Answer:

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

Explanation:

Step 1: Write out unbalanced reaction

Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Step 2: Balance

We need the same number of SO₄²⁻ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O

Now we need the same amount of H⁺ on each side

Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O

The impact of fossil fuel combustion on the global carbon cycle

olga_2 [115]

When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.

If you dilute 18.8 mL of a 3.5 M solution to make 296.6 mL of solution, what is the molarity of the dilute solution?

hodyreva [135]

Answer:

0.22M

Explanation:

We will be using the law of dilutions. We are simply increasing the amount of solvent to create a larger volume of solution.

So: moles before dilution = moles after dilution & $moles_{concentrated} = moles_{dilute}$ . And M = moles/liter of solution, so if we express this as moles = M x $L_{soln}$ .

That is how we derive the formula we will be using: $M_{concentrated} * Vol_{conc} = M_{dilute} * Vol_{dilute}$

$M_{1} * Vol_{1} = M_{2} * Vol_{2}$

Applying this formula to our problem, we can substitute the variables with the given values to find the molarity of the dilute solution.

M1 = 3.5M

V1 = 18.8mL

M2 = ?

V2 = 296.6mL

Equation: (3.5M)(18.8mL) = (296.6mL)(M2)

==> 65.8M*mL = 296.6mL * M2

==> M2 = (65.8 M*mL)/296.6mL

==> M2 = 0.22M

Would you expect hydrogen chloride to be a gas, a liquid or a solid, at room temperature and pressure? Explain your answer

Vlada [557]

At room temperature hydrogen chloride is a colorless gas with a sharp or pungent odor. Under pressure or at temperatures below –85°C (-121°F), it is a clear liquid.
