Answer:
there are 2970000cm in 29.7km
Explanation:
Balanced chemical equation for the hydrogenation of glyceryl trilinolenate:
C₅₇H₉₂O₆ + 9H₂ → C₅₇H₁₁₀O₆.
Linolenic acid (octadecatrienoic acids ) is a type of fatty acid. It has 18 carbon atoms chain and three double bonds. So trilinolenate has nine double bonds.
Trilinolenate is the form of triglyceride esters of linolenic acid.
Hydrogenation is addition of hydrogen atoms at both sides of a double bond.
Answer:
MgO has a highest melting point
C5Br has lowesst
Explanation:
It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.
Answer:
The water of crystallization for the formula of the unknown hydrate is 2.
Explanation:
Mass of an unknown hydrate = 1.000 g
Molar mass of hydrate = 195.5 g/mol
MOles of unknown hydrate =
Mass of hydrate after heating = 0.781 g
Mass of water lost due to heating = x
Moles of water lost =
1 Mole of hydrate has x moles of water and 0.00512 moles of hydrate has 0.0122 moles of water then we can write:
The water of crystallization for the formula of the unknown hydrate is 2.
At first, atoms were considered to be very simple and indivisible. People form ancient times knew only of water, earth, fire, and air, not what constitutes them or how they work specifically. Now, there are 118 elements and all atoms are proven to consist of neutrons, protons, and electrons, and that's just the beginning of it.
