Answer:
Double displacement reaction
Explanation:
The chemical reaction is as follows :
NaCl + Pb(NO3)2 → PbCl + NaNO3.
Balanced equation:
Pb(NO3)2 + 2NaCl → PbCl2 + 2NaNO3
The reaction is a double displacement reaction . A double displacement reaction is a chemical reaction between compound where the cations and the anions of the 2 reactants exchange places to form a new product.
Double displacement reaction, the 2 reactants exchange ions to form new compounds. Double displacement reaction usually produce a solid precipitate. A good illustration of a double displacement reaction is
AB + CD → AD + CB.
From the reaction above the Sodium ion replace lead to from sodium nitrate while lead replace sodium to form the precipitate lead chloride. The anions(negatively charged ions) also exchange position.
Explanation:
Mass of one atom of water = Mass of 1 mole / Avogadro's number
Mass of one atom of water = 18g/mol / 6.022×10²³molecules
Mass of one atom of water = 2.989 × 10^-23 g
Mass of glucose = 180(one molecule)
Mass of 100 molecules of glucose = 180×100 =18000
It's wood i believe. (dont mind this i had to make it longer)
