Answer:
A pH value of 3
Explanation:
The pH scale has 14 numbers:
- 7 is a true natural
-anything above 7 is a base
-and anything under 7 is an acid
pH of three is a strong acid
Answer:b. gravitational, kinetic, thermal
Explanation:
The above explains the mechanism of the core forming process on earth/planet.
It is believed that this process might has contributed significantly to a planet's early stages heating. The time when these core-forming event happened is thought to have been mainly completed very early when Earth was young . The type of this event rather than it being seen as a single catastrophic event, it is likely to have been as a result of contractions on the earth severally.
The addition of partially differentiated material from another giant impact the rate of this spasm , and it increases each time the planet's mass is to increased.
This is a little on the history of planetary evolution.
Answer:
This question appear incomplete
Explanation:
This question appear incomplete. However, fuel is formed through a natural phenomenon involving the conversion of large amount dead and decayed organisms (usually algae and zooplanktons) to combustible fuel through exposure to relatively high temperature and pressure (over millions of years) in the earth's crust. Thus, since this involves a sort of absorption of heat energy (from the earth's crust), it can be referred to be an endothermic reaction.
Answer:
The second answer, because when something saturated, it has the maximum possible number of hydrogen atoms.
It is a covalant bond. Because any compound made up of nonmetals will be covalant. Compounds made up of a non metal and metal willl form a ionic compund. :)
