You can know which one has more thermal energy by testing the temperature, if it is warmer the more energy it has because the particles are going faster than they would if it was cold. because, when its cold the particles slow down until they are so cold they are frozen. (ice).
Answer:
None of the options are correct.
Explanation:
1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.
2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.
3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.
When the balanced reaction equation of methane combustion is:
CH4 + 2O2 →CO2 + 2H2O
so, we can see that each 1 mole of methane combusted will give 2 moles of water as a product.
so first, we need to get the moles of methane =
= mass of methane /molar mass of methane
= 52.6 g / 16.04 g/mol
= 3.28 moles
when 1 mol of methane produces→ 2 moles of water
∴ 3.28 moles methane produces → X moles of water
∴ moles of water = 3.28 * 2
= 6.56 moles
when each 1 mole of water has 6.02 x 10^23 (Avogadro's number ) individual molecules:
∴number of molecules of water = 6.56 * 6.02 x 10^23
= 3.9 x 10^24 molecules
1. The bird has to adjust where it doves in for the fish because the light is refracted by the water, making it look like the fish is in a different position than it is.
2. The clock is reflected in the mirror, which sends each part of the image straight back.
4. Your first part is correct. The second part: The plant would look dark brown or black and red light. Red light has no green wavelengths to reflect, and the red light would be absorbed by the leaf, making it appear almost black.
LMK if you have questions.
