Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:
Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water.
or we can add H2SO4 to produce:
Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. <span />
Answer:
B
Explanation:
Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. ... In this case, the products, or final state, have more free energy than the reactants, or initial state. Endergonic reactions are non-spontaneous, meaning that energy must be added before they can proceed.
If you count the methionine expressed for the start codon as part of the precursor protein, then (81+1)*3. (The start codon is expressed, but the stop codon isn't.)
Answer:
The theoretical yield of urea = <u>120.35kg</u>
The percent yield for the reaction = <u>72.70%</u>
Explanation:
Lets calculate -
The given reaction is -
→
Molar mass of urea
= 60g/mole
Moles of
=
(since
)
= 4011.76 moles
Moles of
= 
= 
= 2386.36 moles
Theoritically , moles of
required = double the moles of 
but ,
, the limiting reagent is 
Theoritical moles of urea obtained = 
= 
Mass of 2005.88 mole of
=
= 120352.8g

= 120.35kg
Therefore , theroritical yeild of urea = 120.35kg
Now , Percent yeild = 
72.70%
Thus , the percent yeild for the reaction is 72.70%
Sodium reacts with chlorine to form Na+ ions and Cl- ions in spite of the fact that the first ionization energy of sodium is larger than the electron affinity of chlorine. To explain this, we need to divide the reaction between sodium and chlorine
