How many moles of the Htion in 395 mL of 1.325 M sulfuric acid (H2SO4).
Irina18 [472]

Answer:

1.05 mol

Explanation:

Step 1: Given data

  • Molarity of sulfuric acid (M): 1.325 M (1.325 mol/L)
  • Volume of solution (V): 395 mL (0.395 L)

Step 2: Calculate the moles of sulfuric acid (n)

We will use the following expression.

M = n/V

n = M × V

n = 1.325 mol/L × 0.395 L = 0.523 mol

Step 3: Calculate the moles of H⁺

H₂SO₄ dissociates completely according to the following equation.

H₂SO₄ ⇒ 2 H⁺ + SO₄²⁻

The molar ratio of H₂SO₄ to H⁺ is 1:2. The moles of H⁺ are 2/1 × 0.523 mol = 1.05 mol.

Please help balance this equation <br> _B2Br6 + _HNO3= _B(NO3)3+_HBr
Trava [24]

Answer: B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH

Equation

B2Br6+HNO3=B(NO3)3+HBr

B=2                                 B=1

BR=6                             BR=1

H=1                                  H=1

N=1                                  N=3

O=3                                 O=9

ANSWER

B2Br6 + 6HNO3 → 2B(NO3)3 + 6BrH

B=2                                 B=2

BR=6                             BR=6

H=6                                  H=6

N=6                                  N=6

O=18                                 O=18
