Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction turns out:

In such a way, by means of the mass of law action for such reaction, which is given below:

And in terms of the change
due to reaction extent:

results:

In such a way, Kp:

Nonetheless, K is asked instead of Kp, thus:

Whereas:

Which is the change in the moles of gaseous species chlorine and carbon tetrachloride. Hence, we finally obtain:

What is density?</h3>
- Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass).
- Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.
Given,
The density of ethanol, C2H5OH = 0.789 g/mL


= 7.843 g

Therefore, the answer is 9.94 ml

<u>The complete question is -</u>
If the density of ethanol, C2H5OH, is 0.789 g/mL. How many milliliters of ethanol are needed to produce 15.0 g of CO2 according to the following chemical equation?
C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l)
Valence electrons in NH2Cl:
=1(5)*2(1)*1(7)
=14
So there are 14 valence electrons in NH2Cl
As each stick represents an valence electron pair.
And there are 14 valence electrons, so there can be 7 valence electron pairs.
And for 7 valence electron pairs, 7 sticks needed.
Answer:
Moles: 
Molar mass: 
Explanation:
Hello,
In this case, we can use the ideal gas equation to compute the moles of the gas sample as shown below:

Thus, we should use the pressure in atm as follows:

Moreover, the molar mass is obtained by dividing the given mass by the obtained moles:
