Answer:
The half-life varies depending on the isotope.
Half-lives range from fractions of a second to billions of years.
The half-life of a particular isotope is constant.

Answer: 0.082 atm L k^-1 mole^-1
Explanation:
Given that:
Volume of gas (V) = 62.0 L
Temperature of gas (T) = 100°C
Convert 100°C to Kelvin by adding 273
(100°C + 273 = 373K)
Pressure of gas (P) = 250 kPa
[Convert pressure in kilopascal to atmospheres
101.325 kPa = 1 atm
250 kPa = 250/101.325 = 2.467 atm]
Number of moles (n) = 5.00 moles
Gas constant (R) = ?
To get the gas constant, apply the formula for ideal gas equation
pV = nRT
2.467 atm x 62.0L = 5.00 moles x R x 373K
152.954 atm•L = 1865 K•mole x R
To get the value of R, divide both sides by 1865 K•mole
152.954 atm•L / 1865 K•mole = 1865 K•mole•R / 1865 K•mole
0.082 atm•L•K^-1•mole^-1 = R
Thus, the value of gas constant is 0.082 atm L k^-1 mole^-1
Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
You have to take the longest chain with the functional group as the main chain. Which means the name will end in ‘hex-1-ene’. The ‘1’ is for the place of the functional group. This has to be the smallest number possible. So no ‘hex-5-ene’. Then for the first part, we need to say something about the place and the kind of the branch. In this case, it is a propylgroup on the 4th carbon of the main chain. We will not take the 3rd carbon because we already decided to count from the right. The total name will then be: ‘4-propylhex-1-ene’.
