one liter of gas has a pressure of 150.00kPa at 25 degrees celcius. if the pressure increases to 600.kPa and the temperature to 100.0 degrees celcius, what would be the new volume of the gas

Answers

Answer:

0.313 liters

Explanation:

You want to use the Combined Gas Law Equation: (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). You then want to cross off things that don't change, so moles(n) in this example. Then convert the temperature to Kelvin (always), and solve algebraically.

Answers

Hot spot volcano is the type of volcano which is formed at a weak spot in

the middle of a plate.

Hot spot volcano is an area in the Earth crust which is characterized by large

amount of heat flow in the area due to the volcanic activity. Hot spot  

volcano is formed at the middle of the plate as against junctures in which

other types are formed.

The weak spot is what gives rise to the unusual heat flow which makes hot

spot volcano most appropriate.

Paper chromatography is a method used to distinguish or separate coloured substance mixtures.

In the image, take an example of colured chemical placed in a glass beaker. If a paper is placed in that chemical, coloured spots are separated and displayed on the chromatogram.

It was founded in 1944 A.D by a scientist called Erwin Cargaff.

What products are obtained by the electrolysis of CuSO4 solution using copper electrode ? Show with help of chemical reaction.​

Answers

Answer: The products will be copper and oxygen.

Explanation: Copper electorde is an active electrode so it constantly takes part in the electrolysis. Cathode is a pure copper negative electrode and anode is a impure copper positive electrode. So the copper present in the solution, along with the copper present in the anode will come off and go to the cathode. As a result, cathode gains copper. And the remaining impurities settle down in the bottom.

In the anode, oxygen will be given off because according to the order of discharge, if SO4 is present then the ions will stay in the solution and oxygen will be released. So at the end, solution of SO4 and H2O will be remaining while copper and oxygen is extracted.

The half equations are-

Cathode: Cu2+ + 2e- = Cu

Anode: Cu + 2e- = Cu2+

Something you might not know: The solution in electrolysis turns blue when copper goes to the cathode. So copper electrodes are also used in electroplating.

2. Predict solutions for slowing the loss of biodiversity.



3. Describe three ways humans are contributing to the loss of biodiversity.





4. How does the introduction of invasive, non-native species, threaten biodiversity?

Answers

Answer:

1.

Rainforests are important due to the amount of oxygen the tree's produce. It also adds biodiversity and more balance in the food chain of animals.

2.

If we slowed transportation and agricultural farming, greenhouse gases and carbon monoxide would be reduced magnificently.

3.

One way is that Humans are supplying demand for animal agriculture for food (when not need to). The greenhouse gases created by the factories alone are creating much of the ozone's destruction. Also, another reaction to demand of meat is, The space needed for farmland. They burn down much of the rainforest for farmland and grass for the cows and other animals. Thirdly, traveling alone and having many household luxuries aren't helping either. Lowering the use of composite resources and more wind, solar, and water energy can help the earth in total.

4.

Introducing invasive species endangers many of the other species. They could have a advantage or disadvantage over the other species. causing either over, or under, population for many of the species. Throwing the balance of it all off.

What is the hydronium ion concentration of a solution with a POH of 6.90?
O 6.29 x 10-7 M
6.53 x 10-7 M.
O 7.18 x 10-8 M
O 7.94 x 10-8 M

Answers

Answer:

O 7.94 x 10-8 M

Explanation:

Did the test

The hydronium ion concentration of a solution with a pOH of 6.90 is 7.94 × 10⁻⁸ M.

What is the relation between pH & pOH?

Relation between the pH and pOH will be represented by the below equation as:

pH + pOH = 14

Given that pOH = 6.90

So, pH = 14 - 6.90 = 7.1

Also we know that, pH = -log[H⁺]

[H⁺] = [tex]10^{-pH}[/tex]

[H⁺] = [tex]10^{-7.1}[/tex]M

[H⁺] = 7.94 × 10⁻⁸ M

Hence the concentration of hydronium ion is [tex]10^{-7.1}[/tex] M.

Neutral atoms get smaller as you move across the periodic table from (left to right) because the atom increases in electrons. The more electrons, the bigger the effective nuclear charge (electron and proton attraction) and so basically the atom shrinks.

Which gas makes your voice deeper or has the opposite effect on you than helium when you inhale it.

Answers

The correct answer is Sulfur Hexafluoride
it’s an inert gas that is known to be six times heavier than the air we breathe. While Helium being lighter makes our voice higher, SF6 makes our voice deeper. The sound travels slower in denser gases which is why our voice will come out deeper and rather slow.

Answer:

Sulfur hexafluoride

Explanation:

It is heavier than air that we breathe so it has an opposite effect.
