Select all that are true regarding stereoisomers,constitutional isomers, and conformational isomers

1 answer:

8 0

Answer:To convert the model of one constitutional isomer to another constitutional isomer one needs to exchange 2 atoms/groups on different atoms.

To convert the model of one stereoisomer to another stereoisomer one needs to exchange 2 atoms/groups bonded to the same carbon.

To convert the model of one conformational isomer to another conformational isomer one only needs to rotate about single bond(s).

Explanation:

Constitutional isomers differ from each other in position of substituents. Hence if we interchange atoms or groups on two different atoms, we get constitutional isomers.

Stereo isomers posses different orientations in space. If two atoms or groups on the same carbon atoms interchange their spatial orientation, we have a different stereoisomer other than the original structure.

Conformers arise by free rotation across single bonds. Different conformers can be created by rotating single bonds.

What is the net ionic equation for the reaction shown below?

arsen [322]

Answer:

Ag⁺(aq) + Cl⁻(aq) → AgCl(s)

Explanation:

Chemical equation:

AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)

Balance chemical equation:

AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)

Ionic equation

Ag⁺(aq)+ NO₃⁻(aq) + Na⁺(aq)+ Cl⁻(aq) → AgCl(s) + Na⁺(aq)+ NO₃⁻(aq)

Net ionic equation:

Ag⁺(aq) + Cl⁻(aq) → AgCl(s)

The NO₃⁻((aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The AgCl can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.

Which is one way that analyzing ice benefits scientists who study ancient climates? Scientists can analyze frozen volcanic dust

aleksandr82 [10.1K]

Answer:

The correct option is;

Scientists can drill deep into the ice to collect ice cores which contain trapped atmospheric gases

Explanation:

The study of past climates also known as paleoclimatology, is accomplished by acquiring information from proxy data sources which are physical environment characteristics that are preserved through time to remake the conditions of past climate

Past physical environmental characteristics, from which information about ancient climate can be gained are stored in nature's climate variability records including, ice cores, rings in tree stems, fossil pollen, sediments found in the waters of the ocean

The proxy sources provide a means of understanding the conditions of ancient climate before advent of climate measurement.

Therefore, one way that analyzing ice benefits scientists who study ancient climates is that scientists can drill deep into the ice to collect ice cores which contain trapped atmospheric gases from past climates.

Julia notices that the ""check engine"" light comes on while driving her car on days with temperatures of over 100 degrees. what

aev [14]

Option b), Julia's car engine overheats when the outside temperature exceeds 100 degrees is the best plausible explanation for her “check engine” light coming on while driving her car on days with temperatures over 100 degrees.

<h3>Reasoning</h3>

The other options that the engine needs to be replaced, that it cannot withstand high temperatures, or that Julia cannot drive her car on days when it is over 100 degrees outside are not plausible explanations for the situation because that is not what it indicates. the expression “check engine”

On the other hand, option b) is a plausible explanation because the light that comes on with the "Check engine" indicator is due to a temperature sensor that the engine has and that is activated once a certain temperature is exceeded.

In this case, the sensor is sensitive to a temperature differential, since it is activated when the motor compares the degrees of internal temperature with the external one.

How many grams of ammonia are produced from 6 moles of nitrogen?

tia_tia [17]

How many grams of ammonia are produced from 6 moles of nitrogen?
Answer: The equation is 3H2 + N2 → 2NH3

If 6 moles of H2 gas react with N2 (assuming all reactants react)

6 * 2/3 moles of ammonia must be produced.

Therefore 4 moles of ammonia can be produced.

Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.
