Hi there! :)
Both are compounds.
contains 1 carbon (C) atom and 2 oxygen (O) atoms.
It contains two different elements, so it is a COMPOUND.
is an IONIC compound with elements Sodium (Na) and Oxygen (O), which are different elements. Therefore, it is also a COMPOUND.
Answer:
I say the correct answers are primary and secondary and teriary.
Explanation:
I say you are right!!
A mixture of charcoal, sand, sugar, and water is a heterogeneous mixture. Sugar can easily dissolve in water. Slightly heating the mixture will ensure all of the sugar is dissolved in the water. The mixture then can be filtered to separate out sugar solution from sand and charcoal. The mixture of sand and charcoal is washed several times with water and filtered so that no traces of sugar solution remain in the mixture. To the mixture containing sand and charcoal, water is added. Charcoal being lighter floats on the surface of water, whereas sand being heavy sinks to the bottom. The charcoal floating can be removed manually. After all the charcoal is removed, the mixture of sand and water is again filtered and the sand collected on filter paper is dried. Therefore, by using the above process sand can be separated out from a mixture of charcoal, sand, sugar, and water.
Photosynthesis is the ability for a plant to turn light into energy, thus feeding it
Global warming will cause see levels to rise since a lot of water is stored in ice sheets which will melt. All of the melt water will end up in the ocean causing sea levels to rise.
I hope this helps. Let me know if anything is unclear.
