Answer:

D) C₄H₉OH

Explanation:

In chemistry, isomers are chemical substances with the same formula (That is, same atoms but in different structures).

For the compound C₂H₅OC₂H₅ there are 4 atoms of C, 10 atoms of H and 1 atom of O.

A) CH₃COOH . This compound have 2 atoms of C, 4 atoms of H and 2 atoms of O. Thus, isn't an isomer.

B) C₂H₅COOCH₃. There are 4 atoms of C but 8 atoms of H and 2 atoms of O. Isn't an isomer

C) C₃H₇COCH₃. There are 5 atoms of C, 10 atoms of H and 1 atom of O. Thus, isn't an isomer

D) C₄H₉OH. Here, you have 4 atoms of C, 10 atoms of H and 1 atom of O. That means this structure is the isomer of C₂H₅OC₂H₅

You have 1 mole of a gas at STP. If you apply the ideal gas law what is the approximate volume of the gas?

goldfiish [28.3K]

Answer:

A) 22.4L

Explanation:

we know, ideal gas law states

PV=nRT

V=nRT/P

At STP,

T= 273.15K P=1atm R=0.082L.atm/mol/K n=1 mole

V=(1*0.082*273.15)/ 1

V=22.4L

Answer: The number of grams of $H_2$ in 1620 mL is 1.44 g

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = 1620 ml = 1.62 L (1L=1000ml)

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $273K$

$n=\frac{PV}{RT}$

$n=\frac{1atm\times 16.2L}{0.0821Latm/K mol\times 273K}=0.72moles$

Mass of hydrogen = $moles\times {\text {Molar mass}}=0.72mol\times 2g/mol=1.44g$

The number of grams of $H_2$ in 1620 mL is 1.44 g

Write the Iconic Bond to Metals

Nutka1998 [239]

<u>Answer:</u> The ionic compound formed is magnesium chloride having formula $MgCl_2$

<u>Explanation:</u>

Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Magnesium is the 12th element of the periodic table having electronic configuration of $1s^22s^22p^63s^2$

This element will loose 2 electrons to form $Mg^{2+}$ ion

Chlorine is the 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^{-}$ ion

So, for every 1 atom of magnesium, 2 atoms of chlorine are required. Thus, the chemical formula becomes $MgCl_2$

Hence, the ionic compound formed is magnesium chloride having formula $MgCl_2$
