Calculate how many moles of water molecules were produced in the combustion of ethanol in oxygen.
nadya68 [22]

There  are 3 moles of water formed in the complete combustion of ethane.

<h3>What is Combustion Reaction? </h3>

Combustion is a chemical reaction between substances , usually including oxygen and usually accompanied by the generation of heat and light in form of flame.

For example , the wood burning in a fireplace. The wood is a fuel which continuously react with oxygen in the air in a combustion reaction.

When ethane goes for combustion

reaction ,

C2H6+7/2 O2→2CO2+ 3H2O

As you can see on the above reaction 3 moles of water molecules are produced .

Iron(II) can be oxidized by an acidic K2Cr2O7 solution according to the net ionic equation: Cr2O72− + 6Fe2+ + 14H+ → 2Cr3+ + 6Fe
cestrela7 [59]

Answer:

The molar concentration of Fe²⁺ in the original solution is 1.33 molar

Explanation:

Moles of K₂Cr₂O₇ = Molarity x Volume (lit)

                             = 0.025 x 35.5 x 10⁻³

                             = 0.0008875

Cr₂O₇²⁻ + 6 Fe²⁺ + 14 H⁺ → 2 Cr³⁺ + 6 Fe³⁺ + 7 H₂O

From equation

              1 mole K₂Cr₂O₇ used for the oxidation of 6 moles Fe²

0.0008875 mole K₂Cr₂O₇ used for the oxidation of =\frac{6 X 0.0008875}{1} = 0.005325 mole of  Fe²

      Molarity = \frac{No. of moles of solute}{Volume     of solution(lit)}

Molar concentration of  Fe² = \frac{0.005325 X 1000}{25} = 1.33 molar

So molar concentration of Fe²⁺ in the original solution = 1.33 molar

If a sample of 0.362 m lithium phosphate contains 0.284 g of lithium, what is the volume of the sample?
fenix001 [56]
From the periodic table:
mass of lithium = 6.941 grams
number of moles = mass / molar mass
number of moles of Li = 0.284 / 6.941 = 0.0409 moles

Molarity can be calculated using the following rule:
molarity = number of moles of solute / liters of solution
volume (in liters) = number of moles of solute / molarity
volume = 0.0409 / 0.362 = 0.1129 liters
