The formula for C2H6 is CH3-CH3.

Explanation:

The given formula C2H6 is the molecular formula depicting the integral number of atoms of combining elements. From this formula, it can confirmed that 2 atoms of carbon has combined with 6 atoms of hydrogen, but the arrangement of these atoms and the bonding between them is unclear from the given formula.

In order to determine the bonding occurring between elements and how the atoms are arranged or bonded with each other, we use structural formula representation. It is known that a single carbon atom that should have four bonds to attain the stable state and each hydrogen atom can share only one electron.

So the structural formula of C2H6 can be written as CH3-CH3. This indicates that three hydrogen atoms will be bonded with a single carbon atom leading to formation of single bond between two carbon atoms surrounded by three hydrogen atoms on either sides of carbon atoms. This material is termed as ethane and it falls in alkalies group of organic compounds.

Answer:

The general Formula given for alkanes is $CnH2n+2$ and hence it shows $C_2 H_6$ is the second alkane and is named ethane.

Explanation:

Formula here shows two molecules of $CH_3$ are joined that is the formula for Ethane becomes $CH_3-CH_3$ .

If we break the name ethane it gives two divisions eth and ane the former means to while the latter represents the alkane family. Hence the formula represents two carbons in alkane family which makes it $C_2H_6$ .

The element antimony has an atomic weight of 122 and consists of two stable isotopes antimony-121 and antimony-123. the isotope

grin007 [14]

Answer:- 123 amu.

Solution:- The formula to calculate the average atomic mass of an atom is:

Average atomic mass = mass of first isotope(abundance of first isotope) + mass of second isotope(abundance of second isotope)

Note: The percent abundance is converted to decimals.

mass of Sb-121 is 121 amu and it's percent abundance is 57.3% and in decimal it is 0.573. Percent abundance of Sb-123 is 42.8% and in decimal it is 0.428. We are asked to calculate it's mass. The average atomic mass of Sb is given as 122.

Let's say the mass of Sb-123 is M and plug in the values in the formula and do calculations:

122 = 121(0.573) + M(0.428)

122 = 69.333 + M(0.428)

On rearrangement:-

M(0.428) = 122 - 69.333

M(0.428) = 52.667

$M=\frac{52.667}{0.428}$

M = 123

So, the mass of Sb-123 is 123 amu.

Answer: The pressure of the He is 2.97 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

$p_{total}=p_{N_2}+p_{O_2}+p_{He}.$

Given : $p_{total}$ =total pressure of gases = 6.50 atm

$p_{N_2}$ = partial pressure of Nitrogen = 1.23 atm

$p_{O_2}$ = partial pressure of oxygen = 2.3 atm

$p_{He}$ = partial pressure of Helium = ?

putting in the values we get:

$6.50atm=1.23atm+2.3atm+p_{He}$

$p_{He}=2.97atm$

The pressure of the He is 2.97 atm

alexgriva [62]

I think the answer would be dependent variable. An unknown or changeable quantity is called a dependent variable. It is what you measure in the experiment and what is affected during the experiment. Hope this answers the question. Have a nice day.
