4Al + 3O2 —> 2AL2O3
Answer is D
<h2>Let us explain about green house gases</h2>
Explanation:
Green house effect
It can be explained as :
- The sun emit radiations that consist of infra red rays , ultra violet rays and visible light .
- The infra red rays (responsible for heating ) when come from sun , it travels through atmosphere and reaches earth surface .
- On striking the earth surface , it gets reflected and reflected infra red ray has greater wavelength .
- Then this reflected rays moves back through atmosphere .
- On doing so , they encounter certain gas molecules like carbon dioxide , methane etc .
- This gases absorb these rays and do not let them to escape through them .
- As a result, they get trapped .
- As we have already mention that they cause heating effect , due to this property they raise the temperature of atmosphere leading global warming .
Answer:
well it might be 1.)Cadmium Fluoride CdF2 150.4078
2.)Cadmium(II) Perfluorate Cd(FO4) 2278.403
3.)Cadmium Ferrocyanide Cd2Fe(CN) 6436.7714
Explanation:
Answer:
The temperature would be reduced by half
Explanation:
Charles' Law => V ∝ T => V = kT => k = V/T
For two sets of T vs V conditions, the system constant (k) remains unchanged and k₁ = k₂ => V₁/T₁ = V₂/T₂.
Therefore, if V₁ is reduced to 1/2V₁ = V₂ => V₁/T₁ = 1/2V₁/T₂ => V₁/T₁ = V₁/2T₂
and solving for T₂ => 1/T₁ = 1/2T₂ => 2T₂ = T₁ => T₂ = 1/2T₁
∴ The initial temperature (T₁) would be reduced by half or, T₂ = 1/2T₁
Density/Earth’s gravitational pull.
