Answer:
ethyl - 3- heptanol mouthing
<u>Answer:</u> The equilibrium partial pressure of phosgene is 7.34 atm
<u>Explanation:</u>
The given chemical equation follows:
The expression of 
for above equation follows:
We are given:
Equilibrium partial pressure of CO = 
Equilibrium partial pressure of chlorine gas =
Putting values in above equation, we get:
Hence, the equilibrium partial pressure of phosgene is 7.34 atm
Iodine has 53 protons. For question 82, the number 127 stands for neutrons plus protons. So the neutron for I-127 is 74. For 83, according to the definition of isotopes, they need to have the same number of protons and different number of neutrons. I-127 and I-131 satisfy these requirements. For 85, the half life of I-131 is 8 days which means after 8 days, only half of sample remains unchanged. So if 80 gram change to 1.25 gram, it goes through 6 half life. So it took 48 days.
Answer:
molar mass of C₃H
₈ = 44 g/mole
Explanation:
Computation of the amount of oxygen that reacts
.
⇒ 75 - 12.5
⇒ 62.5 cm³
Computation of proportion of hydrocarbons
2 mole hydrocarbons 3n+1 oxygen
⇒ 3 n + 1 = [62.5 × 2] / 12.5
⇒ 3 n + 1 = 10
⇒ n = 3
So,
Formula of the hydrocarbon is C₃H
₈
Computation of molar mass of C₃H
₈
⇒ [12×3] + [1×8]
⇒ 44 g/mole
Metals are hard and no metals are liquid
