antiseptic1488 [7]

Mass of Aluminum (in g) : 4.104

<h3>Further explanation</h3>

Reaction

2 Al(s) + 6 HCl(aq) → 2 AICI₃ (aq) + 3 H₂(g)

mol HCl :

\tt 1.3\times 0.35=0.455

mol Al :

\tt \dfrac{2}{6}\times 0.455=0.152

mass of Aluminum :

\tt 0.152\times 27~g/mol=4.104~g

According to vsepr theory, the bond angle in h2se would be predicted to be:
ella [17]
The bond angle in H2Se would be predicted should be less than 109.5 degrees. Particle shapes can be anticipated in light of Lewis dab structure utilizing the VSEPR hypothesis. VSEPR remains for Valence Shell Electron Pair Repulsion. It expresses that electron matches in the valence shell of a particle repulse each other; their sub-atomic geometry is the consequence of this shock.

A 0.600 g sample of a compound of arsenic and oxygen was found to
ss7ja [257]

Answer:

The answer is <u>C. As2O3</u>

Explanation:

0.600 gr of Arsenic and Oxygen.

0.454 gr of Arsenic

So, 0.146 gr of Oxygen will be in the compound.

- First: The grams of each element must be divided by its atomic weight:

  • 0.454 gr As / 74.92u As = 0.00606
  • 0.146 gr O / 16u O = 0.009125

- Both results must be divided by the lowest number found:

  • 0.00606 / 0.00606 = 1 As
  • 0.009125 / 0.00606 = 1.5 O

- As one of the values ​​is not an integer then both results are multiplied until both give an integer:

  • 1 As * 2 = 2 As
  • 1.5 O * 2 = 3 O

- Then the answer is given:

  • <u>As2O3</u>
