Answer:
The sand bath spreads the heat out so that the flask is heated evenly. This reduces the chance of the flask breaking and ensures that there are no hot spots in the reaction mixture which could lead to excessive charring,
Explanation:
Answer:
Answer for the given statements: (1) T , (2) F , (3) T , (4) F , (5) F
Explanation:
At the given interval, concentration of HI = 
Concentration of
= 
Concentration of
= 
Reaction quotient,
, for this reaction =
species inside third bracket represents concentrations at the given interval.
So, 
So, the reaction is not at equilibrium.
As
therefore reaction must run in reverse direction to reduce
and make it equal to
. That means HI(g) must be produced and
must be consumed.
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.
The reaction for this problem is:
H₂ + Cl₂ → 2 HCl
1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.
You're going to divide the mass of chlorine within the compound by the mass of the compound, and then multiply the result by 100 to get the answer
