A formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.
Answer:
Lead
Explanation:
Lower the specific heat faster it will heat, meaning liquid will heat up slowly than any other material mentioned above. Thus lead will heat up faster
Answer:
The empirical formula of the compound is = 
The name of the compound is potassium bromate.
Explanation:
Mass of potassium = 4.628 g
Moles of potassium = 
Mass of bromine = 9.457 g
Moles of bromine = 
Mass of oxygen = 5.681 g
Moles of oxygen = 
For empirical formula of the compound, divide the least number of moles from all the moles of elements present in the compound:
Potassium :
Bromine;
Oxygen ;
The empirical formula of the compound is =
The name of the compound is potassium bromate.
Answer:
Complex formation
Explanation:
At first sight, one may think that a reaction between calcium oxalate and platinum metal is impossible considering the relative positions of the two metals in the electrochemical series.
However, in solution, calcium oxalate dissociates into calcium and oxalate ions. When platinum is added to this solution, a complex is formed between the platinum ions and the oxalate ions. Hence a reaction occurs for this reason.
Sufficient energy upon collision of particles and correct orientation of particles
