Iron-60 Express your answer as an isotope.

Chemistry
1 answer:
lys-0071 [83]3 years ago
4 0

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

Answer:

0.131 mol

Explanation:

To convert grams to moles, you need to use the molar mass.  The molar mass is the mass number.  You can find this on the periodic table.  The molar mass of sodium is 22.990 g/mol.

(3.02 g)/(22.990 g/mol) = 0.131 mol

Why bromine is a ring deactivator as it is ortho-Para directing group??
Anettt [7]

Answer:

here you go

Explanation:

Halogens are very electronegative. This means that inductively they are electron withdrawing. However, because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Electron withdrawing groups are meta directors and they are deactivators.

<span><span>NaOH + HCl --> NaCl + H2Oso here 1 mole of NaOH reacts with 1 mole of HCl. Hence it is required to convert the amount of HCl and NaOH in to moles.Number of HCl moles Concentration of the solution = 2.00M = 2 mol/ literVolume of the solution           = 22.4 mlNumber of HCl moles              = (2mol/1000 ml)*22.4 ml                                            =  0.0448 mol</span></span>
