Question

Be-Beo-Be(NO3)2-Be(OH)2 / K2BeO2

Answer 1

2Be+O2=2BeO

BeO+2HNO3=Be(NO3)2+H2O

Be(NO3)2+2KOH=Be(OH)2+2KNO3

Be(OH)2+2KOH=K2BeO2+2H2O

K2BeO2+H2SO4=BeSO4+2KOH

Answer 2

The chemical formula you provided, Be-Beo-Be(NO3)2-Be(OH)2 / K2BeO2, appears to be a combination of different beryllium compounds. However, the formula is not properly balanced and seems to be missing some crucial information.

Let's break down the components you mentioned:

1. Be: This represents the element beryllium, which has the atomic number 4.

2. Be(NO3)2: This is the formula for beryllium nitrate, which consists of beryllium (Be) and nitrate (NO3-) ions. The formula indicates that two nitrate ions are combined with one beryllium ion. To balance the charge, the formula would be Be(NO3)2.

3. Be(OH)2: This is the formula for beryllium hydroxide, which consists of beryllium (Be) and hydroxide (OH-) ions. Similar to beryllium nitrate, the formula indicates that two hydroxide ions are combined with one beryllium ion. The balanced formula would be Be(OH)2.

4. K2BeO2: This is the formula for potassium beryllium oxide. It consists of two potassium (K+) ions and one beryllium oxide ion (BeO2-). The balanced formula would be K2BeO2.

To summarize, the correct representation of the compounds you mentioned would be:

Beryllium nitrate: Be(NO3)2 Beryllium hydroxide: Be(OH)2 Potassium beryllium oxide: K2BeO2
