Answer:

The oxygen will occupied 84.7 L.

Explanation:

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:  

P*V = n*R*T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

In this case:

Replacing:

768 mmHg* V= 3.5 mol* 62.36 [tex]\frac{mmHg*L}{mol*K}[/tex] *298 K

Solving:

[tex]V=\frac{3.5 mol*62.36\frac{mmHg*L}{mol*K}*298 K }{768 mmHg}[/tex]

V= 84.7 L

The oxygen will occupied 84.7 L.

Answer:

Atomic orbital

Explanation:

Electrons are found around the atomic nucleus in three-dimensional regions.

The energy levels they are in can be named according to a numbering order such as 1, 2, 3, 4, ..., increasing in proportion to the distance to the nucleus. Each of these energy levels can be divided into sublevels s, p, d, f which are also called orbitals.

adding all mass i hope you got

Answer:

[A]²

Explanation:

Since the formation is independent of D, D is 0 order.

Since a quadruples when it is doubled it can be written as

2A^X= 4

To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4

so the unknown power is 2

Making the rate law

[a]²[b]⁰

or simply just

[A]²

Answer:

During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel, glucose and other sugars for building plant structures. This process forms the foundation of the fast carbon cycle.In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.

Answer:

During photosynthesis, plants also absorb carbon dioxide and sunlight to create fuel, glucose, and other sugars for building plant structures. This process forms the foundation of the fast carbon cycle.

Answer:

4400, and 0

Explanation:

since they traveled 2200 in one direction, to return home they must travel that distance again, so they travel 4400

displacement is the distance from the start point, so since they are back home at the end of the trip, they did not get displaced at all

if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest

Answer:

My answer to the question is 4400 and 0

B is talking about the bees helping the flowers, so that isn't helping the bees but the flowers instead

Answer:

Once the sun comes up, the sunlight excites the cold air in the first foot or so above the ground (which can be 10 or more degrees colder), which causes it to move around and mix into the next several feet of air. That “mixing upward” drops the temperature of the air at thermometer level.

Answer:

Energy is released because the temperature of the surroundings increases.

Explanation:

"Energy is released because the temperature of the surroundings increases" is true because when the temperature of the hot pack increases, that means that energy (heat/thermal) is being released.

"Energy is taken in because the temperature of the surroundings increases" is false because energy is actually being released in this chemical reaction.

"Energy is taken in because all chemical reactions take in energy" is false because energy is being released in this reaction and not all chemical reactions absorb energy.

"Energy is released because all chemical reactions release energy" is false because not all chemical reactions release energy.

Answer:

Explanation:

Answer: Solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.

Explanation:

A process in which solid substance converts directly into gas without undergoing liquid state is called sublimation.

For example, when solid ammonium chloride is heat in the apparatus then it will convert directly into vapors without undergoing liquid state. During this process it leaves behind anhydrous chloride into the mixture itself.

When these vapors are cooled down at the surface of funnel then it gives ammonium chloride in the solid state.

Thus, we can conclude that solid ammonium chloride can be separated from a solid mixture of ammonium chloride and anhydrous chloride through the process of sublimation.

Answer:

64.5g

Explanation:

First you add the mass of reactant 1 and reactant 2, then you simply subtract the amount of gas released from your answer, and that would be the total mass of ALL the products formed.

My work:

13.6g + 72.9 = 86.5g

86.5g - 22g = 64.5g

I'm pretty sure it's B :)
