Answer to Question #111995 in Physical Chemistry for madisyn

Question

identify the labeled parts in the figure.



i. Which of the labeled parts is a chemical symbol?
ii. Which of the labeled parts is a coefficient?
iii. Which of the labeled parts is the number of atoms of the element?
iv. Which of the labeled parts indicates that only one atom of the element is present in the substance?

Answer 1

$CaCl_2 + 2AgNO_3 → Ca(NO_3)_2 + 2AgCl↓$

so let's suppose this is our chemical equation then here stociometric coefficient is

For CaCl₂ it is 1

for AgNO₃ it is 2

for Ca(NO₃)₂ it is 1

for AgCl it is 2

from the stochiometric coefficient we mean that if 1 moles of calcium chloride reacts with 2 moles of silver nitrate we will get 1 moles of calcium nitrate and 2 moles of silver chloride
