Answer:
a. It turns color in the presence of an enzyme that us bound to the secondary antibody.
Explanation:
The compound chloronapthenel is used in the reaction because it changes the color in the presence of an enzyme. It is strong organic compound which is used in biochemical processes.
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.
Answer:
Heat of solution= - 63KJ/mole
Heat evolved = - 18.82KJ
Explanation:Heat of solution = Heat of solute + Heat of hydration
◇Hsoln = - ( - 7.3 × 10 ^ 2) + ( - 793 ) KJ / mol
◇H soln= - 63 KJ
Use enthalpy of solution equation to determine the enthalpy of solution for LiI
LiI ---> Li^ + + I^-
Molecular mass of LiI=133.85g
The chemical equation for the dissociation will be:
40gLiI (1molLiI)/133.85g LiI - 63KJ/1 mol LiI
18.82KJ
The heat was evolved because the value of enthalpy was negative
