We can use the ideal gas law equation to find the volume of the balloon.
PV = nRT
where
P - pressure - 0.992 atm x 101 325 Pa/atm = 100 514 Pa
V - volume
n - number of moles - 8.80 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in kelvin - 25 °C + 273 = 298 K
Substituting these values in the equation
100 514 Pa x V = 8.80 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
V = 217 L
volume of balloon is 217 L
Answer:
sulfuric acid
Explanation:
a strong acid that soluble in water.
To balance a chemical equation, you want the same amount of elements to equal the same on both sides.
Step1. Write equation out
[CH4 + Cl2 ---> CCl4 + HCl]
C:1; H:4; Cl:2 C:1; H:1; CL:5 /// Cl = 5 since 4Cl + 1Cl
The Carbon element is balanced, but Hydrogen isn't.
So to balance it we will add a coefficient behind HCl, so now
[CH4 + Cl2 ------> CCl4 + 4HCL]
C:1; H:4; Cl:2 C:1; H:4; CL:8 ///// Carbon and hydrogen are balanced, but now Chlorine is not. Now we balance that element by addind a coefficiant behind CL2////
[CH4 + 4Cl2 -----> CCl4 + 4HCl]
C:1; H:4; Cl:8 C:1; H:4; CL:8 ///// So now that we added a 4*Cl2, it equals to Cl:8. So now what most people want to see is if every element is at its lowest balance, so we see if we can any coefficient lower. Just like simplifying if possible.
Ok what’s the question sir
Answer:
The strength of an individual H bond depends on the polarity of the H-X bond and therefore on the electronegativity of X ( the more delta positive the H atom, the stronger the electrostatic force of attraction between it and a lone pair of electrons). Thus, on a per bond basis, HF H bonding is strongest. However, as water has two H atoms, each molecule can form two H bonds so on a per molecule basis, water H bonding is strongest (this is evidenced by the boiling points of the three substances; NH3 < HF < H2O.)
