Answer:
a. True
Explanation:
The gases that we study are governed by different laws of physics. Gases behaves according to some given set of laws like the Universal gas laws, Boyles law, Charles law, Gay Lussac's law and many more.
But we do not see a definite pattern or rule when we study solids or liquids. The behavior of the solids and liquids are not described by the set of laws which are applied regardless of the identity of the substance.
Answer:
H2
Explanation:
In the first place it is necessary to consider that these two elements will be their diatomic form initially, that is, H2 and N2.
first we should check the equilibrium constant Kp tables in this case at a temperature of 3000K
Value for dissociation reaction of H2 in Kp = -3.685
Value for dissociation reaction of N2 in Kp = -22.359
Equilibrium constant for H2 dissociation is higher than N2 dissociation. so for this comparation H2 is more likely to dissociate.
Answer: 3.41 mL
Explanation: Solution:
Use Combine gas law to solve this problem.
P1V1 / T1 = P2V2 / T2
First convert temperature to K
T1 = 47 °C + 273 = 320 K
T2= 107°C + 273 = 380 K
Derive to find V2:
V2 = P1 V1 T2 / T1 P2
Substitute the values:
V2= 1.03 atm x 2.20 mL x 380 K /
320 K x 0.789 atm
= 3.41 mL
Cancel out the units of atm and K so the remaining unit is in mL.
