Answer:
In diagram you have to show the electrons(dots) near to the more electronegative element by this you can show that this is an ionic bond.
Explanation:
¹/3 C3H8(g) + ⁵/3 O2(g)
Explanation:
The coefficient before every molecule is representative of the number of moles. We can represent it in ration form so as to calculate the question;
C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(l) means;
For every 1 mole of C₃H₈(g) and 5 moles of O₂(g) produces 3 moles of CO₂(g) and 4 moles of H₂O(l).
Therefore to produce 1.00 mole of CO₂(g);
We represent it in ratio;
C₃H₈(g) : CO₂(g)
1 : 3
What about ;
? (x) : 1
We cross multiply;
3x = 1 * 1
X = 1/3
We evaluate the same for O₂;
O₂(g) : CO₂(g)
5 : 3
What about
? (x) : 1
3x = 5 * 1
x = 5/3

Answer:
Y: tRNA
Z: DNA
Explanation:
This question involves two different nucleic acid molecules that are involved in protein production. Xavier used a chart to highlight the functions these nucleic acids perform during protein synthesis.
- Transfer RNA known as tRNA is a type of RNA molecule found in the ribosomes. It functions to read the mRNA codon and carry corresponding amino acid to the ribosomes for linking with one another. Based on this, "Y" on the chart is a tRNA molecule.
- Deoxyribonucleic acid, also known as DNA, is a molecule found in the NUCLEUS whose function is to store the genetic information in the cell. DNA carries the information needed for the synthesis of protein. Based on this, Z is a DNA molecule.
b. ethane (C2H6), a nonpolar covalent compound
Explanation:
The substance that would most likely need to cool to the lowest temperature before it condenses is ethane, a non-polar covalent compound.
Ethane in liquid form has very weak attractive forces binding the molecules together.
To form and change state, all the molecules must be brought very close together under very high pressure and low temperature. Else, they will not attract one another.
- Ionic crystal lattice forces as seen in KBr are strong attractive forces. As a substance such as KBr begins to condense, they begin to attract one another with a very strong force even before they cool to their least temperature.
- Ammonia has strong intermolecular hydrogen bonds in its structure which binds them together. The attraction is great between the hydrogen of one molecule and the nitrogen of another.
- In ethane we have a weak attraction.
