Answers
Answer:
Assertion (A) is true
but reason (R) is false.
Explanation:
If we look at the assertion closely, it is true that a sublime substance changes from solid to gas without passing through a liquid state. Naphthalene, camphor, iodine and ammonium chloride are some common examples of the substances which undergo sublimation.
However, not all solids first pass through a liquid state before converting to gas. Sublime solids such as those listed above passes directly from solid to gas without passing through a liquid state.
Hence the assertion is true but reason is false.

Explanation:
If 2.28 g C8H18 reacts with 7.00 g of Oz, predict the mass of CO, that can be produced and
identify the limiting reactant. Explain how you got your answers.
Unbalanced equation: C8H180 + 026) • CO26) + H₂O
Answers
Answer:
O₂ is limiting reactant and 6.17g CO₂ can be produced
Explanation:
Based on the balanced reaction:
C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O
1 mole of C₈H₁₈ reacts with 25/2 moles O₂.
To solve this question we must convert the mass of each reactant to moles and, using the balanced reaction, we can find limiting reactant. With moles of limiting reactant we can find the moles of CO₂ and its mass as follows:
Moles C₈H₁₈ -Molar mass: 114.23g/mol-
2.28g * (1mol / 114.23g) = 0.0200 moles C₈H₁₈
Moles O₂ -Molar mass: 32g/mol-
7.00g * (1mol / 32g) = 0.219 moles O₂
For a complete reaction of 0.0200 moles C₈H₁₈ are needed:
0.0200 moles C₈H₁₈ * (25/2moles O₂ / 1mole C₈H₁₈) = 0.250 moles of O₂ are needed.
As there are just 0.219 moles, O₂ is limiting reactant.
Moles of CO₂ that can be produced:
0.219 moles O₂ * (8moles CO₂ / 25/2moles O₂) = 0.140 moles CO₂
The mass is -Molar mass CO₂: 44.01g/mol-:
0.140 moles CO₂ * (44.01g / mol) =
6.17g CO₂ can be producedHow does genetic variation make a community more stable? Include explanations of how genetic variation is related to the struggle to survive, differential reproductive success, heredity, natural selection, and evolution
Answers
Answer:
If you have genetic variation then a community is more likely to survive because the population is more likely to have individuals who are fine if there are environmental changes. Then natural selection will happen and the species will evolve to he adapted to the new environment. If everyone in a population has the same genetics, than one thing could take them all out.

Balance the following equations.

B) CaCO3 + 2HCl → CaCl2 + H2O + CO2
C) CaO + H2O → Ca(OH)2
D) 3Ag + 4HNO3 → 3AgNO3 + H2O + NO2
Explanation:
A) Mg + H2SO4 → MgSO4 + H2
The equation is already balanced because the number of each element in the left hand side is already equal to that in the right hand side.
B) CaCO3 + 2HCl → CaCl2 + H2O + CO2
This equation is balanced by putting 2 in front of HCl on the left hand side to balance the elements on the right hand side.
C) CaO + H2O → Ca(OH)2
Thus equation is already balanced because the number of each element in the left hand side is already equal to that in the right hand side.
D) 3Ag + 4HNO3 → 3AgNO3 + H2O + NO2
This equation is balanced by putting 3 in front of Ag and 4 in front of HNO3 on the left hand side while we put 3 in front of AgNO3 on the right side to balance the elements on the right hand side.

Describe how nucleic acid basis pair up
Answers
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.

1.0 moles of an ideal gas are held in a container under 2.0 atm of pressure and 310 K. What must be the volume of this container?
Answers
Answer:
12.7 L (3 s.f.)
Explanation:
Since it is an ideal gas, we can apply the ideal gas law:
[tex]\boxed{pV=nRT}[/tex]
☆ where p= pressure
V= volume
n= number of moles
R= ideal gas constant
T= temperature
Substitute all the given information into the formula:
2V= 1(0.08206)(310)
2V= 25.4386
V= 25.4386 ÷2
V= 12.7 L (3 s.f.)
Further explanation:
The ideal gas constant, R, has different values depending on what units are being used. Two examples are listed below:
[tex]• \: 0.08206 \: L \: atm ^{ - 1} \: mol \: K[/tex]
[tex]• \: 8.314 \: J \: {mol}^{ - 1} \: {K}^{ - 1} [/tex]
In the above question, we use the value 0.08206 because the pressure was given in atm and the temperature was given in Kelvin. Thus, the unit used for volume is L.
Answer: 12.7 L
Explanation:
P=2.0atm
V= ???
n=1.0 mol
R= 0.0821
T= 310K
PV=nRT--> (2)V=(1)(0.0821)(310)
V=12.7 L

Relatively slow rates of chemical reaction are associated with which characteristic?
A)
High temperature
B)
Low activation energy
C).
The presence of a catalyst
D)
Strong bonds in reactant molecules
Answers
Option D : Strong bonds in reactant molecules
The strong bonds in reactant molecules sometimes needs extra energy to weaken the bond and proceed the reaction. Hence, option D is correct.
What is reaction rate ?The rate of a reaction is the rate of decrease in concentration of the reactants or decrease in concentration of the reactants or increase in the concentration of the products.
The minimum energy required to overcome the barrier potential of a reaction is called its activation energy. Hence, lower the activation energy higher will be the reaction rate.
High temperature and presence of catalyst also leads to higher rate. Strong bonds in reactants needs higher energy to weaken the intermolecular force. Thus, slower the reaction rate.

why does solid silver, Ag, conducts electricity while solid silver chloride, AgCl, does not.
Answers
Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.
Explanation:
Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.
As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.
Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.
As a result, silver chloride is not able to conduct electricity.
