Hi
Only The physical properties of a compound are usually the same as those of the elements from witch it is formed
Please next time make sure you posted your question with all the materials. When you said which that's means there are choices.
I hope that's help and I hope my answer is one of the choices.
Answer:
D: They are formed when atoms of different elements combine.
Explanation:
Example; CO2 is a compound because there are two different elements, Carbon and oxygen and if there is 2 of oxygen and its a part of a compound it turns from being oxygen to dioxide. Hence, my explanation that D is the correct answer. Hope this helps, please give brainliest.
Answer: B: False
Explanation: In the past, scientists may not have prioritized environmental concerns. However, with the rise of global warming and other environmental risks, modern-day scientists are deeply invested in understanding and mitigating the human impact on the environment. They are actively searching for solutions to minimize or eliminate these threats to human safety.
Most oceanic gas hydrates are created when bacteria breaks down organic matter trapped in ocean-floor sediments
I hope that's help !

i knew this without looking at the answer
i hope i helped though
An increase in the amount of greenhouse gases in the atmosphere
A decrease in the amount of air pollution
A cooling effect on Earth’s climate
2. Evaporation occurs when a ____ changes into a ____. *
Solid; liquid
Gas; liquid
Liquid; gas
Solid; gas
3. What is the definition of anaerobic? *
Producing oxygen
Producing methane
Containing bacteria
Lacking oxygen
4. What is the purpose of regularly mixing a compost pile? *
To decrease the temperature in the compost pile
To reduce the amount of oxygen in the compost pile
To prevent the production of methane in the compost pile
All of the above
Answer:
An increase in the amount of greenhouse gases in the atmosphere
Liquid; gas
Lacking oxygen
To decrease the temperature in the compost pile
Explanation:
1. Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.
2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.
3. Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.
4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
Answer:
Many
Explanation:
Answer;
Key
A sorting device that is useful in classifying by observation is a key.
Explanation;
Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms.
They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
Therefore, keys can be used to identify a living organism or determine which group it belongs to by answering questions on the key about characteristics of living things.
