last one? don't take my word though
Explanation:
the suns heat is related to nuclear fusion
A Campfire is an example, the solid wood becomes ash.
Answer:
It is buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
Explanation:
Hello!
The Chemical reaction is the following:
2F₂(g) + 2 H₂O(g) → O₂(g) + 4HF(g)
If we assume that all the gases are ideal gases,
we can describe the coefficients of this reaction as Volume rather than moles, so we can apply the following equations:
![2 L F_2* \frac{2 L H_2O}{2 L F_2}=2 L H_2O \\ \\ 2 L F_2* \frac{1 mol O_2}{2 L F_2}=1 mol O_2 \\ \\ 2 L F_2* \frac{4 mol HF}{2 mol F_2}= 4 mol HF](https://tex.z-dn.net/?f=2%20L%20F_2%2A%20%5Cfrac%7B2%20L%20H_2O%7D%7B2%20L%20F_2%7D%3D2%20L%20H_2O%20%5C%5C%20%5C%5C%202%20L%20F_2%2A%20%5Cfrac%7B1%20mol%20O_2%7D%7B2%20L%20F_2%7D%3D1%20mol%20O_2%20%5C%5C%20%5C%5C%202%20L%20F_2%2A%20%5Cfrac%7B4%20mol%20HF%7D%7B2%20mol%20F_2%7D%3D%204%20mol%20HF%20)
So,
2 L of Water Vapor reacts with the fluorine; and
1 L of Oxygen and
4 L of Hydrogen Fluoride are produced.
Have a nice day!
Answer:
The answer to your question is U-234
Explanation:
Data
Thorium-234
beta emission twice
Definition
Beta emission is when a beta particle (electron) is emitted from an atomic nucleus.
First beta emission
²³⁴₉₀Th ⇒ ²³⁴₉₁Pa + e⁻
Second beta emission
²³⁴₉₁ Pa ⇒ ²³⁴₉₂U + e⁻
The atom will be Uranium-324
