Each step in the following process has a yield of 90.0 %. ch 4 + 4 cl 2 ⟶ ccl 4 + 4 hcl ccl 4 + 2 hf ⟶ ccl 2 f 2 + 2 hcl the ccl 4 formed in the first step is used as a reactant in the second step. if 3.00 mol ch 4 reacts, what is the total amount of hcl produced? assume that cl 2 and hf are present in excess.

4.86 moles of HCl

Explanation:

1. First write the balanced chemical equations involved in the process:

2. Calculate what amount of is formed in the first reaction.

As the yield of each reaction is 90.0%, the amount of produced is the following:

3. Calculate the amount of HCl produced.

The total amount of HCl produced with a 90.0% yield is:

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
