Answer:
d) gases that absorb infrared radiation
water vapor, carbon dioxide, methane, and other trace gasses in the Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from the Earth's surface.
A theory fits all three of these descriptions. you can test, predict, and prove or disprove a theory. hope this helps!
Answer:
Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.
Explanation:
1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).
So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.). :-)
Answer:
pH will always be less than 7
Explanation:
This is because NH3 is a relatively weak base and the resulting Acidic salt on titration might hydrolyse to form a buffer solution
