Answer:
36.8 L
Explanation:
We'll begin by converting 80 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
T(°C) = 80 °C
T(K) = 80 + 273
T(K) = 353 K
Finally, we shall determine the volume occupied by the helium gas. This can be obtained as follow:
Number of mole (n) = 1.27 moles
Temperature (T) = 353 K
Pressure (P) = 1 atm
Gas constant (R) = 0.0821 atm.L/Kmol
Volume (V) =?
PV = nRT
1 × V = 1.27 × 0.0821 × 353
V = 36.8 L
Thus, the volume occupied by the helium gas is 36.8 L
A metallic bond is a force that holds atoms together in a metallic substance.
Potassium hexacyanochromate(III)
A systematic name is a name given in a systematic way to a
chemical substance, out of a definite collection.
The systematic name for the coordination compound k3 cr(cn)6
is Potassium hexacyanochromate(III). This compound contains potassium (k3), six
cn which is called hexacyano, and cr (chromium).
Answer:
Explanation:
Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth
