Concentrated  sulfuric  acid  is  used    to promote  acid  catalyzed  dehydration  because  it  has   little  water.This favor the  forward  reaction.sulfuric  acid  acts  as  as  proton  source  to  enable  loss  of  leaving  group  in  forward  reaction  and electrophile  addition  in  reverse  reaction.

Given the equation: HCl + Na2SO4 → NaCl + H2SO4, if you start with 8 moles of hydrochloric acid, how many grams of sulfuric acid
Simora [160]

Answer:

392g sulfuric acid are produced

Explanation:

Based on the balanced equation:

2HCl + Na2SO4 → 2NaCl + H2SO4

<em>2 moles of HCl produce 1 mole of sulfuric acid</em>

<em />

To solve the problem we need to find the moles of sulfuric acid produced based on the chemical equation. Then, using its molar mass -<em>Molar mass H2SO4 = 98g/mol- </em>we can find the mass of sulfuric acid produced:

<em>Moles sulfuric acid:</em>

8mol HCl * (1mol H2SO4 / 2mol HCl) = 4 mol H2SO4

<em>Mass sulfuric acid:</em>

4mol H2SO4 * (98g / mol) =

392g sulfuric acid are produced

1,5,25,125 what’s the pattern rule and extend by 3 more numbers
nika2105 [10]

For the first one the pattern is multiply the previous number by five as you see 1 x 5 = 5 and so on. To keep adding to it you would do

125 x 5 = 625     625 x 5 = 3125    3125 x 5 = 15625

Now for the second one the pattern is divide the previous number by three as you can see 2187 / 3 = 729 and so on. To keep going you would

81 / 3 = 27       27 / 3 = 9        9 / 3 = 3

I hope this helps you and if you have anymore questions i'll be  glad to answer them.
