Pretty sure it’s 0.39 moles
KonstantinChe [14]2 years ago
7 0

Answer:

0.39 moles

Explanation:

To find how many moles are in 50.0 g of CaC₂O₄ you divide the grams of the sample by the molar mass of the compound;

\frac{50.0 g}{128.097 g/mol}=0.39 mol

The grams cancel out and you are left with moles!

I hope this help ^-^

What mass of calcium chloride is produced from 5.59 mol of hydrochloric acid
svp [43]

From the mole ratio of the reaction as given in the equation of the reaction, the mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is 310.245 g.

<h3>What mass of calcium chloride can be produced from 5.59 mol of hydrochloric acid?</h3>

The mass of calcium chloride that can be produced from 5.59 mol of hydrochloric acid is determined from the equation of the reaction.

The equation of the reaction is given below:

Ca²⁺ (aq) + 2 HCl (aq) ---> CaCl₂ (s) + H₂ (g)

From the equation of the reaction, the mole ratio of HCL and calcium chloride is 2 : 1

Therefore, moles of calcium chloride that can be produced will be:

The moles of calcium chloride = 5.59 moles * 1/2

The moles of calcium chloride = 2.795 moles

The mass of calcium chloride produced = moles * molar mass

Molar mass of calcium chloride = 111 g/mol

Mass of calcium chloride produced = 2.795 * 111

Mass of calcium chloride produced = 310.245 g

How many unpaired electrons would you expect on iron in [fe(h2o6] 3+?
MrMuchimi
The iron (III) has 5 valence electrons and the complex is in a octahedral geometry. Since water as a ligand has a small splitting energy, the complex will be a high spin and all of the five electrons will be unpaired.

What kind of intermolecular forces act between a hydrogen cyanide molecule and a potassium cation?
andriy [413]

Answer:

ion-dipole

Explanation:

Let us remember that the potassium cation is an ion, a positive ion to be precise.

There is a dipole existing in the hydrogen cyanide molecule. The positive end of the dipole is on hydrogen while the negative end of the dipole is on the cyanide moiety.

The only possible interaction between the potassium cation and the hydrogen cyanide is an ion dipole interaction. The cation interacts with the cyanide moiety having a partial negative charge in the molecule.
