and take the shape and volume of their container. It is one of the four fundamental states of matter (the others being solid, liquid, and plasma).
The heat exchanged in a two-step process is given by
q = CpΔT + (P1V1 – P2V2)
where Cp is the specific heat capacity of the gas, ΔT is the change in temperature, P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
For the two-step process,
q = CpΔT + (2.00 atm x 6.40 L – 2.50 atm x 3.20 L)
For the one-step process,
q = CpΔT + (2.50 atm x 6.40 L – 2.50 atm x 2.56 L)
The difference in q for the two-step process and the one-step process is
q2 – q1 = (2.50 atm x 3.20 L – 2.00 atm x 6.40 L)
q2 – q1 = (7.68 L atm – 12.80 L atm)
q2 – q1 = -5.12 L atm
Since 1 L atm = 101.3 J, the difference in q for the two-step process and the one-step process is
q2 – q1 = -5.12 L atm x 101.3 J/L atm
q2 – q1 = -517.4 J.
Hence, the difference is -517.4 J.

I’ve tried to do the problem but it’s confusing
Answer:
Explanation:
The equation for calculating the amount of heat released is:
q = mcΔT
where:
q = heat released (in joules)
m = mass of the substance (in grams)
c = specific heat capacity (in J/g·°C)
ΔT = change in temperature (in degrees Celsius)
Given:
m = 30 g
ΔT = 96°C - 25°C = 71°C
c = 4.184 J/g·°C (for water)
so
q = (30 g)(4.184 J/g·°C)(71°C) = 8.91*71 = 635.11 J
Therefore, 635.11 J of heat is released when 30g of water cools down from 96 degree celsius to 25 degree celsius
Note that this calculation is valid only if the process is adiabatic or no heat is exchanged with the environment.

how could you use this pattern to predict how the element may behave in a chemical reaction
Answer:
it can predict the properties of new elements, because it organizes the elements according to their atomic numbers.
Creating new elements is not a simple process. Scientists use a particle accelerator to smash light atoms into a thin metallic foil that contains heavier atoms. They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus.
When these heavy elements form, they are usually highly unstable. They decay so quickly that we don’t usually see the element itself. Instead, we see a decay product. In that respect, even new elements aren't always 'discovered' directly. In some cases, scientists haven’t synthesized enough of the element for us to know what the element even looks like! Nevertheless, we consider the elements as known. We name them and list them the periodic table.
For example, in 2003, scientists first observed element 115 (ununpentium, Uup) They bombarded americium-243 with calcium-248 ions and produced four atoms of Uup, which lived for less than one fifth of a second.
₂₀ ⁴⁸Ca + ₉₅²⁴³Am → ₁₁₅²⁸⁸Uup + 3 ₀¹n
It took until September 2013 for the discovery to be confirmed, and about 50 atoms have been synthesized to date.
We can predict the properties of Uup because the Periodic Table organizes elements according to their atomic number.

How many moles of sulfuric acid (H₂SO4) are needed ?
Based on the reaction’s stoichiometry: 2 LiOH + H2SO4 Li2SO4 + 2 H2O
It is obvious that when 2.0 moles of LiOH react with 1.0 mole of H2SO4, 1.0 mole of Li2SO4 and 2.0 moles of H2O are produced.
Making use of cross multiplication:
1.0 mole of H2SO4 totally interacts with LiOH (2.0 moles)
2.0 mole of H2SO4 is required to totally react with 6.8 mole of LiOH.
The mole of H2SO4 = (1.0 x 6.8) / (2.0) = 3.4 mole of H2SO4.

Select True or False: When lead-209 undergoes beta decay the balanced nuclear equation for this reaction is:
The statement is False, when lead-209 undergoes beta decay. As the nuclear equation is n ---> p + e- + antineutrino.
Lead-209 is an atom that contains 82 protons and 127 neutrons in its nucleus, meaning that lead-209 is not a neutron. Neutrons are particles that are found in the nucleus of atoms and have no charge. Therefore, lead-209 can't undergo beta decay by emitting a neutron. Beta decay occurs when an unstable nucleus emits a beta particle and an antineutrino, changing the number of protons in the nucleus. The balanced nuclear equation for the beta decay of lead-209 would be Pb-209 (atomic number = 82) --> Bi-209 (atomic number = 83) + e- + antineutrino. The Bi-209 is a isotope of bismuth, which has one more proton than lead-209 and the same number of neutrons.
