How you guess that the pH of water is low?
Maybe the water has some CO2 dissolved in it.
What happens to water vapor concentration when carbon dioxide increases?
Co2 is a acidic gas. water turn acidic when CO2 dissolved.
Does crystallisation increase or decrease entropy?
Entropy is the tendency of the universe to become more disorganized. Photosynthesis decreases entropy because it takes a larger number of reactants and converts them into a more organized form of energy, where there are less products than reactants. 6 H2O + 6 CO2 ---> C6H12O6 + 6 O2
Is oxygen a gas dissolved in sea water?
Oxygen does dissolve into sea water, as do many other gasses such as CO2.
Which dissolved gas is present in the ocean much greater proportion than in the atmosphere?
The amount of carbon dioxide in the atmosphere is very small (.04%) because CO2 is in great demand by photosynthetic plants as a source of carbon for growth. The proportion of dissolved CO2 in water is about 15% of all dissolved gases. There is about 60 times more CO2 dissolved in the ocean as in the atmosphere.
Is CO2 are solute?
Carbon dioxide is a solute if it is dissolved in water.
How you guess that the pH of water is low?
Maybe the water has some CO2 dissolved in it.
What is CO2 dissolved in H2O?
Carbon dioxide dissolved in water can be considered as an acid - carbonic acid, H2CO3.
What would represent an increase in entropy?
A change of state from solid to liquid, or liquid to gas, or directly solid to gas., all indicate an increase in entropy. Also an increase in moles from reactants to products. The Classic example being the thermal decomposition of calcium carbonate CaCO3(s) ==Heat==> CaO(s) + CO2(g) You have a gas liberated from a solid, so an increase in entropy. You also have one mole reactant increasing to two moles of product, so again an increase in entropy.

What are CO2 bubbles?
Carbon dioxide gas bubbles dissolved in water.
Under what condition can entropy decrease in a system?
First of all, entropy is the defined as the extent to which something is disordered. In chemistry, for entropy in a SYSTEM to decrease, the products of a reaction must be less disordered than the reactants. The extent of "disordered-ness" can be seen by the physical states of the substances. A gas is more disordered than a liquid, which is more disordered than a solid. So, an example of a reaction that leads to a decrease in entropy is: HCl(gas) +NH3(gas) -----> NH4Cl(solid) So you see, there are more gaseous molecules in the reactant side of the equation than in the product side, which means the products are less disordered than the reactants. ----------------------------------------------- However, one must note that if the entropy of a system(reaction) decreases, the entropy of the surroundings should increase. This is because change in TOTAL entropy(A) = change in entropy of SYSTEM(B) + change in entropy of SURROUNDINGS(C). It is a rule that A must increase in every case ( have a positive value). If the B is negative(a decrease in entropy), C must be positive(an increase in entropy) to keep the value of A positive.
Amount of CO2 dissolved in different softdrinks?
AMOUNT OF CO2 DISSOLVED IN SOFTDRINKS?
What do you add to carbonate a drink?
Carbon Dioxide, or CO2, is dissolved in water to carbonate it. A "seltzer bottle" uses a CO2 cylinder to make carbonated water from tap water.
Is oxygen a gas dissolved in sea water?
Oxygen does dissolve into sea water, as do many other gasses such as CO2.
Carbonic acid forms when carbon dioxide is?
Dissolved in water, e/g/ atmospheric CO2 into rain-water.
