What is the extended and shortened structural formula for 2-methylpentane

Chemistry

kotykmax [81]3 years ago
6 0

The structural formula for 2-methylpentane is in Figure 1. It shows all the C-C and C-H bonds explicitly.

The bond-line formula for 2-methylpentane is in Figure 2. We assume that a carbon atom is at the ends and junctions of the lines. We do not show the H atom, but we mentally assume that there are enough to give each carbon a valence of four.

A condensed structural formula is designed to be typed <em>all on one line</em>. We could write the condensed structural formula for 2-methylpentane as either (CH₃)₂CH-CH₂-CH₂-CH₃ or CH₃CH(CH₃)CH₂CH₂CH₃.

The horizontal C-C bonds are <em>optional </em>— you can include or omit them as desired.

How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 30.6 moles of water vapor?
belka [17]
H₂ + CO₂ ⇄ CO + H₂O

1 mol H₂ - 1 mol H₂O
x mol H₂ - 30.6 mol H₂O

x=30.6*1/1=30.6 mol  (<span>theoretically)</span>

How many grams are in 0.220 mol of Ne?
yawa3891 [41]

Answer:

Mass = 4.44 g

Explanation:

Given data:

Number of moles of Ne = 0.220 mol

Mass in gram = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of Ne = 20.2 g/mol

by putting values,

0.220 mol = mass/ 20.2 g/mol

Mass = 0.220 mol × 20.2 g/mol

Mass = 4.44 g

The solid has a mass of 180 g. What is the den of the solid?
Alja [10]
Density requires at least two things. In this case we would need volume of the object in addition to the mass. Density is equal to the mass divided by volume p = V/m

What is the symbol of the neurtal element that has four 4p electrons?
ddd [48]
If a neutral element has 4 electrons in its
4P shell then its electron configuration is 1S2 2S2 2P6 3S2 3P6 3D10 4P4. therefore the sum of electrons = 2+2+6+2+6+10+4=32 electrons
since the element is neutral, so number of electrons = number of protons. hence number of protons that element has is 32
the only element that has 32 protons is germanium
so the answer is Ge
