Convert 4.0 moles of krypton into liters of krypton.
Answer:
4.0 moles of krypton converts to 89.6L.
Explanation:
To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.
We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

Which statement is correct?
(1 point)
The solution has the same concentrations of nitrogen gas and ammonia.
The solution has the same concentrations of nitrogen gas and ammonia.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
The solution has the same concentrations of nitrogen and hydrogen gases.
The solution has the same concentrations of nitrogen and hydrogen gases.
Both directions of the reaction have stopped.
Both directions of the reaction have stopped.
Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.
So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.
In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

can the following alcohol be prepared as a single product by hydroboration-oxidation of an alkene? can it be prepared as a single product by the acid-catalyzed addition of h2o to an alkene? select the single best answer.
Answer:
Yes both methods give a single product.
Explanation:
The answer can be Yes, both the methods will yield a single product. The correct option is D.
What is alcohol formation?Alcohols can be made by hydrating alkenes or reducing aldehydes, ketones, acids, and esters. Water elements can be added to an alkene's doublebonded carbons in either a Markovnikov's or an antiMarkovnikov's manner.
When yeast ferments the sugars in grains, fruits, and vegetables, it produces it. For example, wine is made from grape sugar, and vodka is made from potato sugar.
In the presence of a catalyst, lower molecular weight olefins react with carbon monoxide and hydrogen in a reaction known as hydroformylation or the oxo reaction. The resulting aldehyde is then hydrogenated to produce alcohol.
Thus, the correct option is D.

An highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity. D. A soft, sensitive, and lustrous element with the highest conductivity of any element. Please select the best answer from the choices provided A B C D.
Answer:
c.
an highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity.
Explanation:
A precious metal is a highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity, hence option C is correct.
How precious metal is differed from the base metal?Rare metallic chemical elements with a high economic value are known as precious metals. The valuable metals are often less reactive chemically than most elements.
Iron-free metals and alloys are not considered base metals. Base metals have a propensity to tarnish, oxidize, or corrode with time or when exposed to the environment, in contrast to valuable metals.
Base metals typically cost less than precious metals since they are more plentiful in nature and sometimes easier to mine.
Therefore, a precious metal is a highly valuable element with super and electric and thermal conductivity, high luster, and sensitivity.

What was the effect of decreasing the copper's mass?
Answer:
Decreasing the temperature of the copper made the final temperature decrease.
Heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.
What is heat?The transfer of kinetic energy from an energy source to a medium, an object, or from one to the other is referred to as the creation of heat. The sun is the source of all energies. It is the natural source of solar energy, heat, and light. Thermal energy can move through three different channels: conduction, convection, and radiation.
Therefore, the increase in temperature is always proportionate to the mass of water. Thus, the final temperature will be lower if we increase the water mass. The temperature will be lower in the end. The density reduces as volume grows. Consequently, density drops as temperature rises.
Thus, heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.
