Answer:C. Hydrogen Bonds with themselves and entropy decreases.
Explanation:Limonene is a chiral aliphatic Hydrocarbon liquid that is relatively stable as MONOTERPENE which cracks at high temperature to produce ISOPRENE. D-limonene is produced from CITRUS FRUIT through CENTRIFUGAL SEPARATION AND STEAM DISTILLATION. The most widely used conversion of limonene is to CARVONE.
The water molecules around LIMONENE forms Hydrogen Bonds with themselves and entropy of the reaction decreases,the name Limonene was obtained from the PEEL OF LEMON.
Answer:

Explanation:
A descriptive method is commonly known as a research method for describing the properties or features of the research area being investigated. Descriptive research is usually conducted by studying the trends of the phenomenon without changing the value of any variable in the system. Thus, the correct answer is option a.
Answer:
10kg = 10 x 1000 = 10,000g
Explanation:
To know the quantity with the largest mass, we have to express all the units in grams:
for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g
0.001kg = 0.001 x 1000 = 1g
1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g
2 x 10²cg = 2 x 10² x 10⁻² = 2g
10kg = 10 x 1000 = 10,000g
Note:
10⁻ ¹ deci(d)
10⁻² centi(c)
10⁻³ milli(m)
10⁻⁹ nano(n)
10³ kilo(k)
Answer:
Ammonium chloride, iron ,Sulphur and salt mixed together... they can be separated in the following methods.
1. Ammonium chloride is separated by sublimination... NC4CI is sublimable. Heat the mixture in a china dish and collect the funds of NC4CI (sublimable substance)
2. Bring a magnet close to the remaining mixture. Iron is magnetic substance and thus, it will be attracted towards the magnet. Iron is separated.
3. Sulphur is insoluble in water and salt is soluble. Add water to the remaining mixture and then wait for sedimentation. Separate the sulphur by decantation.
4. Heat the filtered salt solution to obtain salt.
Answer:
C: increases
Explanation:
Temperature is directly proportional to volume. If the temperature of a substance increases, the volume also increases. If the temperature decreases the volume also decreases.
According to Charles's law "the volume of fixed mass of gas varies directly as its absolute temperature if the pressure remains constant". Although this is an ideal gas law, it is also applicable to most substances.
As the temperature is raised, the volume also behaves proportionally that way.
