Catalytic hydrogenation causes the oil to become saturated. So hydrogenated vegetable oil has fewer trans fatty acids and thereby less kinks. The greater the unsaturation (double bonds) the higher is the "kinks" in the fatty acid chains. Hydrogenated vegetable oil have higher melting point causing them to be solids at room temperature such as margarine. In the absence of double bonds (hydrogenated) the fatty acids pack tightly in a crystal lattice. Hydrogenated vegetable oil is likely to clog arteries.
Hey there!:
Given % of Mn=59.1% means 59.1 g of Mn present in 100 g of manganese fluoride.
Molar mass of Mn= 54.938 g/mol
Moles of Mn = mass / molar mass
59.1 /54.938 => 1.07 ≈ 1 mol.
and % of F=40.9% means 40.9 g of of F present in 100 g of manganese fluoride.
Molar mass of F=18.998 g/mol
Moles of F :
40.9 / 18.999 => 2.15 mol ≈ 2 mol.
The mole ratio between Mn:F= 1 : 2
Therefore the empirical formula of manganese fluoride:
=> MnF2=Mn1F2
Hope that helps!
Answer:
Explanation:
Any densities less than 1g/cm3 will float, while objects with densities over 1g/cm3 will sink.
You can harm ur self if you dont know variables . Bcs the values of variables should limit.
Answer: D. Use tools to help improve their senses when they make observations.
Observation is the outcome of a scientific procedure, which is followed to answer the questions related to a scientific inquiry. In order to make observation scientists need to use tools that can help in improving their senses like visual, sensation and hearing aids, so as to make observation accurate, and conclusive in a research.
