Write the net ionic equation for the following molecular equation Mg (s) +Snso (aq) Mgso4 (aq) Sn(s) Use the lowest possible coe
Simora [160]

Answer:

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

Explanation:

Let's consider the following molecular equation.

Mg(s) + SnSO₄(aq) ⇄ MgSO₄(aq) + Sn(s)

The full ionic equation includes al the ions and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) + SO₄²⁻(aq) ⇄ Mg²⁺(aq) + SO₄²⁻(aq) + Sn(s)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution
Ganezh [65]

Answer:

0.01932 L

Explanation:

First we <u>convert 105 mM to M</u>:

  • 105 mM / 1000 = 0.105 M

Next we <u>convert 552 mL to L</u>:

  • 552 mL / 1000 = 0.552 L

Then we use the following equation:

  • C₁V₁=C₂V₂

Where:

  • C₁ = 3 M
  • V₁ = ?
  • C₂ = 0.105 M
  • V₂ = 0.552 L

We<u> input the given data</u>:

  • 3 M * V₁ = 0.105 M * 0.552 L

And <u>solve for V₁</u>:

  • V₁ = 0.01932 L

A sample of an ideal gas has a mass of 0.311 grams. its volume is 0.225 l at a temperature of 55oc and a pressure of 1.166 atm.
BabaBlast [244]
Use pv=nrT


where p is the pressure,
v is the volume,
n is the number of mole (which can be equal to mass /mr),
T is the temperature in kelvin,
and r is (molar constant) = 8.31 (units)
