Answer:
Oxygen
Explanation:
Any Hydrocarbon + Oxygen ----> Carbon Dioxide + H2O (Water vapour, gas, water)
Genetics file means genes so it’s genetic file
The physical property that is similar to glass, water, dry ice , plastic wrap and air is ; Color ( colorless substances )
All the listed elements share one physical property which is in their color. glass, water, dry ice, plastic wrap and air are all colorless in nature.
Physical properties of elements/substances are measurable or observable properties of an element that does not affect the chemical composition of the element/substance. physical properties describes the physical appearance of a substance.
Hence we can conclude that the physical property that is similar to glass, water, dry ice, plastic wrap and air is ; Color

Answer:
Zn (s) + HCl (aq) → ZnCl₂ (aq) + H₂ (g) ↑
Explanation:
Let's define the reactants:
Zn (s)
HCl (aq)
One of the product is: H₂ (g)
This reaction can also produce ZnCl₂ (s)
Let's make the reaction:
Zn (s) + HCl (aq) → ZnCl₂ (aq) + H₂ (g) ↑
Notice that the the hydrogen gas is released from the tube, that's why the up arrow.
This is a redox reaction because the Zn and H chage their oxidation states.
Zn ⇄ Zn²⁺ + 2e⁻ Oxidation (it released two electrons)
Oxidation state is increased
2H⁺ + 2e⁻ → H₂ Reduction (It gained two electrons)
Oxidation state is decreased
The oxidation state of elements at ground state is 0
