Answer:
mass and volume are independent. Two objects with the same volume can have different masses hence they can have different densities
Explanation:
The mass of atoms their size and how they are arranged determine the density
There are two that seem correct to me but i would go with the first answer choice, a mole of cu atoms has the same number or atoms as a mole of he atoms.
Two [hydrogen] atoms and one [oxygen] atom
Answer:
atoms bond to attain neutral configuration or to get noble gas configuration.
Explanation:
atoms always want to be stable by attaining noble gas configuration.
they do so by forming bonds. they also bond to each other to make their outer electrons stable that is if the atom has an excessive electron than its neutral configuration it can bond to another atom that has one less electron than its neutral configuration by ionic bond.
