Stels [109]

4FeS₂ + 11O₂ = 2Fe₂O₃ + 8SO₂↑


n(FeS₂) = m(FeS₂)/M(FeS₂) = 6000/120 = 50 моль

по уравнению реакции - n(O₂) = (11*n(FeS₂))/4 = (11*50)/4 = 137,5 моль

V(O₂) = n(O₂)*Vm = 137,5*22,4 = 3080 л


ответ: V(O₂) = 3080 л

Explain two research findings that support the claim that biological factors are influential in shaping personality.
Leno4ka [110]

Answer:

Two findings that claim that biological factors are influential in the formation of personality are:

  • Identical twins have more similar personalities than non-identical twins.
  • Separate identical twins raised in different environments have a more similar personality than non-identical twins raised together in the same environment.

Explanation:

Many debates have been raised about which factors influence the formation of our personality. Many scientists believe that personality is influenced entirely by environmental factors, which provide situations and experiences that build that personality.

However, some scientists through various studies and experiments have found that biological factors can have a strong influence on personality construction. This is because the results of these studies and experiments showed that identical twins (who are extremely similar biologically) have more similar personalities than non-identical twins. In addition, identical twins who were separated and raised in different environments still have more similar personalities than non-identical twins raised together in the same environment.
