Answer: Zinc nitride (Zn3N2) is an inorganic compound of zinc and nitrogen, usually obtained as (blue)grey crystals. It is a semiconductor. In pure form, it has the anti-bixbyite structure.
Chemical formula: Zn3N2
Space group: Ia-3, No. 206
EC Number: 215-207-3
Appearance: blue-gray cubic crystals
Explanation:
A. Phase changing. When phase changes nothing chemically changes about the substance, its still the same thing.
Answer:
A- Energy from sunlight becomes glucose during photosynthesis
Explanation:
The law of conservational photosynthetic energy states that atoms cannot be created nor destroyed; the atoms can only be rearranged into new molecules and ions. This implies that the enzymes in photosynthesis are aided by energy to transform into glucose, which the plant needs.
Answer:
The answer to your question is: letter E
Explanation:
A. This option is correct, the n = 3 shell only has subshells: s, p and d, and shell n = 4 or 5 have f subshell.
B. This option is true in subshell p could be at most 6 electrons and 3 suborbitals.
C. This option is correct orbital "s" is a sphere.
D. This option is correct, in subshell d could be at most 10 electrons and 5 orbitals.
E. This option is false, hydrogen only has 1 electron and then one subshell (s).
