Provide an example of unit conversion utilizing the process of dimensional analysis​
Vera_Pavlovna [14]

Answer:

See below

Explanation:

1 year is how many seconds ?

1 year :

   365 days/ yr   *   24 hours / day  *  60 min/ hour * 60 seconds/ min

      =====  

see how the  'days'  'hours'  'min'    all cancel and you are left with

   'seconds'  / 'year'   ?      = 31 536 000 seconds/year

For the reaction C6H6 + ? O2 → ? CO2+? H2O , what is the maximum amount of CO2 which could be formed from 6.59 g of C6H6 and 6.6
Likurg_2 [28]

Answer: 3.52 grams

Explanation:

2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O

Given moles:

moles of oxygen = 6.62

moles of C_6H_6=\frac{\text {given mass}}{\text {molar mas}}=\frac{6.59g}{78g/mol}=0.08moles

According to stoichiometry:

2 moles of benzene reacts with = 15 moles of oxygen

Thus 0.08 moles of benzene will react with = \frac{15}{2}\times 0.08=0.6 moles of oxygen

Thus benzene is the limiting reagent as it limits the formation of products and oxygen is the excess reagent.

As 2 moles of benzene produce = 12 moles of carbon dioxide

0.08 mole of benzene will produce =\frac{12}{2}\times 0.08=0.48moles of carbon dioxide

Mass of carbon dioxide=moles\times {\text {Molar mass}}=0.48\times 44=3.52g

Thus 3.52 g of carbon dioxide are produced.

need help plz !The reaction between hydrogen and nitrogen to give ammonium is a reversible reaction. if why or why not.Answer it
MaRussiya [10]

Answer:

We get ammonia because the forward and reverse reactions are happening at the same rates.

If 3 mol of  

H

2

is mixed in a sealed vessel with 1 mol  

N

2

under suitable conditions then they will react to form ammonia  

N

H

3

:

N

2

+

3

H

2

→

2

N

H

3

At the start of the reaction the concentration of the  

N

2

and  

H

2

are high. As soon as some  

N

H

3

is formed the reverse reaction will start to occur:

2

N

H

3

→

N

2

+

3

H

2

The rate of the reaction depends on concentration so the forward reaction will be fast at first when the concentration of the reactants is high. It will slow down as their concentration decreases.

By the same reasoning the reverse reaction will be slow at first then increase. These two processes continue until a point is reached when the rates of the forward and reverse reactions are equal.

We now state that the reaction has reached equilibrium which we show by:

N

2

+

3

H

2

⇌

2

N

H

3

It is described as "dynamic" because the forward and reverse reactions are happening at the same time although the concentrations of all the species remain constant.

So although  

N

H

3

is constantly breaking down, more is being formed at a constant rate.

In the Haber Process the system is actually not allowed to completely reach equilibrium as the process is continuous, as described in Mukhtar's answer.
