At what temperature would 2.10 moles of Nitrogen gas have a pressure of 1.25 atm and in a 25.0 L tank? (Hint: R = 0.082 L atm K−1 mol−1)

Don't spam!!!​

I think  depends.......

Answer:

It depends on what medication/drug it is. Pharmaceutical drugs would be a lot before you could "od", some such as "xanax" take a short amount of time.

Answer: C is correct.

Answer:

This is a physical change.

Explanation:

As long as the identity of the substance has not changed, and the element is present before and after, it is a physical change! (Ex: ice melting)

Ok buddy- so if you grab your periodic table there should be numbers on the side... (REFER TOO IMAGE ONE) So then we find them on the periodic table... (REFER TO IMAGE TWO) and if we look at the number the higher it gets the more radioactive it gets, and thats why it stops because the atomic gets so high that the level can't even be able to be mad because it will just explode and when it does that its dangerous because of how radioactive it is... so if we look the more "gas" concentrated elements are seen at the top (i.e. the helium) So the order would be He, C, O, Ne, Ca, I

Then just do that for the rest of them and the numbers on the side are the positive (+) or negative (-) amount of atoms that the atom is missing or ha to be stabilized or over stabilized, but you will learn that later on when you go into periodic equations.

Hopefully this helped, have a wonderful day! :)

Answer:

Is there any answer options?, if not the answer is V2= 43.6m3

"The volume of the gas is calculated Boyles law. If 36.5 m of a gas are collected at a pressure of 755 mm Hg, then the volume of the gas will be 43.6 [tex]m^{3}[/tex]"

What is Boyles Law?

Boyle's law, also known as the Boyle–Mariotte law or Mariotte's law, would be an experimental gas law that specifies that how pressure of a gas decreases as the container capacity increases.

It can be represented by the formula:

[tex][P_{1} V_{1} =P_{2} V_{2}[/tex]

It is given that, [tex]P_{1}[/tex]= 755 mmHg, [tex]P_{2}[/tex] = 632 mm Hg, [tex]V_{1}[/tex]= 36.5[tex]m^{3}[/tex]. [tex]V_{2}[/tex]= ?

Now, put the value of given data in above formula:

[tex]V_{2}[/tex] = 755× 36.5/632= 43.6 [tex]m^{3}[/tex] .

Explanation:

In an ecosystem, a porcupine having sharp gills is  an adaptation that helps protect the animal.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

The volume is 77 L.

Explanation:

where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.

The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).

Answer:

Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power. This is because the resource is always available to be tapped into, unlike with wind or solar energy.

Explanation:

Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Answer:

A geothermal power plant gets energy from the heat deep below the surface of the earth. Shafts are drilled down, often as deep as several kilometres, one to pump water down to the hot rocks, and another nearby which will allow the heated water (or steam) to rise up. This steam is then used to spin electricity turbines to generate electricity.

Answer:

Magnesium oxide

Explanation:

When magnesium reacts with oxygen, the magnesium atoms donate electrons to O2 molecules and thereby reduce the oxygen. Magnesium therefore acts as a reducing agent in this reaction. The O2 molecules, on the other hand, gain electrons from magnesium atoms and thereby oxidize the magnesium.

Answer:

1.3 moles/ 1.33150727 moles

Explanation:

350g x 1 mol/262.86g = 1.3 moles

The molar mass of Mg3(PO4)2 is 262.855 g/mol

Atomic weight of the parts:

Mg 24.3050   x 3 = 72.92

P 30.973762   x2 = 61.95

O 15.9994   x8 = 127.995

There are 262.855 grams in one mole, so  

350.00 g x (262.855g/1 mole) = 1.33 moles Mg3(PO4)2

Answer:

31.96°C

Explanation:

Given that,

Mass of water, m = 100 g

Initial temperature, [tex]T_i=20^{\circ} C[/tex]

The specific heat capacity of water is 4.18 J/(g℃)

We need to find the final temperature of the water if 5000. J of energy is added to the water in the insulated cup.

The heat added to the water is given by :

[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}+T_i=T_f\\\\T_f=\dfrac{5000}{100\times 4.18}+20\\\\T_f=31.96^{\circ} C[/tex]

So, the final temperature is 31.96°C.
