The correct answer is b, 18 protons
When earth first formed it was likely composed of hydrogen, helium and other gases that contained hydrogen but it didnt last for very long because the solar wind from the sun blew it away solar wind is stream of charged particles such as electrons, protons, and aloha particles. We now have a magnatic field surrounding earth that sheilds us from the solar wind
Answer:
C₃H₆O₃
Explanation:
Data:
EF = CH₂O
MM = 90. g/mol
Calculations:
EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u
The molecular formula is an integral multiple of the empirical formula.
MF = (EF)ₙ
MF = (CH₂O)₃ = C₃H₆O₃
probably radiation. the sun's radiation waves are heating up the windows that are also heating up the house. but idek anymore sorry sister
