Answer:
E) NaF and SrO
Explanation:
The ionic bonding occurs between atoms with a great difference in electronegativity. This usually happens between a metal and a non-metal.
<em>In which pair do both compounds exhibit predominantly ionic bonding? </em>
A) KCl and CO₂. NO. C and O are non-metals and present covalent bonding.
B) SO₂ and BaF₂. NO. S and O are non-metals and present covalent bonding.
C) F₂ and N₂O. NO. Both compounds contain non-metals and present covalent bonding.
D) N₂O₃ and Rb₂O. NO. N and O are non-metals and present covalent bonding.
E) NaF and SrO. YES. Na and Sr are metals while F and O are non-metals.
What is the check all that apply?
Answer:
Stanley Miller and Harold Urey
Explanation:
Experiments in which electricity was discharged into a vessel containing hydrogen gas, water vapor, methane, and ammonia were conducted by Miller and Urey.
Biochemists Stanley Miller and Harold Urey conducted an experiment in the 1950s which revealed many organic compounds can be spontaneously formed by simulating the early atmosphere conditions of Earth.
Mmm this sounds like ceviche to me! It's a Latin American dish with seafood marinated in lemon/lime, cilantro, peppers, and other good stuff!
