What is a nonpolar bond?
Answer:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecul
Explanation:
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
What is the complementary DNA sequence to A-T-T-G-C-A?
Answer:
T-A-A-C-G-A or just TAACGA
Explanation:
A=T
G=C
C=G
T=A
This is the answer key to all complementary DNA strands.
Hope this helps you out.
I wont graduate. Why can light be treated like a particle?
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.
