The correct answer is molecular formula = 2 x empirical formula
The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.
All of them are the answer
It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
Synthesis cause A + B --> AB Equation: 2Na + Cl2 --> 2NaCl
Answer:
178 torr
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 5 mL
V₂ = 5 mL (Closed container)
P₁ = 95.0 torr
P₂ = ?
T₁ = 28.0 ºC
T₂ = 290 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28 + 273.15) K = 301.15 K
T₂ = (290 + 273.15) K = 563.15 K
Using above equation as:
Solving for V₂ , we get:
P₂ = 178 torr
