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>

What is an indicator? What does it tell you about solutions?
Sophie [7]

Answer:

Explanation:

The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.

\al(s) + 3agno3(aq) → al(no3)3(aq) + 3ag(s) this equation represents which type of chemical reaction?
Savatey [412]
 Al(s)  + 2AgNO3(aq) = Al(NO3)3(aq) + 3 Ag (s) 


is a  single  replacement reaction

 A  single  replacement  reaction  is a type  of chemical reaction were element react with a compound  and  the element take  place  of another element in that  compound.  In the reaction above Aluminium  (Al) take the place of  silver (Ag)  from it compound.that is AgNO3. single  replacement reaction is possible because  aluminium   is  in high in reactivity   series    as compared to silver.
