Answer: Y → Z → X
Explanation:
The three states of matter shown in the picture are:
X) solid - in solids, molecules are bond together, so they are not free to move. They can only vibrate about their position - therefore they have the least freedom of motion
Z) liquid - in liquids, molecules are not bond, so they can move past each other. However, there are still strong intermolecular forces that keep the molecules close to each other, so they are not completely free to move - so this is the intermediate amount of motion
Y) Gas - in gases, molecules are completely free to move, since the intermolecular forces between them are negligible. Therefore, this is the state where molecules have the greatest amount of motion
False, compounds can be formed from chemical reactions, mixtures can not
Answer:
neither they both have the same molecule #
Explanation:
Answer:
Tetrahedral
Bent
Explanation:
A molecule in sp3 hybridization is ordinarily expected to exhibit tetrahedral electron domain geometry. This implies that it has four electron domains.
We were specifically informed in the question that two lone pairs are present. Remember that lone pairs distort the molecular geometry away from the expected geometry based on VSEPR theory.
Therefore, the bond angle of the molecule is <<109.5 degrees and its molecular geometry is bent (e.g water)
Answer:
two
Explanation:
wo moles of chlorine gas reacts with one mole of sodium to produce two moles of sodium chloride.
