Answer:
because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain
"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."
What is isomer?
Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.

How many moles are there in 17.6g NaOH?
Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.
Mathematically,
number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH
Molar mass of 1 mole of NaOH= 40 g/mol
mass of NaOH= 17.6g
Substituting all the given values in the above equation, we get
number of moles of NaOH = 17.6g ÷ 40 g/mol
number of moles of NaOH =0.44moles
Therefore, 0.44moles are there in 17.6g NaOH.

2.0 L
11.2 L
22.4 L
44.8 L
Answer:
44.8
Explanation:
According to standard temperature and pressure and ideal gas equation , the volume of 2 mole of chlorine gas at STP is 44.8 liters.
What are standard temperature and pressure conditions?Standard temperature and pressure are defined as a standard set of conditions required for experimental measurements which are established to allow comparison between different sets of data.
Standards which are commonly used are those International Union of pure and applied chemistry and national institute of standards and technology.These are not universally accepted standards but are the ones which are commonly used.
Standard conditions of pressure and temperature are necessary to define standard reference conditions used to express volumes of liquids and gases.
These values are important to physicists, chemists ,engineers ,pilots and navigators.On substituting values in ideal gas equation, volume= 2×8.314×273/1=44.8 liters.
Thus, the volume of 2 mole of chlorine gas at STP is 44.8 liters.

What happens during the rock cycle?
During spontaneous fission, a nucleus of 25498Cf can produce 11846Pd, four neutrons, and what other nuclide?
Answer: 52Te - Tellurium
Explanation: Radioactivity occurs when an unstable nucleus of an element decompose into a stable element by emitting particles or forms of eletromagnetic energy. There are types of radioactivity and Spontaneous Fission is one of them.
In Spontaneous Fission, the unstable, also called parent, nucleus splits into two smaller nuclei and emitts one or more neutrons.
The reaction spontaneous fission of Cf is represented below.
25498Cf ⇒ 11846Pd + 4n + X
The characteristics of each element of the equation are:
1) The element Cf has atomic mass 254 and atomic number 98.
2) Element Pd has atomic mass 118 and atomic number 46.
3) Neutron is represented as n, has no atomic number and atomic mass 1.
Given these properties, to determine the other nuclide, we have to find out the nuclide's atomic number, as each element in the periodic table has its own atomic number.
At the left side of the equation, atomic number is 98. At the right side, element X's atomic number is
98 - 46 + 0 = 52
In the periodic table, the element with atomic number 52 is Tellurium, whose symbol is Te.
The other nuclide for the spontaneous fission is Tellurium (Te).

How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.
