You may tell when a solution os formed when the item or particle, such as sugar or salt,
dissolves completely in the solvent, such as water.
Basically, you know when a solution is formed when the material you have placed in the solvent disappears :P
Answer:
89 L
Explanation:
Step 1: Given data
- Initial pressure (P₁): 0.97 atm
- Initial volume (V₁): 105 L
- Initial temperature (T₁): 318 K
- Final pressure (P₂): 1.05 atm
- Final temperature (T₂): 293 K
Step 2: Calculate the final volume of the weather balloon
If we assume that the gas inside the balloon behaves as an ideal gas, we can calculate the final volume of the gas using the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂ / T₁ × P₂
V₂ = 0.97 atm × 105 L × 293 K / 318 K × 1.05 atm = 89 L
Answer: Option (c) is the correct answer.
Explanation:
Photosynthesis is a process in which sunlight, carbon dioxide, and water is used by the plants to make their on food.
Plants absorb energy in the form of heat from the sunlight and thus produce glucose and oxygen from carbon dioxide and water. This absorbed energy is then used to start various chemical and biochemical reactions in the plants.
Hence, photosynthesis is an endothermic reaction.
Thus, we can conclude that a large amount of energy is required to activate the reaction.
The answer C. Why because homogeneous is one thing not two. one of the same thing.
