Butane is from the family of alkanes with –ane as its family name. The but- prefix stands for having four carbon atoms. The C4H10 is the general formula of butane and can also represent other forms or structures of butane. However if the question asks for the molecular formula of butane, think of how many electrons it can share to the hydrogen atom. The carbon atom can share 4 and hydrogen 1. So if the three hydrogen atoms are attached to the first carbon, the other shared electron is attached to the second carbon. The second carbon atom can accommodate two hydrogen and 1 carbon. The third carbon can accommodate 2 hydrogen atoms and 1 carbon and the fourth carbon can accommodate 3 hydrogen atoms. The molecular formula is CH3-CH2-CH2-CH3.
Answer:
Light Emitting Diode (LED) lighting device.
Explanation:
Light Emitting Diode (LED) is an electrical component that produces light when a current flows through its terminals. It has a long life span and conserves energy coupled with brilliant lightning effects. Also, it is light in weight and generate no heat compared to other lighting devices. It is majorly recomended because of its diverse properties and efficient functions.
This componet can be incorporated to produce an energy efficient and long lasting lighting device. So, Ron should use a Light Emitting Diode (LED) lighting device.

87.75 grams of sodium chloride (NaCl) are required to prepare 500. mL of 3.00 M solution.
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.
A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.
Given,
Volume of NaCl = 500ml
Concentration = 3M
Moles = Concentration × volume
= 3 × 0.5
= 1.5 moles
Mass = moles × molar mass
= 1.5 × 58.5
= 87.75 g
Therefore, 87.75 grams of sodium chloride (NaCl) are required to prepare 500. mL of 3.00 M solution.

property of marker ink
Explanation:
Intensive property: It is the property of substance which is independent of quantity of substance. Color of an ink is an intensive property.
Extensive property: It is the property of substance which depends upon quantity of substance which is just opposite to intensive property. Volume of an ink is an extensive property.
