Answer:Macaya (floruit 1802), was a Kongolese-born Haitian revolutionary military leader. Macaya was one of the first black rebel leaders in Saint-Domingue to ally himself with the French Republican commissioners Sonthonax and Polverel. He helped to lead forces that recaptured Cap-Français on behalf of the French Republicans.
Macaya was born in west-central Africa, probably in the Kingdom of Kongo, and taken to the French colony of Saint-Domingue as a slave. After the outbreak of the 1791 slave rebellion in northern Saint-Domingue, Macaya became a lieutenant of an elderly rebel commander named Pierrot. Pierrot's rebel forces were based in the hills outside of Le Cap (Cap Francaise), near Bréda plantation by 1793.
Explanation:
In order for the human being stomach to digest food, it uses hydrochloric acid (HCl). This is a very effective an dstrong acid that can burn the lining of the stomach and even cause ulcer if this lining does not contain enough mucus.
Back on track, a reaction between an acid and a base usually yields a salt and water. The two bases that we will use in the reaction with HCl are Mg(OH)2 and CaCO3 (note that (OH)- and (CO3)- both define basis)
MAKE SURE TO BALANCE YOU EQUATION, WHERE THE NUMBER OF MOLECULES ENTERING SHOULD BE EQUAL TO THE NUMBER OF MOLECULES RESULTING.
Equation #1:
<span>2HCl + Mg(OH)2 --> 2H2O + MgCl2
MgCl2 is the salt
</span>Equation#2:
<span>2HCl + CaCO3 --> H2O + CO2 + CaCl2</span>
CaCl2 is the salt
Carbon dioxide is formed as a result of the additional carbon carbon, the reaction ideally outputs H2CO3 which is a very weak base the breaks into water and CO2

Explanation:
4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)
Ci(NH₃) = 3.5mole/4L = 0.875M
Cf(NH₃) = 1.6mole/4L = 0.400M
Rate-1 => Δ[NH₃]/Δt = |(0.400M - 0.875M)/3min| = 0.158M/s
Rate-2 => 6(Δ[NH₃]/Δt) = 4(Δ[H₂O]/Δt) => 6/4(0.158M/s) = 0.237M/s
Rate-3 => 5(Δ[NH₃]/Δt) = 4(Δ[O₂]/Δt) => 5/4(0.158M/s) = 0.237M/s
_________________________________________________________
NOTE: When setting up comparative rate expressions for a given reaction, set the rates expressions as equal then swap coefficient values. Then solve for rate of interest and substitute givens.
example: for NH₃ and H₂O
- set rates expressions equal => Δ[NH₃]/Δt = Δ[H₂O]/Δt
- then swap and insert coefficients from given rxn ...
- solve for rate of interest ...
4NH₃(g) + 5O₂(g) => 4NO(g) + 6H₂O(g)
=> 6(Δ[NH₃]/Δt) = 4(Δ[H₂O]/Δt)
=> Δ[H₂O]/Δt = 6/4(Δ[NH₃]/Δt) = 6/4(0.237M/s) = 0.237M/s
