Identify the spectator ions in this reaction. Check all that apply. 2H+ + CrO4– + Ba2+ + 2OH– Ba2+ + CrO4– + 2H2O H+ CrO4– Ba2+ OH– 2H2O

Answers

Answer 1

Answer: Answer: CrO₄⁻ and Ba²⁺

Explanation:

1) Chemical equation given:

2H⁺ + CrO₄⁻ + Ba²⁺ + 2OH⁻ → Ba²⁺ + CrO₄⁻ + 2H₂O

2) Analysis

That is an oxidation-reduction equation (some species are been oxidized and others are being reduced).

The given equation is known as total ionic equation, because it shows all the species as ions that are part of the reaction.

2) Specator ions

Spectator ions are the ions that do not change their oxidation state and are easily identified as they are the same in the reactant and product sides.

Here the ions that are the same in the reactant and product sides are:

CrO₄⁻ and Ba²⁺

3) Addtitional explanation.

Once you identify the spectator ions you can delete them from the equation to obtain the net ionic equation , which in this case turns to be:

2H⁺ + 2OH⁻ → 2H₂O

But this is not part of the question; it is some context to help you understand the use of the spectator ions concept.

A solid precipitate is formed from the reaction of lead nitrate and sodium chromate. What would be the best method to separate this solid from the solution?

Answers

The correct answer is this one: "C. Filtration." For distillation and evaporation, it would leave the soluble salt behind as well. Filtration refers to the action or process of filtering something.
Here are the choices:
A. Distillation
B. evaporation
C. Filtration
D. Sorting

Explanation:

A precipitate is an insoluble solid that does not dissolve in a chemical reaction or or mixture.

For example, $Pb(NO_(3))_(2) + Na_(2)CrO_(4) \rightarrow PbCrO_(4) + 2NaNO_(3)$

Therefore, the precipitate formed can be separated out by filtration method.

As this method will most suitably extract the precipitate and separate it from the remaining solution.

What does it mean to say that momentum is conserved?

Answers

Conservation of momentum. So long as no external forces are acting on the objects involved, the total momentum stays the same in explosions and collisions. We say that momentum is conserved. You can use this idea to work out the mass, velocity or momentum of an object in an explosion or collision.

What type of Technology would you want to use to study the gas giant planets

Answers

To study the gas giants, scientists and space explorers used spacecraft and probes. And also, one of the breakthroughs, that made exploration in the outer planet much easier was the planet gravity assist concept wherein, a much smaller space craft is used to launch in order to cope up with the accelerated speed if a spacecraft approaches the planet.

Some people think that wind power should be used for all the electricity in the United States. Which argument could be used to dispute this idea?

Answers

Answer:

The arguments that could be used to challenge the idea of using wind power to provide electricity to the whole country is that there is a difficulty in capturing wind, wind power causes visual and sound impacts, as well as an impact on fauna.

Explanation:

Wind energy is a widely used method for obtaining power through wind power, which drives windmill and windmill-like mechanisms connected to a generator that produces electricity.

The main advantage of wind energy is that it is considered a clean energy, that is, obtained from renewable sources and without generating any kind of polluting waste during its production and consumption.

Although wind energy is one of the best options for obtaining energy from renewable and clean sources, it is possible to see some negative points of this technique. These negative points are:

Difficulty catching wind: Because it is totally dependent on wind and air currents, it is possible that an unfavorable climate will compromise production;
Visual Impact: The installation of wind turbines can cause major changes in the landscape, either due to the space required to install the equipment or the size of the necessary mechanisms;
Animal Impact: Modifications related to the installation of wind energy equipment change the habitat of several animals, especially migratory birds, so that they have to adapt;
Sound impact: Wind energy production is very noisy, which can frighten animals and disrupt the daily lives of people living in areas near the wind farm.

There might not be ample enough wind to power all the electricity in the United States and in some places there might not be wind at all so people wouldn't be able to have electricity.
