As in relative abundance , one is take reference
So,
One is taken as 1:
Other is subtracted from it:
(1 - 0.6011)(atomic mass of Ga-71)
Equation can be written as:
<span>69.723 = (0.6011)(68.9256) + (1-0.6011)x </span>
<span>(1-0.6011) is the percentage abundance of Ga-71 expressed in percentage: </span>
<span>Solving for x </span>
<span>28.2918 = 0.3989 x </span>
<span>x= 70.9246.......</span>
Lung cancer does not effect the environment. Lung cancer is caused by uncontrolled cell growth of tissue in the lungs inside the body therefore not effecting the environment.

Aluminum chlorate = Al(ClO₃)₃
Barium sulfate = BaSO₄
Aluminum sulfate = Al₂(SO₄)₃
Barium chlorate = Ba(ClO₃)₂
Al(ClO₃)₃ + BaSO₄⇒ Al₂(SO₄)₃ + Ba(ClO₃)₂
2Al(ClO₃)₃ + 3BaSO₄⇒ Al₂(SO₄)₃ + 3Ba(ClO₃)₂
Answer:
The given molecules are SO2 and BrF5.
Explanation:
Consider the molecule SO2:
The central atom is S.
The number of domains on S in this molecule is three.
Domain geometry is trigonal planar.
But there is a lone pair on the central atom.
So, according to VSEPR theory,
the molecular geometry becomes bent or V-shape.
Hybridization on the central atom is
.
Consider the molecule BrF5:
The central atom is Br.
The number of domains on the central atom is six.
Domain geometry is octahedral.
But the central atom has a lone pair of electrons.
So, the molecular geometry becomes square pyramidal.
The hybridization of the central atom is 
.
The shapes of SO2 and BrF5 are shown below:
Answer:
Explanation:
All you need to know is the atomic mass of platinum, and Avogadro's number.
2.00g Pt divided by atomic mass gives you the moles of platinum, and multiplying by avogadro's number (6.022 x 10^23) gives you the number of atoms.
Atomic mass of platinum can be found on any periodic table.
Hope this helped.
