    ch4,no,Br2 is that correct




    Three of the gases in the list could behave as greenhouse gases.

    • CH4 (g)

    • F2 (g)

    • NH3 (g)

    • Ne (g)

    • NO (g)

    • Br2 (g)

    Yes, yes, no..

    The 3 organic or organicish gasses are greenhouse gasses. Bromine isn't a greenhouse gas.


    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    i think 1 and 2 is that correct please help
    From the five scenarios described below, identify (by ticking the adjacent box) the two scenarios that could possibly lead to no overall change in GMST in this way.

    • The atmospheric CO2 concentration decreases while the albedo of the surface (which isn't covered by ice and snow) increases.

    • The atmospheric H2O concentration increases while the solar constant decreases.

    • The albedo of the surface (which isn't covered by ice and snow) increases while the fraction of Earth's surface covered with ice and snow decreases.

    • The fraction of Earth's surface covered with ice and snow decreases while the atmospheric H2O concentration increases.

    • The volcanic aerosol content in the atmosphere decreases while the fraction of Earth's surface covered with ice and snow decreases

    Why does this feel like I'm being asked to do someone else's homework....without compensation?
