Opposite the ordinal<span> equation, the reaction </span>can<span> become </span>energy-absorbing<span>,
N2 (g) + </span>four liquid<span> (l) ---> </span>a pair of<span> NO2 (g) + </span>four<span> H2 (g),
delta H = 212.5 kJ/mol </span>a pair of<span> NH3 (g) ----------------> N2 (g) + </span>three<span> H2 (g)
delta H = </span>100<span> and fifteen kJ/mol </span>transfer<span> those </span>a pair of<span> equations at </span>constant<span> time.
You get the equation </span>needed and also the succeeding<span> delta H </span>is that the total<span> of the </span>several<span>
delta H: 4H2O (l) + 2NH3 (g) ------> 2NO2 (g) + 7H2 (g) , delta H = 327.5 kJ/mo</span>
Answer: Gemstones of various minerals are highly prized for beauty, durability, and rarity. Some noncrystalline materials of organic origin. Examples are pearl, red coral, and amber also are classified as gemstones. Gemstones have attracted people since the ancient times, and have been used for jewelry.
Explanation:
Answer:
macroevolution
Explanation:
Macroevolution is said to be the evolutionary changes that occur on a larger scale beyond a single species as a result of evolutionary forces such as mutation, gene flow, genetic drift. Macroevolution, unlike microevolution, usually results into the emergence of two new species with pronounced changes. The event as illustrated in the question is an example of macroevolution.
The Earth was first considered habitable when we discovered that it was Microbial organisms that started the process. I would go with D.
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life.
Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm.
The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size.
The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.
