Answer:
1. D. Weathering by the actions of plants
2. C. Mechanical Weathering
3. A. Weathering by the actions of animals
4. B. Chemical Weathering
The chemical reaction shows the change that took place in the reaction. The number of moles of LiOH reacted is 1.16 moles.
<h3>What is chemical reaction?</h3>
The term chemical reaction has to do with the combination of two substances to yiled a new one that is different from each of the reactants. From this reaction;
.
Number of moles of CO2 = 25.5 g/44 g/mol = 0.58 moles
Since 1 mole of CO2 reacts with 2 moles of LiOH
0.58 moles reacts with 0.58 moles * 2 moles/ 1 mole
= 1.16 moles

Answer:
e. 4.1 x 10^−4
Explanation:
For the reaction;
2N2O5(g) → 4NO2(g) + O2(g)
The rate of formation is given as;
(1 / 4) Δ [O2] / Δt = (1 / 2 )Δ [N2O5] / Δt
Δ [O2] / Δt = 8.1 x 10^−4 M/s
Inserting into he equation, we have;
(1/4) (8.1 x 10^−4 ) = (1/2) (Δ [N2O5] / Δt)
2.025 x 10^−4 = (1/2) (Δ [N2O5] / Δt)
Δ [N2O5] / Δt = 2 * 2.025 x 10^−4
Δ [N2O5] / Δt = 4.1 x 10^−4
Correct option is option E.
