Answer:

The last question is not complete. This is the possible question " How many atom of oxygen and hydrogen is in water molecule"?

The answers are:

1)    1 proton

2)   8 Neutrons

3)   1 Electrons

4)   2 electrons

5)   Ionic bond

6)   6 Electrons

7)   Inner or S orbit

8)   2 atoms of hydrogen and one atom of oxygen

Explanation:

Atomic number is the number of proton in the nucleus of an atom.

The proton number is equal to the number of electron of an atom.

The formula: mass number = proton number + neutron number  is used to calculate either the proton number or the neutron number of an atom.

The K shell contains 2 electrons in it's shell. The L shell contains 8 electron and the M shell also contains 8. Oxygen has 6 electrons in it's outermost shell while hydrogen has only one.

Ionic bond involves the sharing of electrons between two atoms bearing a negative and a positive charge. It exist between hydrogen and oxygen atom.

The decomposition of N2O to N2 and O2 is a first-order reaction. At 730°C, the rate constant of the reaction is 1.94 × 10-4 min-
grin007 [14]

Answer:

Total pressure 5.875 atm

Explanation:

The equation for above decomposition is

2N_2O \rightarrow 2N_2 + O_2

rate constant k =  1.94\times 10^{-4} min^{-1}

Half life t_{1/2} = \frac{0.693}{k} = 3572 min

Initial pressure N_2 O = 4.70 atm

Pressure after 3572 min = P

According to first order kinematics

k = \frac{1}{t} ln\frac{4.70}{P}

1.94\times 10^{-4} = \frac{1}{3572} \frac{4.70}{P}

solving for P we get

P = 2.35 atm

2N_2O \rightarrow 2N_2 + O_2

initial           4.70                         0             0

change        -2x                          +2x           +x

final             4.70 -2x                     2x           x

pressure ofO_2 after first half life  = 2.35 = 4.70 - 2x

                                                          x = 1.175

pressure of N_2 after first half life  =  2x = 2(1.175) = 2.35 ATM

Total pressure  = 2.35 + 2.35 + 1.175

                          = 5.875 atm

C3H8 + 5O2 → 3CO2 + 4H2O
trasher [3.6K]

Answer:

16.5moles of CO2

Explanation:

Molar mass of O2 is 32g/Mol

No of mole = 880/32 = 27.5 moles

27.5 Mol of O2 gives X mole of CO2

5 mole of O2 gives 3 moles of CO2

No of mole of CO2 = (27.5×3)/ 5 = 16.5moles
