2-butane is the correct answer
Answer:
All exothermic reactions _c.release energy____
Explanation:
Exothermic reactions are those that give off energy, for example in the form of heat in combustion (it has a negative enthalpy variation, the energy of the products being less than the energy of the reagents)
Answer:
Assuming the product is AlCl3
Assuming its 1008 g of metalic Al
It will yeld 4234 g of aluminium chloride.
Explanation:
Al molar mass is 26.98 g/mol, so in 1008 g of Al there is 37.36 mols of Al
The stoichometry ratio between Al and AlCl3 is 1:1, so 37.36 mols of Al would form 37.36 mols of AlCl3 if the reaction were complete, but only 85% yelds, so 1008 g of Al makes up to 0.85x37.36 mols of AlCl3 (31.76 moles)
AlCl3 molar mas is 133.33 g/mol, so 31.76 moles has 4234 g
Answer: Hydrogen bonds
Explanation: Hydrogen bonds allow two molecules to link together temporarily. Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.
