OPTION D IS YOUR ANSWER.............
Answer:
2 moles of SO₂
Explanation:
Equation of reaction
H₂S + 3H₂SO₄ → 4H₂O + 4SO₂
From the equation of reaction above,
1 mole of H₂S will produce 4 moles of SO₂
1 mole of H₂S = 4 moles of SO₂
0.5moles of H₂S = zmoles of SO₂
z = (0.5*4) / 1
z = 2 moles of SO₂
0.5 moles of H₂S will produce 2 moles of SO₂
Answer:
Is the penultimate shell of the corresponding outer most atomic radius of group 14 member
***Penultimate shell is the second shell below the outer most shell which is the largest
The correct answer is the first option. The piece of evidence would suggest an unknown substance is an ionic compound is that <span>it conducts electricity when dissolved in water.</span><span> A</span><span>n ionic compound dissociates
into ions when in aqueous solution. These ions move freely in the solution and
can allow the flow of electricity into the solution.</span>
