 <span>H2SO4 gives 2 moles oh H+ per mole of acid 

[H2SO4] = 2M so [H+] = 4M 

pH = -log(4) = -.6 

Therefore, the pH </span><span>of a 2.0 M H2SO4 solution is -0.6

Answer:The pH of the solution -0.60 .The pH scales ranges value from 1 to 14.So, the given pH of the solution is coming out to negative which means that in a lab preparation of solution with this pH is not feasible.

Explanation:

The pH of the solution defined as negative logarithm of [H^+] ion concentration.

H_2SO_4(aq)\rightarrow 2H^+(aq)+SO_4^{2-}(aq)

According to reaction 1 moles of sulfuric acid gives 2 moles of H^+

Then 2 mol /L solution of sulfuric acid will give = 4 mol/L of H^+ ions.

pH=-\log[H^+]=-\log[4.0]=-0.60

The pH scales ranges value from 1 to 14.So, the given pH of the solution is coming out to negative which means that in a lab preparation of solution with this pH is not feasible.

I need to make up an experiment !! Please help

Question: Baking a Cake Without Flour.

Hypothesis: I think that when I remove the flour from the standard cake recipe, I'll end up with a flat but tasty cake.

Procedure: I baked two cakes during my experiment. For my control, I baked a cake following a normal recipe. I used the Double Fudge Cake recipe on page 292 of the Betty Crocker Cookbook. For my experimental cake, I followed the same recipe but left out the flour. I first obtained a 2-quart mixing bowl.  

Results: My control cake, which I cooked for 25 minutes, measured 4 cm high.  Eight out of ten tasters that I picked at random from the class found it to be an acceptable dessert. After 25 minutes of baking, my experimental cake was 1.5 cm high and all ten tasters refused to eat it because it was burnt to a crisp.

What did I learn?/Conclusion: Since the experimental cake burned, my results did not support my hypothesis.  I think that the cake burned because it had less mass, but cooked for the same amount of time.  I propose that the baking time be shortened in subsequent trials.

Which internal system is responsible for transporting oxygen and nutrients through an animal's body?
katen-ka-za [31]

Answer:

B: circulatory system

Explanation:

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
