What does selenium and oxygen combined together make?
Selenium dioxide, SeO2
Formula for ionic elements aluminum and selenium?
The ionic formula for aluminum is Al3+ and for selenium is Se2-. When these two ions combine, the formula for the resulting ionic compound is Al2Se3.
Is selenium combustible?
Selenium is not combustible on its own, as it is a nonmetallic element. However, selenium compounds can be combustible and may release toxic fumes when burned. It is important to handle selenium and its compounds with care to avoid potential fire hazards.
What does locoweed have to do with selenium?
Locoweed is a plant that can accumulate high levels of selenium from the soil. When livestock like cattle graze on locoweed, they can ingest toxic amounts of selenium, which can lead to selenium poisoning and various health issues.
A 7.300 gram sample of aluminum was quantitatively combined with a sample of selenium to form a compound The compound weighed 39.35 grams What is the empirical formula for this compound?
The molar mass of aluminum is 26.98 g/mol, and the molar mass of selenium is 78.96 g/mol. Using the given masses, we find that there are 0.270 moles of aluminum and 0.499 moles of selenium in the compound. Dividing by the smallest number of moles (0.270) gives us the empirical formula Al2Se3.
How do toxic is selenium?
Elemental selenium is nontoxic, hydrogen selenide and other selenium compounds are extremely toxic and resemble arsenic in their physiological reactions.

Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
Is burning aluminum toxic?
Yes, burning aluminum can release toxic fumes that can be harmful if inhaled.

Is aluminum foil toxic when burned?
Yes, burning aluminum foil can release toxic fumes that can be harmful if inhaled. It is not recommended to burn aluminum foil.
Is al2se3 ionic or molecular compounds?
Al2Se3 is an ionic compound. It is composed of aluminum cations (Al3+) and selenium anions (Se2-), which are held together by ionic bonds due to the transfer of electrons from aluminum to selenium.
What is selenium combined with calcium?
Selenium combined with calcium is a mineral supplement that provides both selenium and calcium in a single dosage. Selenium is an essential mineral with antioxidant properties, while calcium is vital for bone health and muscle function. This combination may help support overall health, especially for individuals who have deficiencies in either mineral.
Is melting aluminum cans toxic?
Melting aluminum cans is not toxic, as aluminum is a non-toxic metal. However, it is important to melt aluminum cans in a well-ventilated area to avoid inhaling any fumes that may be released during the melting process.
