What is a disadvantage of using a structural model to show a chemical compound? Structural models provide minimal three-dimensional information. Structural models do not identify the number and type of each atom. Structural models cannot distinguish between single, double, and triple bonds. Structural models cannot distinguish between different isomers of a compound.

Answers

Answer 1

Answer: The answer is the first: that structural models provide minimal three-dimensional information. This is because the ball-and-stick model cannot show the actual size of the atoms depicted in the model. You also cannot see the actual bond lengths between the atoms. This, then, limits the accuracy of the model and fails to precisely portray how the chemical compounds being shown are like in all actuality. Thus, though you do see a three-dimensional picture of the chemical compound, this picture is not completely accurate and is not scaled to size.

What volume of hydrogen is necessary to react with five liters of nitrogen to produce ammonia? N2 + 3H2 --> 2NH3

Answers

Volume of hydrogen required to produce ammonia = 3*5 = 15L
since, 1 mole of nitrogen reacts with 3 moles of hydrogen to produce ammonia.
Amount of ammonia produced = 2*5 = 10L as 1 mole of nitrogen produces 2 moles of ammonia

Solutions of aluminum nitrate and sodium sulfate react to form sodium nitrate and aluminum sulfate. Classify this reaction. 2AL(NO3)3(Aq)+3Na2SO4(Aq) ---> AL2(SO4)3(s)+6NaNO3(aq)

A) synthesis
B) decomposition
C) single replacement
D) double replacement

Answers

Answer:

Double replacement.

Explanation:

In the given reaction, there is not synthesis of compound.

The decomposition reactions are those in which a compound dissociates into simpler molecules or ions.

So the given reaction is not decomposition even.

In single replacement reactions, there is replacement of one group from a compound to other compound or element or ion.

Here two groups are being replaced (sulfate and nitrate) so the given reaction will be classified as double replacement.

2 Al(NO₃)₃ + 3 Na₂SO₄ = Al₂(SO₄)₃ + 6 NaNO₃

Aluminium Nitrate + Salt Cake = Aluminium Sulfate + Sodium Nitrate

Answer D ( double replacement )

B.
a pure substance that does not have a fixed volume or shape.

C.
an unevenly distributed mixture of two or more components.

D.
an evenly distributed mixture of two or more components.

Answers

Answer D, an evenly distributed mixture of two or more compounds.
This is because a solution requires a solvent and solute, which rules out answers A and B, as it means it cannot be pure.

d is the answer solution is a mixture of two or more components

Answers

Answer : Option B) Plant stomata opening and closing to maintain homeostasis.

Explanation : Claude Bernand was a French Physiologist who first discovered about "homeostasis" which is defined as the controlled stability of the internal milieu, or internal environment, of cells and tissues in plants.

In plants stomatal opening and closing was done for maintaining homeostasis with the external and internal plant environment.

Answer:

B) plant stomata opening and closing to maintain homeostasis
