The 4 major characteristics of a mineral are: -It is formed by natural processes- not man made -It is inorganic- it's not alive, it never will be -It is a crystalline solid- a definite volume and shape with a repeating structure -It can be an element or compound with a definite chemical composition- made the same each time w/ and orderly arrangement of atoms Also, another answer might <span>be: -Texture -Hardness -Luster or shine -Color/streak Hope that helps</span>
Answer:
Explanation:
element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...) molecule - two or more atoms that are chemically joined together (H2, O2, H2O, C6H12O6, etc...) compound - a substance that contains more than one element (H2O, C6H12O6, etc...)
Greetings I am DemonicPresence, the answer would be A.
Answer:
The right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"
Explanation:
Catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy Eₐ (i.e. by changing the reaction pathway), which Catalyst is not consumed in the catalyzed reaction and can continue to act repeatedly.
From the attached figure one can see that the path way A-C-D has different pathway and lower activation energy (Eₐ) than the pathway A-B-D, this means that the pathway A-C-D is a catalyzed pathway and it is faster than A-B-D.
So, the right statement is " the Pathway A-C-D involves a catalyst and is faster than A-B-D"
