If you dissolve 0.0147 kg of glucose (c6h12o6) using 0.150 l of water with a density of 1.00 g/ml, what will be the molality?

Bonds between metals and nonmetals tend to be ionic, but bonds between nonmetal atoms tend to be covalent. Explain why this is true, using your understanding of electronegativity and ionization energy for these groups of elements.

What type of orbital do the lone pair electrons on oxygen occupy in ethanol?

What type of reaction is 2A1Br3 + 3K2SO4+6KBr + Al2 (SO4) 3 Synthesis/Combination Decomposition Single Replacement Double Displacement or Combustion?

Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses.
