Cars, aeroplanes, factories etc
<span>A polymer forms because the hydrocarbon joins with itself in a polymerization reaction.
I really hope this helps! :D</span>
Answer:
Solubilities of 
increases with increasing acidity
Explanation:
Concentration of 
decreases with increasing acidity. Therefore solubility of 
increases to keep constant solubility product.
Concentration of 
decreases with increasing acidity due to formation of 
. therefore solubility of ZnS increases to keep constant solubility product
Increasing acidity have no effect on this above equilibrium. Therefore solubility of 
remains constant.
Concentration of 
decreases with increasing acidity due to formation of 
. Therefore solubility of 
increases to keep constant solubility product.
Increasing acidity have no effect on this above equilibrium. Therefore solubility of NaI remains constant.
Concentration of 
decreases with increasing acidity due to formation of 
. Therefore solubility of 
increases to keep constant solubility product.
Answer:
38 canisters
Explanation:
The combustion of propane can be represented by the equation below:
C₃H₈ (g) + O₂ (g) → CO₂ (g) + H₂O(g) ΔHc = -103.85 kJ/mol
The boiling of water is represented below:
H₂O(l) → H₂O(g) ΔH = Q = mcΔT
The heat necessary to make water reach the boiling point is Q, which is calculated with the mass of water (m = 4.0 kg), its specif heat capacity ( c = 4.200 J/kg°C) and temperature variation (ΔT = 100 - 25)
Therefore, ΔH = Q = 4.0 kg x 4.200 kJ/kg°C x 75 °C
ΔH = Q = 1260.0 kJ
This is the amount of heat necessary to heat the water every day. Since the expedition will last 7 days, the total heat will be 8820 kJ
Now we need to calculate the amount of propane needed to generate this heat:
1 mol C₃H₈ _______ 103.85 kJ
X _______ 8820 kJ
x = 84.9 mol C₃H₈
1 mol C₃H₈ _____ 44 g
84.9 mol C₃H₈ ___ x
x = 3735.6 g
1 canister _____ 100 g C₃H₈
x _____ 3735.6 g
x = 37.3 canisters
The minimum number of fuel canisters I must bring is 38 canisters.
