The balanced reaction that describes reaction of ethylene and oxygen to produce carbon dioxide and water is expressed C2H2(g) + 5/2 O2 (g) = 2cO2 (g)+ h2O(g). We convert first the given data to moles thru PV=nRT. The number of moles of oxygen is 0.6349 moles. One mole of c2h2 reacts with 2.5 moles oxygen. The answer is 0.2539 moles c2h2.

A sample of oxygen gas occupies 3.60 liters at a pressure of 1.00 atm. If the temperature is held constant, what will be the vol
zzz [600]
<h3><u>Answer</u>;</h3>

= 1.44 L

<h3><u>Explanation</u>;</h3>

Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.

Mathematically;

<em>P α 1/V</em>

<em>PV =constant </em>

<em>Thus, P1V1 = P2V2 </em>

<em>P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm</em>

<em>V2 = P1V1/P2</em>

<em>     = (1× 3.6)/2.5 </em>

<em>     = </em><u><em>1.44 L</em></u>

In a voltaic cell based on the Cu-Zn reaction
nata0808 [166]

Answer:

The quantities of electrical charge that are they can produce are the same

Explanation:

The quantity of electrical charge produced by an electrochemical cell is given by

Number of moles of electrons × Faraday's constant.

since the number of moles of electrons involved in the two electrochemical reactions are the same (2 moles of electrons each) then the charge that they can produce will also be the same.

Hence the answer.
