The difference between ideal gases and real gases are most pronounced under conditions of inter molecular forces.
Difference between ideal gases and real gases are discussed below :
Real gases differ from ideal gases thanks to the presence of inter molecular forces, which cause the molecules of a true gas to deviate from perfect random motion.
As a result, real gases deviate from the perfect gas law at high densities and low temperatures, where the results of inter molecular forces are more pronounced.
So, the difference between ideal gases and real gases are most pronounced under conditions of inter molecular forces.
What are inter molecular forces?
The attractive forces that exist between molecules are liable for many of the bulk physical properties exhibited by substances.An inter molecular force (IMF) (or secondary force) is that the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other sorts of neighboring particles, e.g. atoms or ions.

What is the nucleotide sequence of an mrna strand that has been transcribed from the dna sequence ggtagc?
CCAUCG is the nucleotide sequence of an mrna strand that has been transcribed from the DNA sequence ggtagc.
What is a nucleotide sequence?Transfer RNAs interact with the ribosome system to translate a nucleic acid sequence, known as a messenger RNA or mRNA, into the protein it encodes. Transfer RNAs partition the nucleic acid sequence into triplet codons, each of which specifies one amino acid, by binding to three nucleotides at once. The sequence does not contain punctuation signals to indicate which reading frame should be used, hence the nucleic acid can be read in three different phases or reading frames depending on the point at which division into codons begins. An addition or deletion in the nucleic acid sequence that changes the translation process from one reading frame to another is known as a frameshift mutation.To know more about the nucleotide sequence, refer:

A lone pair must reside in which orbital type(s) to participate in resonance/conjugation/delocalization?
If a lone pair is participating in resonance, this capability the atom is both Sp2 or Sp hybridized. Looking at the Sp2 case, that ability there are 3 Sp2 orbitals and one P orbital. Assuming there is no formal cost on the atom, the three hybrid orbitals are used for bonding and the lone P-orbital holds the lone pair. Sp3 orbitals are no longer involved with resonance so the lone pair worried in resonance should never be in an Sp3 orbital.

The correct option is (e) none of these ,Valency is the ability of an element to combine.
What is Valency?Valency is the ability of an element to combine. Elements in the same group of the periodic table have the same valency. An element's valency is determined by how many electrons make up its outer shell.
A property of an element called "valency" defines how effectively it can meld with other elements. It is a way to count how many electrons are in an atom's outermost shell.
An atom's stability is determined by its valence electrons. Additionally, valence electrons are in charge of an atom's stability. The Octet Rule states that atoms often gain or lose electrons to reach the octet state, which is defined as having eight electrons in their valence shell. They stabilise at this stage.

1. We have new knowledge of how charge can be transferred from one object to another
(water + balloon; balloon + wall; tape). How might that information help us explain the
differences we noticed when we tested the conductivity of deionized water, salt water, and
sugar water?
Charge can be transferred from one object to another in three way conduction, polarization, and friction
Whenever electrons are transferred between objects, neutral matter becomes charged and three ways this can occur are referred to as conduction, polarization, and friction conduction means when there is direct contact between materials that differ in their ability to give up or accept electrons when two different materials are rubbed together, there is a transfer of electrons from one material to the other material and this causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer)
Here given object is water + balloon; balloon + wall; tape then you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon the wall is now more positively charged than the balloon and we tested the conductivity of deionized water positively charged

3.63g of O2 is consumed in the combustion of 1.00 g of propane.
Propane, c3h8, is a common fuel used for cooking and home heating.
C3H8 + 502---> 3CO2 + 4H20.
The combustion equation must first be balanced as illustrated above. The law of constant proportions can then be used to deduce that for every 1 mol of C3H8, there will be 5 mol of O2.
Using significant figures,
1 mol C3H8 -------> 44 g
1 mol O2 ------> 32g x 5 = 160
