Answer:
The correct answer is A. 3O₂ + 2Al → 2AlO₃
Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.
For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.
Mass of oxygen = 16 x 3 = 48 AMU
Mass of aluminium = 2 x 27 = 54 AMU
Total molecular mass of the reactants = 102 AMU
Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.
Hence, the total mass of the matter remains the same.
Answer:
Polyphyletic relationships .
Explanation:
The primary goal of modern systematics is construct 'family trees' that exhibit polyphyletic relationships because systemics deals with grouping or organising living organisms into groups base on biological meanings of function and polyphyletic relationships which is organising or grouping of organisms that don't have common ancestors Into different groups or unrelated organisms.
The answer would be: <span>neuregulin 1
</span>Schizophrenia is a psychiatric disease that involves symptoms related to brain inability to understand reality. Neuregulin 1 or NRG1 found to be linked with schizophrenia. Neuregulin 1 has a role in the neurobiological function and some of it related to the pathophysiology of the schizophrenia.
