Answer is: C. exothermic reactions.

For example, the Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃) and energy is released:

N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.

There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).

Where would the temperature of the ocean's surface water be the lowest?
bazaltina [42]

Answer:

The correct answer is option C, areas with a high salinity

Explanation:

The higher the density of the ocean water, the lower will be the temperature. The highly saline ocean water thus exists in the polar regions than the tropic regions. Due to high density the cold water seeps down and thus it further becomes cooler while a low density ocean water remains at the surface and possess additional heat

When does star formation begin?
arlik [135]

Answer: Star formation begins when the denser parts of the cloud core collapse under their own weight/gravity. These cores typically have masses around 104 solar masses in the form of gas and dust. The cores are denser than the outer cloud, so they collapse first.

Hope this helped! :))

Zarrin [17]
Actually you have now a roport of 4:96 water to acid . All you have to do is add water to bring the raport to 37 acid and 63 water.
You need to have 0.5L mixture so
you have to have 18.5acid and the rest water 31.5
so for 18.5 acid you need to add 192.7 ml 96% acid and the rest water
