If I start with 5 grams of c3h8 what is my theoretical yield of water

Chemistry

Triss [41]2 years ago

C3H8  (propane) undergoes   combustion  to   produce  water  and  carbon (IV)  oxide  according  to   equation   below
C3H8(g)  +  5 O2(g)  ---->  3 CO2(g)  +  4 H2O(l)

calculate  the  moles  of  C3H8  used
mole =  mass/molar  mass
molar  mass  of  C3H8  = ( 12x3  )+(  1  x  8)=44  g/mol
moles  of  C3H8=  5g/  44 g/mol=  0.114  moles
by  use    of  mole  ratio  between  C3H8  to H2O   which  is  1:4  therefore  the  mole  of  water=  0.114  x4=0.456  moles
mass  of  water  =moles  of  water  x molar  mass  of  water

that  is  0.456 moles  x  18g/mol  = 8.208  grams

Answer:

A = solid

B = liquid

C = plasma

D = gas

Explanation:

A= Particles vibrate in a rigid structure and do not move relative to their neighbors.

It is the property of solid.

Properties of solids:

Solids have definite volume and shape.

In solids molecules are tightly pack and very close to each other.

Their melting and boiling point are every high.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.

B = it takes the shape of its container but keeps a constant volume.

it is the property of liquid.

Properties of Liquid:

Liquid have definite volume but don,t have definite shape.

Their densities are high as compared to the gases but low as compared to the solids.

In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.

C = It is the most common sate of matter in universe.

It is the property of plasma

Plasma

" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"

The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.

It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.

D = particles moves rapidly and independent of other particles.

It is the property of gas.

Properties of gases:

Molecule of gases randomly move everywhere and occupy all available space.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.

Their densities are very low as compared to the liquid and solids.

Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.

The very weak inter molecular forces are present between gas molecules.

What is the oxidation number of Nitrogen in HNO2? <br><br> +1<br> -1<br> +3<br> -3
WITCHER [35]
I believe the correct answer from the choices listed above is the third option. The <span>oxidation number of Nitrogen in HNO2 would be +3. It is calculated as follows:

1 + x + (-2)(2) = 0
x = +3

Hope this answers the question. Have a nice day.</span>
