A scientist adds heat to each of the following substances. Which will probably absorb the most heat before its temperature changes significantly?
50 g of liquid water
A scientist discovers a new substance. The molecules of the substance form hydrogen bonds with each other. When the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. Based on this information, what can the scientist infer about the substance?
It expands when it freezes.╖
Which of these best explains why a paper clip can float on water?
Water molecules near the surface produce more buoyant force than water molecules within the liquid.
Which of these best explains why the hydrogen atoms in a water molecule are attracted to Cl− ions in sodium chloride (NaCl)?
The hydrogen atoms have partial positive charges.
Answer:
Each molecule of O2 is made up of 2 oxygen atoms. So 1 mole of O2 molecules is made up of 2 moles of oxygen atoms. Therefore 1 mole of oxygen gas contains 2 moles of oxygen atoms. And 0.4 moles of oxygen gas contains 0.8 moles of oxygen atoms.
Explanation:
oh shi sorry I wish I could help but I'm stupid
Answer:
4.5 moles
Explanation:
One mole is equal to 6.022 x 10^23 atoms
2.71 x 10^24 atoms * 1 mol/ 6.022 x 10^23 atoms = 4.5 moles
