Must be C because the liquid fuel is Codium nitrate to be used in rocket engines
Answer:
a) 21 bonds , and 4 bonds
b) bond angles , a < 109.5° , b ≈ 120° c < 109.5° d,e < 120° f ≈ 120° g ≈ 109.5°
c) 6 carbon atom are sp² hybridized
d) two carbon atoms are sp³ hybridized,
two oxygen atoms are sp³ hybridized
Nitrogen is not sp³ hybridized , it has sp² hybridization
e) vitamin B6 exhibit delocalized bonding, because the three double bond in ring are delocalized over 5 carbon atoms and one nitrogen atom , they are formed due to 6 p orbitals of 5 carbons and 1 Nitrogen atom. The bonding in vitamin B6 is similar to the Benzene.
Explanation:
Answer:
8.801×10^-18 moles Ca
Explanation:
5.3 X 10^6atoms* (1mol/6.022*10^23) = 8.801×10^-18 moles Ca
In order to compress a gas, high pressure should be met. <span>There are three major groups of compressed gases stored in cylinders: liquefied, non-liquefied and dissolved gases. In each case, the pressure of the gas in the cylinder are high. Hope this helps.</span>
