Natural diamonds are made very deep within earth's surface where high temperatures and pressure exist naturally, thus making them much more difficult to obtain, and making them a more expensive option that Swarovski Crystal.
Answer:
Explanation:
Reducing agent
Reducing agent is an element or compound that loses or donates an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons,it is said to have been oxidized.
2Al(s) + 3Cl₂ → 2AlCl₃
Forming the equation:
2(28) + 3(223) = ΔH + 2(111)
ΔH = 503 kJ
Writing this outside of the reaction equation:
ΔH = -503 kJ
4 C₃H₅(NO₃)₃(l) = 12 CO₂(g) + 6 N₂<span>(g) + 10 H</span>₂O(g) + O₂<span>(g)
4 x ( 227.0995 ) g ---------------> 10 x ( 18.0158) g
mass of </span><span>nitroglycerin-------------> 120 g
</span>m ( nitroglycerin ) = 120 x 4 x 227.0995 / 10 x <span>18.0158
</span>
m ( <span>nitroglycerin ) = 109007.76 / 180.158
m ( </span>nitroglycerin ) = 605.06 g
hope this helps!
