2Fe(s) + 3Cl₂(g) →2FeCl₃(s)

mol Fe = 15.52 : 56 g/mol = 0.277

mol FeCl₃ = mol Fe = 0.277 (same coefficient)

mass FeCl₃ = 0.277 x 162.2 g/mol = 44.93 g

% yield = 34.5 : 44.93 = 76.79 %

What type of rock commonly often contains gas bubbles and the mineral(s) hornblende, muscovite, olivine, lucite, and/or plagiocl

olga_2 [115]

Scoria

Explanation:

Scoria is a rock that is commonly made up of gas bubbles and minerals such as hornblende, muscovite, olivine, lucite and or plagioclase.

Scoria is an extrusive igneous rock with a lot of cavities and vesicles indicating gas bubbles.

Scoria is product of basaltic magma.
It has nearly the same composition as basalt since it originates from it.
They silica deficient and very fine grained with holes in them.
The holes shows channels by which trapped gases are forcefully ejected out.
They are usually found associated with cindercone volcanoes.

Below is a proposed mechanism for the decomposition of H2O2. H2O2 + I– → H2O + IO– slow H2O2 + IO– → H2O + O2 + I– fast Which of

Savatey [412]

Answer: Option (d) is the correct answer.

Explanation:

The given equations as as follows.

$H_{2}O_{2} + I^{-} \rightarrow H_{2}O + IO^{-}$ (slow)

$H_{2}O_{2} + IO^{-} \rightarrow H_{2}O + O_{2} + I^{-}$

Therefore, overall reaction equation will be as follows.

$2H_{2}O_{2} + I^{-} + IO^{-} \rightarrow 2H_{2}O + O_{2} + IO^{-} + I^{-}$

So, cancelling the spectator ions then the equation will be as follows.

$H_{2}O_{2} \rightarrow 2H_{2}O + O_{2}$

As, it is known that slow step of a reaction is the rate determining step. Therefore, rate law for the slow step will be as follows.

$H_{2}O_{2} + I^{-} \rightarrow H_{2}O + IO^{-}$

Rate law = $k[H_{2}O_{2}][I^{-}]$

Hence, the reaction is first order with respect to $[I^{-}]$ and it is also first order reaction with respect to $[H_{2}O_{2}]$ .

Also, $[I^{-}]$ acts as a catalyst in the reaction.

Thus, we can conclude that the incorrect statement is $IO^{-}$ is a catalyst.
