The  coefficient  for hydrogen  in  the  balanced  equation   of solid  molybdenum(iV)  oxide  with gaseous  hydrogen  is  2


 Explanation

Coefficient   is defined  to  as  a number  in front   of a chemical formula in a  balanced chemical equation.

   The  reaction   of   molybdenum (iv) oxide  with  gaseous  hydrogen  is  as below,


MoO2  + 2 H2→  Mo  +2 H2O

From   balanced equation above  the coefficient   for  H2  is  2  since  the number in  front of  H2  is 2

(a) Write the dissolution reaction for solid Na2CO3 below. (Use the lowest possible coefficients. Include states-of-matter under
Andreas93 [3]

<u>Answer:</u>

<u>For a:</u> The chemical equation for the dissolution of sodium carbonate is Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)

<u>For b:</u> The net acid-base reaction is CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)

<u>Explanation:</u>

  • <u>For a:</u>

Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form aqueous solution.

The chemical equation for the dissolution of sodium carbonate follows:

Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

The chemical equation for the ionization of sodium carbonate follows:

Na_2CO_3(aq.)\rightarrow 2Na^+(aq.)+CO_3^{3-}(aq.)

  • <u>For b:</u>

Now, the anion formed which is CO_3^{2-} reacts with water to form conjugate acid.

The chemical equation for the reaction of anion with water follows:

CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)

Hence, the net acid-base reaction of the anion formed and water is written above.

If a sample containing 2.00 mL of nitroglycerin (density=1.592g/mL) is detonated, how many total moles of gas are produced?
fgiga [73]

The overall balanced chemical reaction for this is:

Detonation of Nirtoglycerin <span>
4 C3H5N3O9 --> 12 CO2 + 6 N2 + O2 + 10 H2O </span>

 

Therefore:

2.00 mL x 1.592 g/mL = 3.184 g <span>
3.184 g / 227.1 /mol = 0.0140 mol nitroglycerin 
4 moles --> 12 + 6 + 1 + 10 = 29 moles of gas 
<span>0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol) </span></span>
