Answer: uranium
Explanation: It’s hard to find when mining and is required for nuclear fission
I would say C. Since the material is getting warmer, the atoms and molecules will start to move fasten and then also create more "messiness" (which is entropy with a less-nice word)
Answer:
Elements are classified into- metals – Nonmetals- Metalloids – Noble gases. State which of A, B, C, D is a:
1) Metallic element
2) Non-metallic element
3) Metalloid
4) Noble gas.
A) Is non-malleable, non-ductile and a poor conductor of electricity
B) Has lustre, is malleable and ductile and a good conductor of electricity
C) Is unreactive and inert and present in traces in air
D) Shows properties of both metals and nonmetals
Explanation:
One definition of an acid is a molecule that can donate a H+ ion. So for example if you have an acid such as hydrochloric acid (HCl) in water, HCl will donate it's H+ to the H2O molecule, forming Cl- and H3O+.
In contrast, a base is a molecule that accepts H+ ions. This means a base such as NH3 reacts with H2O to form OH- and NH4.
So when pH is measured, it is the ratio of H3O+ ions to OH- ions. If there are more H3O+ ions, you then know that there are more acidic molecules in the solution, since they must be giving away their H+ ions.
So a solution with an acid in it will have more H3O+ ions (which can be described as H+ ions) in it. However, an acid by itself will have nothing to donate H+ ions to.
hope this helps also please make me the brainliest
