Answer: AIBN is good radical initiator
Explanation:
A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.
Question
Which one is more dangerous Ac or Dc how is it?
Answer
AC

AC has the voltage alternates, it enter and exit from your body without a closed loop.
Answer:
The two blocks have the same temperature
Explanation:
Given;
heat capacity of Aluminum = 0.9 J/g
heat capacity of copper = 0.35 J/g
thermal conductivity of copper = 385 W/(K m)
thermal conductivity of Aluminum = 205 W/(K m)
Based on the given data, it can be concluded that;
- Aluminum’s higher heat capacity means it does not get as hot when energy is shared between the two blocks, so the copper will be hotter
- Copper’s higher thermal conductivity will cause the aluminum to heat up compared to the copper
However, the two metallic blocks (aluminum block and a copper block), were allowed to achieve thermodynamic equilibrium, and as a result they will have the same temperature.
Therefore, the correct statement is "The two blocks have the same temperature".
Hey there!
Find molar mass of C₆H₂Cl₄.
C: 6 x 12.01
H: 2 x 1.008
Cl: 4 x 35.45
------------------
215.876g
This is the mass of 1 mole of C₆H₂Cl₄.
Multiply 215.876 by 5.99.
215.876 x 5.99 = 1293
The mass of 5.99 moles of C₆H₂Cl₄ is 1293 grams.
Hope this helps!
Answer:
Option D
Oxygen particles mix evenly with hydrogen particles.
Explanation:
Diffusion refers to the movement of gasses from a region of higher concentration to a region of lower concentration.
Diffusion occurs in gases because their particles are in a state of constant random motion.
Due to this continuous random motion, once the oxygen and the hydrogen are added to the container, they will begin to mix freely with each other until they fill up the entire volume of the container.
