A flask filled with oxygen is heated from 5 degrees Celsius to 30 degrees Celsius. The starting pressure was 50 kPa, what is the

final pressure? (Be sure to convert from Celsius to Kelvin, add 273 to your Celsius temperature to get the temperature to kelvin. Ex. 0 degrees Celsius id equal to 273 kelvin)

54.5kPa

Explanation:

Given parameters:

T₂ = 30°C = 30+273 = 303K

T₁ =  5°C = 5+273 = 278K

P₁ = 50kPa

Unknown:

P₂ = ?

Solution:

We can solve this problem using the combined gas law simplification and assuming that volume is constant as seen from the container:

            \frac{P_{1} }{T_{1} } =  \frac{P_{2} }{T_{2} }

Making the unknown the subject of the formula:

            P₂ = \frac{P_{1} T_{2} }{T_{1} }

             P₂ = \frac{50 x 303}{278} = 54.5kPa

Atoms have been traditionally viewed as being composed of three different types of particles: protons, neutrons, and electrons.
sattari [20]

Answer:

See explanation

Explanation:

Before the advent of the wave-particle duality theory proposed by Louis de Broglie, there was a sharp distinction between mater and waves.

However, Louis de Broglie introduced the idea that mater could display wave-like properties.  Erwin Schrödinger developed this idea into what is now known as the wave mechanical model of the atom.

In this model, electrons are regarded as waves. We can only determine the probability of finding the electron within certain high probability regions within the atom called orbitals.

This idea has been the longest surviving atomic model and has greatly increased our understanding of atoms.

Match the following chemical reactions:
S_A_V [24]

Answer:

Synthesis - 4

reversible- 2

exchange- 1

decomposition-3

Explanation:

In synthesis reaction two or more components combines to form a single product. example 2H2+O2⇒2H2O

In reversible reaction two reactants combine to form two products . The products then reacts and forms back the reactants. example N2 +3H2 ⇒2NH3

In exchange reaction there is an alternation of ions of reactants to form new products. AB+CD ⇒AC + BD

In decomposition reaction, molecules of a compound break down by the action of heat or light or catalyst. example CaCO3 ⇒CaO +CO2

What do ionic compounds form
Snowcat [4.5K]

Answer:

By the result of the formation of positive and negative ions, Ionic compounds are formed.

Explanation:

Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion. The atom which forms a positive ion loses electrons to the atom which gains electrons to form a negative ion. A compound is not stable unless the number of electrons which are lost and gained are equal

In which state of matter is there no particle movement
Alex
Salutations!

In which state of matter is there no particle movement

Solid is the state of matter that has no particle movement. Solid is tightly packed, rigid, and does not takes the shape of the container. The only movement that they have is the vibration movement, otherwise, it is still and has no particle movement.

Hope I helped (:

Have a great day!
