М(СО₂)=165 г
н(СО₂)=м(углекислого газа)/М(СО₂)
Н=Nₐ*м(углекислого газа)/М(СО₂)
Н=6.022*1023 * 165/44.01=2.258*10²⁴
Answer:
D. The flesh should return to normal after you press it.
Explanation:
The water content stored in the flesh of the fish, paired with the elasticity are both indicators of freshness, and will cause the flesh to return to normal after its been pressed.
Answer:
477 nm
Explanation:
Using the expression for the energy as:
Where,
h is Plank's constant having value
c is the speed of light having value
is the wavelength of the light
Given,
Also, 
So, Energy for one atom = 
Thus, applying values as:


( 1 m =
nm )
They speed up and spread out when heated
they slow down and compress when cooled
