Answer:
Most metals have <u>luster</u> which means they <u>reflect</u> light
Explanation:
When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.
The answer is the trachea
Answer:
Process manufacturing.
Explanation:
Process manufacturing, a class of manufacturing which is associated with the formulas and the manufacturing of recipes. This type of manufacturing is different from discrete manufacturing as it deals with discrete units and assembly of the components.
<u>
This type of manufacturing is common in food, chemical, beverage, nutraceutical, pharmaceutical, cannabis, and mostly biotechnology industries. In this manufacturing, the relevant factors are the ingredients and the bulk materials rather than the individual units. </u>
<u>Thus, formation of ice is an example of process manufacturing in which different ingredients are added and using recipe of freezing.</u>
Using ideal gas equation,
Here,
P denotes pressure
V denotes volume
n denotes number of moles of gas
R denotes gas constant
T denotes temperature
The values at STP will be:
P=1 atm
T=25 C+273 K =298.15K
V=663 ml=0.663L
R=0.0821 atm L mol ⁻¹
Mass of gas given=1.25 g g
Molar mass of gas given=?
Putting all the values in the above equation,
Molar mass of the gas=46.15
