Since SeO2 dissolves in water to produce selenium acid, it is regarded as an acidic oxide.

The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. 350 °C (662 °F; 623 K). The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. It serves as a catalyst, reagent, oxidizing agent, and antioxidant in lubricating oils. OSHA regulates selenium oxide; thus, it is listed on the Hazardous Substances List. It can be produced chemically by dehydrating selenous acid or chemically by burning selenium in oxygen, nitrogen dioxide, or hydrogen peroxide.

Aqueous potassium phosphate was mixed with aqueous magnesium chloride, and a crystallized magnesium phosphate product was formed

scoray [572]

<u>Answer:</u> The other product formed is potassium chloride.

<u>Explanation:</u>

Precipitation reaction is defined as the chemical reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.

The chemical equation for the reaction of potassium phosphate and magnesium chloride follows:

$2K_3PO_4(aq.)+3MgCl_2(aq.)\rightarrow Mg_3(PO_4)_2(s)+6KCl(aq.)$

By Stoichiometry of the reaction:

2 moles of aqueous solution of potassium phosphate reacts with 3 moles of aqueous solution of magnesium chloride to produce 1 mole of solid magnesium phosphate and 6 moles of aqueous solution of potassium chloride.

Hence, the other product formed is potassium chloride.

If 2.0 mL of 6.0M HCl is used to make a 500.0-mL aqueous solution, what is the molarity?

RideAnS [48]

Answer:

0.024M

Explanation:

Data obtained from the question include:

C1 = 6M

V1 = 2mL

C2 =?

V2 = 500mL

The molarity of the diluted solution can be obtained as follows:

C1V1 = C2V2

6 x 2 = C2 x 500

Divide both side by 500

C2 = (6 x 2) /500

C2 = 0.024M

The molarity of the diluted solution is 0.024M
