If i have 4 moles of a gas ata pressure of 5.2 atm and a volume of 15 liters, what is the temperature?

273.51 K

Explanation:

The Ideal gas law given by the combination of Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law is given as follows:-

PV=nRT

Where,

P =   the pressure of the gas

V  =  the volume it occupies

n  = the number of moles of gas present in the sample

R =  the universal gas constant, equal to  0.0821  atm L /mol K

T  = the absolute temperature of the gas

∴ T = PV/nR = 5.2 *15/0.0821 * 4 = 273.5 K

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

hcl + naoh → h2o + nacl

explanation:

hcl + naoh → h2o + nacl   is the reaction that is correctly balanced.

however, pcl3 + h2 → ph3 +3hcl, 2ca+ 3cl2 → cacl3, and c5h12 + 5o2 → 5co2 + 6h2o are not correctly balanced.
