Question

question 19 (1 point)
write the chemical formula for each covalent compound?
tetraphosphorus decoxide

question 20 (1 point)
write the chemical formula for each covalent compound?
xenon tetrafluoride

Explanation:

Step1: Analyze prefixes for Tetraphosphorus decoxide

• "Tetra -" means 4, so there are 4 phosphorus (\(P\)) atoms.
• "Deca -" means 10, so there are 10 oxygen (\(O\)) atoms.
• The chemical formula is \(P_4O_{10}\).

Step2: Analyze prefixes for Xenon tetrafluoride

• "Tetra -" means 4.
• Xenon is \(Xe\) and fluorine is \(F\).
• The chemical formula is \(XeF_4\).

Answer:

Tetraphosphorus decoxide: \(P_4O_{10}\)
Xenon tetrafluoride: \(XeF_4\)
