Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance.
Answer:
8.0 mol O₂
Explanation:
Let's consider the complete combustion reaction of C₉H₁₂.
C₉H₁₂ + 12 O₂ → 9 CO₂ + 6 H₂O
The molar ratio of C₉H₁₂ to O₂ is 1:12. The moles of O₂ required to react with 0.67 moles of C₉H₁₂ are:
0.67 mol C₉H₁₂ × (12 mol O₂/1 mol C₉H₁₂) = 8.0 mol O₂
8.0 moles of O₂ are required to completely react with 0.67 moles of C₉H₁₂.
The atoms of different chemical elements can be differentiated based on the number of protons.
Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).
The atomic number represented the number of protons in the nucleus of an element. For example:
- The element that has only 1 proton in his nucleus is Hydrogen atom.
- The element that has 2 protons in his nucleus is Helium atom.
<h3>What is an atom?</h3>
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

Answer:
The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure.
The second structure has more hydrogens attached to the β carbons than the first structure.
Explanation:
It is possible to explain the reaction based on Zaitsev’s rule that states that an elimination will normally lead to the most stable alkene as the major product. This normally translates to it giving the most substituted alkene.
The two adjacent carbons in the first molecule are secondary. That means the two products will produce a disubstituted alkene but in the second molecule just one product will be disubstituted. Thus:
The first structure has more hydrogens attached to the β carbons than the second structure. <em>FALSE</em>. If the structure has more hydrogens will produce an alkene less stable.
The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure. <em>TRUE</em>. As the first structure have more alkyl groups the product is most stable.
The major and minor products formed from the second structure have more alkyl groups on the C═C than those formed from the first structure. <em>FALSE</em>. Is the opposite of the last option.
The second structure has more hydrogens attached to the β carbons than the first structure. <em>TRUE</em>. As the second structure has more hydrogens, the alkenes produced will be less substituted being less stable.
