Answer: 305 g of Be_3(PO_4)_2 will be produced from 38 grams  of beryllium oxide

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} BeO=\frac{38g}{25g/mol}=1.52moles

3BeO+2FePO_4\rightarrow Be_3(PO_4)_2+Fe_2O_3

According to stoichiometry :

3 moles of BeO produce = 1 mole of Be_3(PO_4)_2

Thus 1.52 moles of BeO will produce =\frac{1}{3}\times 1.52=0.507moles  of Be_3(PO_4)_2

Mass of Be_3(PO_4)_2=moles\times {\text {Molar mass}}=0.507moles\times 602g/mol=305g

Thus 305 g of Be_3(PO_4)_2 will be produced from 38 grams  of beryllium oxide

The tendency of an element to react is closely related to
sweet-ann [11.9K]

<u>Answer:</u> The tendency of an element to react is closely related to the number of valence electrons in the element.

<u>Explanation:</u>

Chemical reactivity is defined as the tendency of an element to loose of gain electrons.

Metals tend to loose electrons and so their chemical reactivity is the tendency to loose electrons.

Non-metals tend to gain electrons and so their chemical reactivity is the tendency to gain electrons.

The number of electrons that an element will loose or gain depends on the number of valence electrons present around that element.

<u>For Example:</u> Chlorine has 7 valence electrons and need 1 electron to complete its octet, whereas sulfur has 6 valence electrons and need 2 electrons to complete its octet.

So, chlorine will gain 1 electron easily than sulfur and thus, is more reactive than sulfur.

Hence, the tendency of an element to react is closely related to the number of valence electrons in the element.

A student obtains a beaker containing a solution that is determined to have a hydrogen ion
OleMash [197]

Answer:

pH = 13.1

Basic

Explanation:

Step 1: Given data

Hydrogen ion concentration ([H⁺]): 6.7 × 10⁻¹⁴ M

Step 2: Calculate the pH of the solution

We will use the definition of pH.

pH = -log [H⁺]

pH = -log 6.7 × 10⁻¹⁴ = 13.1

  • When pH < 7, the solution is acid.
  • When pH = 7, the solution is neutral.
  • When pH > 7, the solution is basic.

Since pH > 7, the solution is basic.
