If 8cm^3 of H2 reacts with an excess of Cl2, calculate how much of the HCL(g) is produced.
Rom4ik [11]
First, we need the balanced equation: H₂ + Cl₂ ---> 2HCl

since not much information is given, I am assuming we are at STP and that 22.4 Liters= 1 mol

1) let's convert the volume to moles using the molar volume of a gas. also we need to convert the cm₃ to mL, then to Liters.

8 cm³ (1 ml/ 1 cm³)(1 L/ 1000 mL) (1 mol/ 22.4 Liters)= 3.6x10⁻⁴ moles of H₂

2) let's use the mole ratio of the balanced equation to convert moles of H₂ to moles of HCl

3.6x10⁻⁴ mol H₂ (2 mol HCl/ 1 mol H₂)= 7.1x10⁻⁴ mol HCl

3) lastly, we convert the moles of HCl to grams using the molar mass.

molar mass of HCl= 1.01 + 35.5= 36.51 g/mol

7.1x10⁻⁴ mol HCl (36.51 g/mol)=<span> 0.026 grams HCl</span>

Which is a positive effect of the technology advance of going from a compass to a gps
egoroff_w [7]

Answer:

Compass - Gps                              

Explanation:

I belive the pro's                                      and cons are

                                         GPS             you are trusting a little man made device

the direction you                               to give you directions

are going on                                        and that it won't break or die

a device not a paper map

                                                Compass

You can see north east south and              it is usually carefully crafted for                                                                                                                                                                          o                                                                     outdoors but it has no roads and

west on the compass and                          if given no directions, extremely

you can see the roads follow directions                  confusing until you learn it

like go south then east.

If the temperature on 244 mL of a gas is changed to 488 mL and 6 atm, at constant
Fittoniya [83]

Answer:

<h2>12 atm</h2>

Explanation:

To find the initial pressure we use the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the initial pressure

P_1 =  \frac{P_2V_2}{V_1}  \\

From the question we have

P_1 =  \frac{488 \times 6}{244}  =  \frac{2928}{244}  \\

We have the final answer as

<h3>12 atm</h3>

Hope this helps you

you are given a solution of lead nitrate. use any of the solution used in this experiment to form a white precipitate of lead ch
Vesnalui [34]

We have as a reagent a salt, lead nitrate (Pb(NO3)2), and an unknown solution that gives us as a product lead chloride (PbCl2). That is, the solution must contain chlorine.

If a chlorine solution is used we will have the following reaction:

Pb(NO_{3)2}+2Cl^-\rightarrow PbCl_2+2NO^-_3

So, with a chlorine solution, we will have a white precipitate of lead chloride.
