Answer:
1g of bromobenzene = 3.84× 10^21 molecules
Explanation:
Molar mass of bromobenzene (C6H5Br)= 79.9+(12×6)+ 5= 156.9
156.9g(1mole) has 6.023×10^23 molecules
This implies that 1g will contain 6.023×10^23/156.9 = 3.84×10^21 molecules
Answer:
Radiometric dating, is called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Answer:
A) MgCO₃ is insoluble
Explanation:
Based on the rules of solubility:
All nitrates are soluble. That means Pb(NO₃)₂ is soluble.
All ammonium ions are soluble. NH₄Br is soluble.
All phosphate are insoluble except when combined with group I ions (Li, Na, K...) K₃PO₄ is soluble.
Also, all carbonates are insoluble except when combined with group I ions. That means Li₂CO₃ is soluble and:
<h3>A) MgCO₃ is insoluble</h3>
