Answer:
boiling point is the physial property of matter
Answer:(D) different number of neutrons per atom
Explanation: Honestly, I just looked it up on Socratic.
The answer is 18.
This is obtained by multiplying the three oxygen atoms in NO₃, that are inside the parenthesis by the number two outside the parenthesis. The number 2 is there because it comes from associating with Fe ²⁺ .
3×2=6 oxygen atoms present in the formula.
Then multiplied by the 3 that's in front of the formula (that indicates how many molecules).
6 x 3= 18
Answer:
Molecular formula = C₁₀H₂₀
Explanation:
Given data:
Empirical formula = CH₂
Molar mass = 140.27 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Now we will calculate the empirical formula mass.
CH₂ = 12 × 1 + 1× 2
CH₂ = 12 +2
CH₂ = 14
n = 140.27 / 14
n = 1
0
Molecular formula = n (empirical formula)
Molecular formula = 10 (CH₂)
Molecular formula = C₁₀H₂₀
