Which of the following statements is one of the postulates in Dalton's atomic theory? -All compounds are composed of multiple elements combined together.

-Atoms of one element cannot be changed into another element through a chemical reaction.

-Atoms of different elements can physically mix together.

-Atoms of one element can be changed into atoms of another element through a chemical reaction.

1. they vary with a higher number because boiling is way hotter than melting

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
