8255 min = _?_days<br> I need help please
Ksivusya [100]

Answer:

5.733 days

Explanation:

To convert from minuets to days we must first convert minuets to hours. To do this we divide by 60 since there are 60 minuets in one hour.

8255 min ÷ 60 = 137.6 hr

Now that we have the amount of hours we can convert to days by dividing by 24 since there are 24 hours in one day.

137.6 hr ÷ 24 = 5.733 days

write a balanced net ionic equation for the following reaction: BaCl2(aq) + H2SO4 (aq) -- BaSO4(s) + HCl (aq)
Fudgin [204]

The  balanced net  equation  for

BaCl2 (aq)  + H2SO4(aq) → BaSO4(s)  + HCl  (aq)  is

 Ba^2+(aq)  +SO4^2- → BaSO4 (s)

 <u><em>Explanation</em></u>

Ionic equation  is a chemical  equation in which  electrolytes  in aqueous  solution are written as dissociated ions.

<u>ionic equation is written using the below steps</u>

Step 1:  <em>write a balanced   molecular equation</em>

 BaCl2 (aq) +H2SO4 (aq)→ BaSO4(s)  +2HCl (aq)

Step 2:   <em>Break all soluble  electrolytes  in to ions</em>

=  Ba^2+ (aq) + 2Cl^-(aq)  + 2H^+(aq) + SO4^2-(aq)→ BaSO4(s)   + 2H^+(aq)  +2Cl^- (aq)


step 3:  <em>cancel the spectator  ions  in both side of equation ( ions which  do not take place in the reaction)</em>

<em> </em><em>    =</em> 2Cl^-  and  2H^+  ions

Step 4: <em>write the final net equation</em>

<em> Ba^2+(aq)  + SO4^2-(aq)→  BaSO4(s</em><em>)</em>

A 2.36-gram sample of NaHCO3 was completely decomposed in an experiment.
enyata [817]

Answer:

Explanation:

a) The mass of the reactants is 2.36 grams, and the mass of the products is 1.57 grams plus the mass of the carbonic acid. Thus, using the law of conservation of mass, we get the mass of the carbonic acid is 2.36 - 1.57 =  0.79 grams.

b) The gram-formula mass of sodium bicarbonate is 84.006 g/mol, meaning that 2.36/84.006 = 0.028 moles were consumed. Thus, this means that in theory, 0.014 moles of carbonic acid should have been produced, which would have a mass of (0.014)(62.024)=0.868 grams. Thus, the percentage yield is (0.79)/(0.868) * 100 = 91%
