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
Cardiovascular and respiratory is probably the correct answer
Everything dead would just keep piling up and up and up and nothing would ever go away! The Earth would be like a giant landfill! <span />
Answer:
C. C
Explanation:
Intermediates are species that are neither reactants nor products.
In this reaction;
Reactant = C3H8 and O2
Products = CO2 + H2O
From the options, the only element that is either the reactants nor products is;
C. C
