The product when an unsaturated hydrocarbon undergoes complete addition would be a saturated molecule. These saturated hydrocarbons becomes Alkanes where these molecules are only single-bonded in contrary to unsaturated hydrocarbons which have multiple bonds between atoms.
The formation of hydrogen cyanide, HCN is formed by reacting hydrogen gas, carbon and nitrogen gas, expressed in the following expression below:
<span>½ H2 (g) + C (s) + ½ N2 (g) → HCN (g) ΔHof = 135 kJ
</span>
At standard conditions, hydrogen and nitrogen exist as gases while carbon is solid. This is also an endothermic reaction due to the positive <span>ΔHof</span>
Answer:
definition -
Explanation:
the breakdown of a compound into oppositely charged ions
The answer to this item is determined by using the proper conversion factors and the dimensional analysis. For the given units, meter and centimeters, the conversion from millimeters are as shown below,
1 m = 1000 mm
1 cm = 10 mm
Conversion of 5.3 mm³ to m³.
= (5.3 mm³)(1 m/1000 mm)³ = 5.3 x 10⁻⁹ m³
Conversion of 5.3 mm³ to cm³.
= (5.3 mm³)(1 cm/10 mm)³ = 5.3 x 10⁻³ cm³
The answer to this item is therefore letter B. 5.3 x 10⁻⁹ m³.
Answer:
D. 6.25 J
Explanation:
∴ k = 50 N/m
∴ Δx = 0.5 m
⇒ EPE = 1/2*50 N/m*(0.5m)²
⇒ EPE = 6.25 N.m = 6.25 J
