Answer:
A)less
Explanation:
This is because obviously if it's less metallic then it won't have similar traits to metals as well, there's less metal.
Answer:
a. ΔH⁸ = -1420 kJ/mol b. ΔH⁸ = -1144.84 kJ/mol
Explanation:
a.
C₂H₄ (g) + 3 O₂ (g) ------------------------ 4 CO₂ (g) + 2 H₂O (l) ΔH⁸ = ?
ΔH⁸f kJmol 52.47 0 -399.5 -285.83
ΔH⁸ = 2(-399.5) + 2 (-285.83) - (52.47)
ΔH⁸ = -1420 kJ/mol
b.
H₂S (g) + 3 O₂ (g) ---------------------- 2 H₂O (l) + 2 SO₂ (g)
ΔH⁸f kJmol -20.50 0 -285.83 -296.84
ΔH⁸ = 2(-285.83) + 2 (-296.84) - (-20.50)
ΔH⁸ = -1144.84 kJ/mol
Explanation:
Steroid contains a steroidal ring and are devoid of fatty acid chain. The steroidal nucleus is a fused ring consisting of three six membered rings, and a five membered ring.
Examples of steroidal molecules include, cholesterol, steroidal hormones such as estrogen(estradiol) progestrone, testoterone and corticosteroidal hormones such as cortisol, aldosterone and cortisone.
