Explanation:

<h3>in H2SO5 two oxygen atoms are in -1 oxidation state.</h3>

The Oxidation number of S sulphur is +6.

This is because there is a peroxide link in the molecule.

In the laboratory you dissolve 13.9 g of potassium phosphatein a volumetric flask and add water to a total volume of 250mL.

tensa zangetsu [6.8K]

Answer:

Molarity of the solution? 0,262 M.

Concentration of the potassium cation? 0,786 M.

Concentration of the phosphate anion? 0,262 M.

Explanation:

Potassium phosphate (K₃PO₄; 212,27 g/mol) dissolves in water thus:

K₃PO₄ → 3 K⁺ + PO₄³⁻ <em>(1)</em>

Molarity is an unit of chemical concentration given in moles of solute (K₃PO₄) per liters of solution.

There are 250 mL of solution≡0,25 L

The moles of K₃PO₄ are:

13,9 g of K₃PO₄ × $\frac{1mol}{212,27 g}$ = 0,0655 moles of K₃PO₄

The molarity of the solution is:

$\frac{0,0655 moles}{0,25L}$ = 0,262 M

In (1) you can see that 1 mole of K₃PO₄ produces 3 moles of potassium cation. The moles of potassium cation are:

0,0655 moles×3 = 0,1965 moles

The concentration is:

$\frac{0,1965 moles}{0,25L}$ = 0,786 M

The moles of K₃PO₄ are the same than moles of PO₄³⁻, thus, concentration of phosphate anion is the same than concentration of K₃PO₄. 0,262 M

I hope it helps!

Two protons and two neutrons are released as a result of this reaction. Rn Po + ?Which particle is released?one alpha particletw

lys-0071 [83]

The nuclear reaction occurring is known as alpha-decay, and during this process, an alpha particle is released from a heavy radioactive nucleus to form a lighter more stable nucleus. The alpha particle is equivalent to a helium nucleus, which means it contains 2 protons and two neutrons (net charge of +2)
The decay equation is:
Rn → Po + α

The net ionic equation for the reaction between aqueous solutions of hf and koh is ________.

choli [55]

Answer:

The net ionic equation for the reaction between aqueous solutions of hf and koh is H⁺ + OH⁻ → H₂O (l)

Explanation:

This is the complete reaction:

HF (aq)+ KOH (aq) → KF (aq) + H₂O (l)

Hydrofluoric acid dissociates according to this equation:

HF → H⁺ + F⁻

And we get protons plus fluorides.

Sodium hydroxide dissociates into:

KOH → K⁺ + OH⁻

potassium cation and hydroxyls.

First of all, the aqueous compounds must be separated into their ions.

Aqueous are the only one, you can break apart.

Don't forget to establish solubility in the compounds. For this case no one is soluble in water.

We make the complete ionic equation with all the aqueous compounds:

H⁺ + F⁻ + K⁺ + OH⁻ → F⁻ + K⁺

and afterwards, cancel the ions that are repeat on reactant and product sides. This are the spectator ions.

As we eliminate F⁻ + K, the net ionic equation will be:

H⁺ + OH⁻ → H₂O (l)

A substance floats or sinks in another because of its relative

mart [117]

A substance floats or sinks in another because of its relative density. Take ice floating in water for example. Water is more dense than ice so ice floats.

Mass is incorrect as the buoyancy or ability of an object to float depends on the mass per volume, which is equivalent to density.
