Answer:
It Would be radioactive decay of the impurity, uranium, to become lead
Explanation:
The total number of atoms make up the products :
D) 1 carbon, 4 hydrogen, and 4 oxygen
<h3>Further explanation
</h3>
Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.
If O₂ is insufficient there will be incomplete combustion produced by CO and H and O
Hydrocarbon combustion reactions (especially alkanes)
For combustion of methane (CH₄) and two molecules of oxygen (O₂).

The number of atoms make up the products
CO₂ : 1 carbon, 2 oxygen
2H₂O : 4 hydrogen , 2 oxygen
The emission spectrum of a chemical element
Answer:
<h2>The answer is 2.5 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 of object = 10.02 g
density = 4.08 g/mL
The volume of the object is

We have the final answer as
<h3>2.5 mL to one decimal place</h3>
Hope this helps you
