Answer:
The answer is
<h2>40.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 420 g
density = 10.5 g/cm³
The volume is

We have the final answer as
<h3>40.0 mL</h3>
Hope this helps you
Answer:
4
Explanation:
Since there are 3 carbons on the left side, make the coefficient of CO2 equal to 3.
Also, since there are 8 hydrogen on the left side, make the coefficient of H2O equal to 4.
This means there are 3(2)+4=10 oxygen atoms on the right, making the coefficient of O2 equal to 5.
Answer:
The resonance forms of O3 are attached as an image.
Explanation:
A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.
The given compound is ozone, having the chemical formula
O3 = 6 electrons * 3 = 18 electrons
O → prefers to have a complete their octet
The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.
Answer:
1 g of Carbon
Explanation:
This is because because carbon has lower molar mass than thorium or copper so a 1-g sample of carbon contains more atoms than 1 g of cobalt or lead.
