The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
Balanced chemical reaction: 2KClO₃ → 2KCl + 3O₂.
Potassium is metal from first group of Periodic table of elements, it has always oxidation number in compound +1.
Chlorine in the reactant state has oxidation number +5 (+1 + x + 3 · (-2) = 0) and it is reduced to -1 (+1 + x = 0) in the product state.
Oxygen in the reactant state has oxidation number -2 (+1 + 5 + 3 · x = 0) and it is oxidized to 0 (in molecule of oxygen) in the product state.
Answer:
2)HF bcz both fluorine and hydrogen are capable of forming only one covalent bond
Explanation:
flourine is short one electron to become stable while hydrogen has only one electron.Hydrogen cant give out its one electron fully thus it will share its one electron with flourine
Answer:
The answer will be 160 we have to just multiply it ok
The properties that describe how a material interacts with light are color and reflectivity only.
Both observations use a physical property of matter.
The physical properties of substances are the properties of substances that can be observed without changing the arrangement of atoms in the substance.
The ability of an object to scratch another is known as hardness while the ability to reflect visible light is called reflectivity. Both are physical properties.
The color of a substance results from the interaction of the molecules of the substances with light. Objects have specific colors depending on the wavelength of light absorbed and subsequently emitted by the substance.
Reflectivity deals with the ability of an object to reflect visible light.
Both color and reflectivity describe how a material interacts with light.
