What distinguishes effusion from diffision? How are these processes similar?
zvonat [6]

Answer:

In effusion, a substance escapes through a tiny pinhole, or other hole whereas diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

Explanation:

According to effusion, if there is a small hole in a container, a gas will leak from it. So, in this process a substance escapes through a tiny pinhole, or other hole.

According to diffusion, the two solutions will reach the lowest possible concentration of both, if they are combined and not mixed. So, diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

Combustion analysis of toluene, a common organic solvent, gives 8.20 mg of co2 and 1.92 mg of h2o. if the compound contains only
cestrela7 [59]
For the purpose of proper representation in this item, we let the number of moles of carbon in the compound be x, that of H is y. The equation of toluene now becomes,
                   CxHy
The combustion reaction is,
        CxHy + O2 --> CO2 + H2O

The equation presented above may not be balanced yet. Then, we determine the number of mmols of C, H, and O in the product using the given masses.
    
(1) 8.20 mg CO2
             (8.2 mg CO2)(1 mmol CO2/44 mg CO2) = 0.186 mmol CO2
     which means,
                     0.186 mmol C
                     0.373 mmol O

(2) 1.92 mg H2O
            (1.92 mg H2O)(1 mmol H2O/18 mg H2O) = 0.107 mmol H2O
    which means
                    0.2133 mmol H
                    0.107 mmol O

Thus, the equation for toluene is,
               C(0.186)H(0.2133)

Dividing the numbers by the lesser value,
               CH(8/7)
To eliminate the fraction, we multiply by the denominator. Thus, the final answer would be,
             <em> C7H8</em>

Nick needs 3.5 moles of sodium fluoride (NaF) for a solution he is mixing in the lab. How many grams of NaF does Nick need to me
Minchanka [31]

Answer:

147 g

Explanation:

<em>The number of moles of a substance is the ratio of the mass of the substance and the molar mass of that substance.</em> Mathematically,

  mole = mass of substance/molar mass

In this case, Nick needs 3.5 moles of NaF, the molar mass of NaF is calculated as:

  23 + 19 = 42 g/mol (Note: Na = 23, F = 19)

Hence,

mass of 3.5 mole NaF = mole x molar mass

                              = 3.5 x 42 = 147 g.

<em>Hence, Nick would need to measure out </em><em>147 g</em><em> NaF using a suitable weighing balance.</em>

If 2 molecules of one reactant combine with 3 molecules of another to produce 5 molecules of a product, then what is the represe
zhenek [66]

Answer:- 2A+3B\rightarrow 5C

Explanations:- Let's say the first molecule is A and the second molecule is B and the product molecule is C.

From given information, 2 molecules of A react with 3 molecules of B to produce 5 molecules of C.

We write the reactants on left side and the product on right side and there is an arrow between them from reactants towards the products.

So, the reaction could be represented as:

2A+3B\rightarrow 5C
