All ionic compounds are polar. This is because ionic compounds consist of ions of opposite charges held together by electrostatic forces of attraction.
Charles law states that volume of gas is directly proportional to volume of gas at constant pressure
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
where
V - volume
T - temperature in kelvin
T1 - 123 °C + 273 = 396 K
T2 - 468 °C + 273 = 741 K
substituting the values
V = 38.29 L
new volume is 38.29 L

Answer:
The correct option is
C) Trial 1 will have the same calculated empirical formula as trial 2.
Explanation:
The empirical formula is the formula of a chemical compound that states the simplest whole number ratio of each of the atoms included in the compound. It is obtained by dividing the mass of an element present in the compound by the element's molar mass to find the mole ratio of the elements. The obtained mole value for each element is then divided by the smallest number of moles obtained in the division.
By definition the composition and ratio of elements combined in a chemical compound is fixed, therefore trial 1 will have the same calculated empirical formula as trial 2.
