Answer:
I'm converting this if I could remember how
2.882568
2 110321/ 125000
T-T sorry if I'm wrong I have bad memory
so I recommend not using my answer at all,
if that is even how y'all write it.
The temperature of a the gas is calculated using combined gas law formula that is P1V1/T1 = P2V2/T2
P1 = 453mmhg
V1= 700ml
T1 = 25 + 273 = 298k
P2 = 278 mmhg
V2 = 1200ml
T2= ?
T2 is therefore = T1 P2V2/p1V1
= 298 x278 x1200/ 453 x 700 = 313.5 K

A. H2 and O2
B. NO and NO2
C. P2O5 and PH3
D. CaCl2 and CaBr2
B. NO and NO2
best shows the law of multiple proportions.
law of simple multiple proportions. Law of multiple proportions, states that when two elements react with oneaother to form more than one compound, the weights of one element that combine with the fixed weight of the other element are in small whole number ratios.
Here Nitrogen, N which is fixed combines with Oxygen in two compounds in ratios 1 to 1 and 1 to 2
