magnesium and oxygen are elements. They are not compounds
Sugar crystal compounds are mixtures, as they are made up of multiple elements bonded together in specific ratios. The sugar crystals are composed of carbon, hydrogen, and oxygen atoms arranged in a specific molecular structure.
elements and compounds
Yes look at air it has oxygen and nitrogen(elements) and carbon dioxide(compound)
Oxygen typically forms compounds with elements such as hydrogen, carbon, nitrogen, and metals like iron and magnesium. These elements can participate in chemical reactions with oxygen to form oxides or other compounds.
In addition to carbon dioxide and water, other elements involved in photosynthesis include oxygen and hydrogen. Compounds like chlorophyll and enzymes are also critical in the process. Additionally, mixtures such as sunlight and nutrients in the soil play important roles in supporting photosynthesis.
Gold, Silver, Oxygen, and Hydrogen are not compounds because they are all elements.Sources- Science book. ^_^P.S- This better have helped!
They are NOT, Mg (metal) and O2 (bi-atomic gas) are elements and not compounds,BUTMagnesium oxide ( Mg=O ) is an ionic compound
Magnesium commonly bonds with elements such as oxygen (O), sulfur (S), and carbon (C) to form compounds like magnesium oxide (MgO), magnesium sulfate (MgSO4), and magnesium carbonate (MgCO3).
salt or water
Aluminum, iron, copper, and oxygen are all examples of elements. Elements are pure substances that cannot be broken down into simpler substances by chemical means. They represent the basic building blocks of matter, while compounds and mixtures consist of two or more elements or compounds combined. Gases can be elements, but not all elements are gases; for instance, aluminum and iron are solids at room temperature.
Nitrogen and oxygen are nonmetals.Copper oxide and sodium chloride are compounds, not elements.
These elements are oxygen and magnesium.
