Answer:
I doo not know this
Explanation:
dont mine me just need points
Several centimeters of lead. Gamma rays have the highest penetrating power and therefore need a thick layer of something, in most cases lead, to prevent penetration. (This is why if you have ever go to the dentist they put a heavy thing on you made of lead, to prevent the penetration of gamma rays that can destroy your most important organs).
Balanced chemical equation:
2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)
Explanation:
The correct chemical reaction is:
C₃H₆N₆ (l) + O₂ (g) → CO₂ (g) + H₂O (g) + N₂ (g)
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
Balanced chemical reaction:
C₃H₆N₆ (l) + (9/2) O₂ (g) → 3 CO₂ (g) + 3 H₂O (g) + 3 N₂ (g)
To have integer numbers we multiply the equation with 2 to obtain:
2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

Answer:
D. All of the above are true
Answer:
The correct answer is D) 44 atm
Explanation:
We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. You can add the amount of moles and then calculate the pressure, using the ideal gas formula. We convert the temperature in Celsiud into Kelvin : 0°C= 273K---->
27°C=27 + 273= 300K
PV= (nH+ n0+ nHe)x RT
P=((nH+ n0+ nHe)x RT)/V=
P=((3 mol + 6 mol +9 mol)x 0,082 l atm/ Kmol x300K)/10 L
<em>P=44, 28 atm</em>
