The answer is (3) the same chemical properties. The two samples are under same condition so they have same density. The gram-formula mass is the property of the matter itself. So it will not change. The volume will change when mass changes.
Answer:
Explanation:
A hydrogen atom has an atomic number of 1.
So it's proton number will always be 1.
A neutral hydrogen atom does not have any charge.
So it has the same amount of electrons as protons, which turns out to be also 1.
A neutral hydrogen atom has an atomic mass of ≈
1.00794 amu ≈ 1 amu.
To find the amount of neutrons, we take the proton number and subtract it from the mass number.
1 − 1 = 0
So a neutral hydrogen atom has no neutrons.
In summary,
A hydrogen atom has
1 proton
1 electron
0 neutrons
I hope that helps!
Answer: The oxygen atom in a water molecule carries a negative electrical charge.
Explanation:
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.
Hydrogen bonding (H-bonding) is an intermolecular force having partial ionic-covalent character. H-bonding takes place between a hydrogen atom (attached with an electronegative atom e.g. O, N and F) and an electronegative atom (O,N and F).
In , 
, O is a highly electronegative atom attached to a H atom through a covalent bond. Therefore O atom gets partial negative charge and H atoms get partial positive charge.
Answer:
A. boiling point
Explanation:
I'm not good at explaining science but...
Heating- keyword
I would take out b and c because you don't need heat for those.
When it's liquid, it would boil, not melt.
Vapor is also a sign of boiling.
Answer: That is true my friend.
Explanation:
Maybe not all substances but it can dissolve more than any other liquid.
