Answer:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons. Chemical bonds are formed when the outermost electron shells are not completely filled and atom needs more (or less) electrons to completely fill the outermost shell.
Explanation:
Answer:
A
Explanation:
It's A since a theory is a widely accepted explanation of something in the natural world which can be tested but not 100% proven.
286.8g of carbon dioxide forms when 95.6g of propane burns. The total atomic mass of the propane is 44(g). The total mass of the carbon dioxide formed when 44g of propane is burnt is 132(g). 44 divided by 44 equals 1. 132 divided by 44 equals 3. Therefore the amount of propane to carbon dioxide is in a 1:3 ratio. Therefore, 95.6 multiplied by 3 gives you the amount of carbon dioxide formed.
35.0 g would be the mass according to law of mass conservation in an isolated system in this case closed jar
