the reaction of 50 mL of gas with 50 mL of gas via the equation: Cl2(g) + C2H4(g) ➔ C2H4Cl2 (g) will produce a total of ________

spin [16.1K]

Explanation:

The given data is as follows.

50 ml of $Cl_{2}$ , 50 ml of $C_{2}H_{4}$

And, it is known that at STP 1 mole of a gas occupies 22.4 L. Hence, moles present in 50 ml of gas are as follows.

$\frac{50}{22.4 \times 1000}$ (As 1 L = 1000 ml)

= $2.23 \times 10^{-3}$ moles

So, according to the given equation $2.23 \times 10^{-3}$ moles of $Cl_{2}$ reacts with $2.23 \times 10^{-3}$ moles of $C_{2}H_{4}$ .

Hence, moles of $C_{2}H_{4}Cl_{2}$ is equal to the moles of $C_{2}H_{4}$ and $Cl_{2}$ .

Therefore, moles of $C_{2}H_{4}Cl_{2}$ = $2.23 \times 10^{-3}$ moles

1 mole of $C_{2}H_{4}Cl_{2}$ = 22.4 L

$2.23 \times 10^{-3}$ moles = $22.4 \times 2.23 \times 10^{-3} moles$

= 50 ml of product

Thus, we can conclude that 50 ml of products if pressure and temperature are kept constant.

How does Silicon shape our technological reality

Ymorist [56]

Silicon shapes our technological reality because computer chips are made out of silicon. Different computer parts, are made out of silicon chips, tablets, phones, different electronic devices, everything has some silicon in them. Without silicon we would (currently) not have any of those. That is how silicon shapes our technological reality :)

0.509g sample pure platinumetal was reacted with HCl to firm O.889g of platinum and chlorine. what is the percent by mass of pla

stepan [7]

Platinum plus chlorine equals 0.889 grams whereas the platinum alone is 0.509grams so 0.509/0.889grams = 57% of the mass of the platinum plus chlorine. The chlorine would be 0.889-0.509=0.38 grams. The chlorine would make up about 42.7% of the total mass in grams.
