Answer:
The options are not given, here are the options.
metal
a. Metal
b. a metalloid
c. a non-metal
d. a gas
The correct option is C.
Non metal
Explanation:
Henry should classify it as non metals because non metals are substances or elements that are poor conductors of heat and electricity they break easily I .e meaning they lack the ducibility of metals, meaning they cannot be stretched, they are brittle, they are not shiny and does not reflect light, they have high electronegativities that is they have atoms that can hold electrons to what they have.
Hyperglycemia is when blood sugar levels are always higher, only happens when insulin doesn’t respond properly. Without insulin glucose can’t get into cells and so it builds up in the bloodstream.
The equation that scientists could use to find the wavelength of the emission lines of the hydrogen atom would be that of Balmer.
The wavelength of the emission lines of the hydrogen atom can be derived using the Balmer series:
1/λ 
Where λ = wavelength, 
= Rydberg constant, and n = level of the original orbital.
The equation becomes applicable in getting the wavelength of emitted light when electrons in hydrogen atoms transition from higher (n) orbital to lower orbital (2) levels.

You may find bellow the balanced chemical reactions.
Explanation:
To balance chemicals equation the number of atoms of each element
entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.
2. Single displacement: Zn + 2 HCl → ZnCl₂ + H₂
3. Decomposition: NiCl₂ → Ni + Cl₂
4. Double displacement: 2 LiI + Pb(NO₃)₂ → PbI₂ + 2 LiNO₃
5. Double displacement: BaCl₂ + H₂SO₄ → BaSO₄ + 2 HCl
6. Single displacement: Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag
7. Synthesis (combination): 2 Na + O₂ → 2 Na₂O
8. Solid mercury (II) oxide decomposes to form liquid mercury and oxygen.
2 HgO (s) → 2 Hg (l) + O₂ (g) (decomposition reaction)
9. A solution of zinc hydroxide reaction with phosphoric acid (H₃PO₄) to produce solid zinc phosphate and water.
3 Zn(OH)₂ + 2 H₃PO₄ → Zn₃(PO₄)₂ (s) + 6 H₂O (l) (double displacement reaction)
where:
(s) - solid
(l) - liquid
