The process of photosynthesis in plants releases oxygen into the atmosphere. Respiration by plants and animals, as they use the energy stored in food, and the process of decomposition of dead organisms, releases carbon dioxide into the atmosphere. All three work together to maintain the carbon dioxide-oxygen cycle.
When a molecule is going through any physical change, solid to liquid or liquid to gas, as it changes, the temperature remains constant. it does not increase or decrease, it stays at that temperature/.
For example, water evaporates/ boils at 100 C. if you are heating water to the point of boiling, it will remain 100 C until all the water evaporates. Once it becomes a gas, the temperature will continue to increase
Answer: When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Explanation: Hope this helps!!
3.50g H2:
3.50g H2 x 1 mol H2 / 2(1.01gH2)= 1.7675mol H2
- the grams cancel out
- the answer rounded up would be: 2 mol H2
