Thermodynamically favored process are those processes that do not require any assistance from outside the system e.g water boils at 25 degrees. Thermodynamically unfavored processes require assistance from outside to induce the required change for example water doesn't freeze at 15 degrees and therefore for that to happen several factors in the system have to be modified to achieve this. Therefore, there is a possibility of companies to produce product by using thermodynamically unfavored process by inducing changes in the system to achieve desired change or modification.
Answer: For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. Burning lithium metal produces lithium oxide. Lithium oxide is produced by the thermal decomposition of lithium peroxide at 300-400°C.
Answer:
d.
Explanation:
i was think b at first but that doesnt really explain how it gets to the circulatory system so d because without the the regulation of the heart rate and oxgen rich blood the muscular system can do absolutely nothing

Answer:
D 1.0 g of powdered Zn(s) in 50. mL of 1.0 M HCl(aq) at 30.°C
Explanation:
There are several factors affecting and controlling the rate of chemical reactions.
Some of which are applicable in resolving this problem is the nature of the reactants and their concentration. Also, the temperature of the reaction is also very important.
- Reactants that powdered ensures a faster rate because, more surface area is exposed for the reaction.
- Also, the higher the temperature, the faster the reaction will take place.
- So, the powdered zinc and the higher temperature reaction will facilitate a better rate of reaction.
