Upon balancing the equation below, how many moles of sulfuric acid are needed to react completely with 6.4 moles of lithium hydr
elena-14-01-66 [18.8K]

Moles of Sulfuric acid needed to react completely : 3.2

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction (balanced)

<em>H₂SO₄ (aq) + 2 LiOH (aq) ⇒ Li₂SO₄ (aq) + 2 H₂O (l)</em>

moles of LiOH = 6.4

From equation, mol ratio of H₂SO₄ : LiOH = 1 : 2, so mol H₂SO₄ :

\tt mol=\dfrac{1}{2}\times 6.4=3.2

A 250 gram sample of water at the boiling point had 45.0 kj of heat added. how many grams of water were vaporized? heat of vapor
Julli [10]
You have 45 kJ of heat added and for every 40.6 kJ added, one mole is able to be vaporized. Find how many moles you can vaporize.

45 kJ / 40.6 kJ = 1.1 moles

Water is roughly 18 g per mole so 1.1 moles x 18 g per mol = 19.95 grams vaporized

Hope I helped!

4. Balance the following chemical equation. Say what the coefficients "a"
lisabon 2012 [21]

Answer:

a = 4

b = 3

Explanation:

<u>SOLUTION :-</u>

Balance it by using 'hit & trial' method , and you'll get the answer :-

2Fe₂O + 3C → <u>4</u>Fe + <u>3</u>CO₂

⇒ a = 4 ; b = 3

<u></u>

<u>VERIFICATION :-</u>

<em>In reactant side of equation :-</em>

  • Number of atoms in Fe = 2×2 = 4
  • Number of atoms in O = 2×3 = 6
  • Number of atoms in C = 3×1 = 3

<em>In product side of equation :-</em>

  • Number of atoms in Fe = 4×1 = 4
  • Number of atoms in C = 3×1 = 3
  • Number of atoms in O = 3×2 = 6

Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
