The exhaust gas from an automobile contains 1.5 percent by volume of carbon monoxide. What is the concentration of CO in mg/m' a
FrozenT [24]

Answer:

(a) 17,178 mg/m3

(b) 11,625 mg/m3

Explanation:

The concentration of CO in mg/m3 can be calculated as

C (mg/m3) =(P/RT)*MW*C_{ppm}

For standard conditions (1 atm and 25°C), P/RT is 0.0409.

Concentration of 1.5% percent by volume of CO is equivalent to 1.5*10,000 ppm= 15,000 ppm CO.

The molecular weigth of CO is 28 g/mol.

(1) For 25°C and 1 atm conditions

C=(P/RT)*MW*C_{ppm}\\\\C=0.0409*28*15,000=17,178

(b) For 200°C and 1.1 atm,

P/RT=0.0409*(P/P_{std})*(T_{std}/T)\\P/RT=0.0409*(1.1atm/1atm)*(273+15K/273+200K)=0.0277

Then the concentration in mg/m3 is

C=(P/RT)*MW*C_{ppm}\\\\C=0.0277*28*15,000=11,625

What is the empirical formula of ascorbic acid, given that the pseudoformula is C3.407 H4.53 O3.406??
Tom [10]
To determine the empirical formula of ascorbic acid, we divide the lowest fraction with the other values. For this case, we divide everything with 3.406. We do as follows:

C = 3.407 / 3.406 = 1
H = 4.53 / 3.406 = 1.33
O = 3.406 / 3.406 = 1

So, you have CHO

Hope this answers the question. Have a nice day.

Define ionic bond and explain the formation of nacl and mgo
fomenos

a.

Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.

The atom that loses the valence electron is called the electron donor while the atom that accepts the electron is called the electron acceptor.

Ionic bond usually occurs between metals and non metals.

Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.

b.

The force of attraction between Na⁺ and Cl⁻ forms the ionic bond.

  • In the formation of NaCl, Na has one valence electron in its outermost shell and Cl needs one electron to complete the stable octet configuration.
  • Na donates its valence electron to Cl to form the ionic bond. So, the Na atom becomes positively charged with a charge of +1 while the Cl atom becomes negatively charged with a charge of -1.

Since the atoms are now charged, the force of attraction between them forms the ionic bond.

c.

The force of attraction between Mg²⁺ and O²⁻ forms the ionic bond.

  • In the formation of MgO, Mg has two valence electrons in its outermost shell and O needs two electrons to complete the stable octet configuration.
  • Mg donates its two valence electron to O to form the ionic bond. So, the Mg atom becomes positively charged with a charge of +2 while the O atom becomes negatively charged with a charge of -2.

Since the atoms are now charged, the force of attraction between them forms the ionic bond.
