Answer: 1000°F
Explanation:
As heat starts to attack the steel trusses, the steel will fail without flame at 1000°F
We can use the ideal gas law equation to find the number of Cl moles in the container
PV = nRT
where
P - pressure - 1.1 atm x 101 325 Pa/atm = 111 458 Pa
V - 17.8 x 10⁻³ m³
n - number of moles
R - universal gas constant 8.314 Jmol⁻¹K⁻¹
T - temperature in Kelvin - 273 + 29 °C = 302 K
substituting these values in the equation
111 458 Pa x 17.8 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 302 K
n = 0.790 mol
molar mass of Cl₂ = 71 g/mol
therefore mass of Cl₂ = 0.790 mol x 71 g/mol = 56.1 g
mass of Cl₂ present - 56.1 g
RbOH + HBr = RbBr + H₂O
NaOH + HClO₄ = NaClO₄ + H₂O
rubidium bromide RbBr and sodium perchlorate NaClO₄ are formed by the strong basis and the strong acid
pH=7
Answer:
A) 2-pentene
Explanation:
We count from side where we encounter double bond closest so that's going to be from left to the 2nd carbon. Total carbons are 5.
Thus pent- for prefix of 5 carbons and -ene as suffix for double bond.
2- for locant of double bond.
Thus, 2-pentene
