Molar mass methane ( CH₄) = 16.04 g/mol
number of moles:
mass CH₄ / molar mass
8.67 / 16.04 => 0.5405 moles
1 mole ------------------ 22.4 L ( at STP )
0.5405 moles --------- ??
0.5405 x 22.4 / 1 => 12.1072 L
hope this helps!
Answer:
Pitch:it refers to the highest and lowness of a sound.
Wavelength: It is the distance measured from one crest to another, or from one trough to another.
Refraction of Light: The light bends as it travels from one medium to another.
Reflection of Light: It happens when light bounces back after hitting a well-polished surface.
Crest: The highest point of the wave from the center.

Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Hi! Thank you for posting your question here at Brainly. I hope I would be able to help you with my answer.
When an alkyne such as 2,3-dichloropentane is treated with excess sodium amide, a two-step elimination reaction will happen. The reaction would then yield the final product in the form of 2-pentyne. Its structure is shown in the attached image.
