First, convert 2.0 mL of AlCl3 to grams using the density, which is 2.48g/mL. So 2.48g/mL * 2.0 mL = 4.96g. Then find the molar mass of aluminum chloride and divide 4.96 by this number, which is 133.34g. 4.96g*(1mol/133.34g) = .0372 mols AlCl3. Check for significant digits though.
Heptane has nine structural isomers are 2-methylhexane, 3-methylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane and 2,2,3-trimethylbutane. Each compound must have the same molecular formula but the structure of each are different from each other.
A nuclear reaction changes the number of protons and or neutrons in an atom.
<h3>What do nuclear reactions change in the atom?</h3>
A nuclear reaction is a type of reaction that results in the change of the nucleus of an atom. We know that a nucleus of an atom is made up of protons and neutrons.
So we can conclude that a nuclear reaction changes the number of protons and or neutrons in an atom.

False is the correct answer.
Answer:
Its unreactive since its outer shell is filled up and also does not form a covalent bonding.
