Hyponym is the another name for hard water.
Explanation:
Please Mark me brainliest
Protons and neutrons are held together rather closely in the center of the atom. Together they make up the nucleus, which accounts for nearly all of the mass of the atom.
<span>Electrons move rapidly around the nucleus and constitute almost the entire volume of the atom. Although quantum mechanics are necessary to explain the motion of an electron about the nucleus, we can say that the distribution of electrons about an atom is such that the atom has a spherical shape.</span>
Lewis Structure of
Oxygen Difluoride is sketched as....
Step 1: Calculate the
total number of valence electrons present in OF₂. This is done by adding all valence electrons of each element. i.e...
Valence e⁻s of Oxygen = 6
Valence e⁻s of Fluorine-1 = 7
Valence e⁻s of Fluorine-2 = 7
------------
Total Valence e⁻s
20Step 2: Draw central element (O) in center surrounded by fluorine atoms. Now, sketch a single bonds between O and both F atoms. Now, subtract 2 electrons per single bond from total valence electrons.. i.e..
Total Valence e⁻s = 20
2 single bonds (2 × 2) = 4
-----------
16Now, distribute remaining 16 electrons on each element to complete its
octet starting from most electronegative element.
Lewis structure of OF₂ is as follow,
well if you round to the nearest cent the number 0.332 move the decimal down 2 time so it would be 33 it the the answer would be "a"
im sorry if im wrong im trying my best to answer correctly please don't report my answer cause brainly mighty remove my account again.xd
