Answer:
d= 50.23 g/cm³
Explanation:
Given data:
radius = 137.9 pm
mass is = 5.5 × 10−22 g
density = ?
Solution:
volume of sphere= 4/3π r³
First of all we calculate the volume:
v= 4/3π r3
v= 1.33× 3.14× (137.9)³
v= 1.33 × 3.14 × 2622362.939 pm³
v= 1.095 × 10∧7 pm³
v= 1.095 × 10∧-23 cm³
Formula:
Density:
d=m/v
d= 5.5 × 10−22 g/ 1.095 × 10∧-23 cm³
d= 5.023 × 10∧+1 g/cm³
d= 50.23 g/cm³
Answer:
e. BaSO4 and KCI.
Explanation:
Hello there!
In this case, given the reactants side:
It is possible to realize that after the reaction takes place barium replaces potassium and therefore barium sulfate and potassium chloride are formed:
Therefore, the products turn out to be e. BaSO4 and KCI.
Best regards!
