A gas sample occupies 2.1 L at a pressure of 101 kPa.
What volume will it occupy if the pressure is increased to 235 kPa?
A. 4.9 L
B. 1.6L
C. 1.2 L
D. 0.9 L
Answer:
D) 0.9 L
Explanation:
At constant temperature,
PV = Constant
so,
P1.V1 = P2. V2
101 × 2.1 = 235 × V2
V2 = 0.9 L
Answer:
0.9L
Explanation:
Given parameters:
Initial volume = 2.1L
Initial pressure = 101kPa
Final pressure = 235kPa
Unknown:
Final volume = ?
Solution:
The relationship is between pressure and volume. To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P₁ is the initial pressure
V₁ is the initial volume
P₂ is the final pressure
V₂ is the final volume
Now insert the parameters and solve;
2.1 x 100 = 235 x V₂
V₂ = 0.89L

Answer:
maybe "A" but I'm not sure
Light can be treated like a particle becuase it comes in chunks of energy called photons.
Particle nature of lightLight exists in dual form, as wave and particle. Light can exist as a wave becuase it transfer energy from one point to another.
Light can also exist as particle becuase it consists of packs of energy known photons.
Thus, we can conclude that, light can be treated like a particle becuase it comes in chunks of energy called photons.

Explanation:
which period of the periodic table is completely made up of elements with no known stable ions?
Answer:
I think the answer is period 7
Explanation:
The period in periodic table, in which no stable ions of elements exists is 7th period. They contains actinides.
What are actinides?Actinides are 7th period elements classified to F block of periodic table. A periodic table contains vertical columns called groups and horizontal rows called periods. Each elements are classified into suitable groups based on their similarity in properties with other group elements.
There are four blocks in periodic table which are s, p, d and f block. S block elements are metals and d block contains transition metals and p block have non metals including gases and metalloids.
Actinides are f- block metals. All the elements in the period are radioactive. That's why they don't have a stable isotope or ion. They continuously undergo radioactive decay by the emission of charged particles.
Hence, the period containing unstable elements is 7th one.
