Iron-60 Express your answer as an isotope.
lys-0071 [83]

Isotopes are variants atoms of the same element, having same number of atomic(proton) number but different number of neutrons and mass number.

Considering iron-60

  • The atomic number which also equals the number of protons for the element iron as can be seen on the periodic table is 26
  • The name  iron-60 also tells us that this particlar  isotope's mass number is 60.  
  • The chemical symbol for Iron  is Fe

Now expressing  as an isotope iron-60 becomes   ⁶⁰₂₆Fe ( very unstable )

Other stable isotopes of Iron include   ⁵⁴₂₆Fe , ⁵⁶₂₆Fe, ⁵⁷₂₆Fe and ⁵⁸₂₆Fe

What mass of water is produced by the combustion 1.2 x 10^26 molecules of butane ?
podryga [215]

Answer:

17.934 kg of water

Explanation:

If balanced equation is not given; this format can come in handy.

For any alkane of the type : CₙH₂ₙ₊₂ , it's combustion reaction will follow:

2CₙH₂ₙ₊₂ + (3n+1) O₂  →  (2n)CO₂ + 2(n+1) H₂O

For butane:

2C₄H₁₀(g) + 13O₂(g) →  8CO₂(g) + 10H₂O(l)

2 moles of butane gives 10 moles of water.

1 mol of any substance has Avogadro number(N) of molecules in it( 6.022 x 10²³)

Mass of 1 mole of any substance is equal to it's molar mass

So, if 2 x N molecules of butane gives 10 x 18 g of water.

Then  1.2 x 10²⁶ molecules will give:

\frac{1.2 \times 10^{26} \times 180}{2 \times 6.022 \times  10^{23}}

= 17.934 x 10³ g of water

= 17.934 kg of water
