Answer:</h2><h2>The primary requirement for good melting point determination is that the sample be in a fine powder form. This makes the heat transfer into the sample more efficient and reproducible, and also enhances the overall reflectivity of the sample for easier automated detection of the melt</h2><h2 />
Answer:
a liter is larger, hope that helps :)
Because the intention is to boil the solution, the purpose of the solvent is to dissolve so it has a higher boiling point so ensure it stays in liquid form and doesn't evaporate into a gas
also, a pure solvent is made of 1 substance so it has 1 boiling point and the solution must evaporate/boil first
Answer:
11 atoms
Explanation:
The formula for lead(II) bicarbonate is: Pb(HCO3)2.
Atoms in Pb(HCO3)2:
Pb=1, H=1×2, C=1×2, O=3×2
1+1×2+1×2+3×2
=1+2+2+6
=11 atoms
