We only can make ozone layer by adding 3 oxygen atoms or we cannot
If there is a question here I don't see it.
If 1.30g of steam at 100.0 ∘C condenses into 40.0g of water, initially at 31.0∘C, in an insulated container, what is the final temperature of the entire water sample? Assume no loss of heat into the surroundings.
Remember you get faster service if you don't post piggy back. Go to the top of the page and post your own question all by itself.
heat lost by steam + heat lost by 1.3g liquid H2O + heat gained by 31 degree H2O = 0
[mass steam x -heat vap] + [mass steam to H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Substitute and solve for T final. I get something like 49 C or so if I didn't goof. Post your work if you get stuck.
The ozone layer is a layer of ozone (O3) molecules in the Earth's atmosphere. Ozone is formed when three oxygen atoms (O) combine together. So, in order to create the ozone layer, we need to add three oxygen atoms to form each ozone molecule.
However, we cannot directly create the ozone layer ourselves. The ozone layer is naturally formed in the Earth's stratosphere through a process called the ozone-oxygen cycle. This cycle involves the interaction of oxygen molecules (O2) and various forms of ultraviolet (UV) radiation from the Sun.
Here is a step-by-step explanation of the ozone-oxygen cycle:
1. Oxygen molecules (O2) in the stratosphere are split apart by high-energy UV-C radiation from the Sun. This process is known as photodissociation.
2. The split oxygen molecules (O) then react with other oxygen molecules (O2) to form ozone (O3). This reaction is facilitated by UV-B radiation. The process can be written as:
O2 + UV-B radiation 🡪 2O
O + O2 🡪 O3
3. Ozone molecules (O3) absorb UV-C and UV-B radiation, shielding the Earth's surface from the harmful effects of these radiations.
4. Through another series of reactions, ozone molecules are broken down into oxygen molecules and single oxygen atoms. This process is also driven by UV-B and UV-C radiation:
O3 + UV-B radiation 🡪 O2 + O
O3 + UV-C radiation 🡪 O2 + O2
5. The freed oxygen atoms (O) then combine with other ozone molecules (O3) to reform oxygen molecules (O2):
O + O3 🡪 2O2
These reactions continuously occur in the stratosphere, creating and depleting ozone in a delicate balance. The net effect of this cycle is the creation and maintenance of the ozone layer.
So, while we cannot directly create the ozone layer ourselves, we can take actions to protect and preserve it by reducing the release of ozone-depleting substances into the atmosphere, such as chlorofluorocarbons (CFCs) commonly found in aerosol sprays and refrigerants.
