It's the last answer. The gas-filled sacs allow for it to float, which means it's closer to the surface where the sun is. The top of the kelp collects the nutrients it needs from the sunlight and transfers it throughout the rest of it. Hope this helped!
The pH of the resulting solution is 2.82.
<h3>What is pH ?</h3>
pH is the measure of acidity and alkalinity of a solution , It has a range of 1 to 14.
HCl + NaOH → NaCl + H₂O
0.0040 .0025 0 0
0.0040 -0.0025 0 0.0025 0.0025
Moles of HCl = 0.0015
As 0.0025 moles of NaOH reacts with 0.0025 moles of HCl leaving behind 0.0015 moles of HCl
Concentration of HCl = 0.0015/ 1 = 0.0015 M
[ H⁺] = 0.0015 M
pH = -log [ H⁺]
pH = -log [ 0.0015]
pH = 2.82
Therefore the pH of the resulting solution is 2.82.

Answer:
CH₄ + 2O₂ → CO₂ + 2H₂O
Explanation:
This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.
Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.
Note: in writing chemical equations, the state of matter must always be included.
Reactants : Methane gas CH₄
Oxygen gas O₂
Product: Carbon dioxide CO₂
Water vapor H₂O
CH₄ + 2O₂ → CO₂ + 2H₂O
