Using the periodic table only, arrange the elements in each set in order of increasing EN:
madam [21]

Oxygen to sulfur is less polar than comparable bonds to oxygen because sulfur is less electronegative than oxygen.

In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. In groups, electronegativity rises from bottom to top; across periods, it rises from left to right. Fluorine is the element with the greatest electronegative charge, whereas francium has a very low electronegative charge. Within a set of elements, electronegativity values drop from top to bottom. Moving from left to right along a period improves electronegativity. This is caused by a decrease in atomic size and a rise in nuclear charge, which allows a shared electron pair to be more attracted to one another.

Using the appropriate conversion factors in #2, convert 248 eggs into dozen of eggs
Marina CMI [18]

Answer:

20.67 dozen of eggs.

Explanation:

One dozen egg = 12 eggs

For 248 eggs.

we will divide the 248 by 12.

248/12

20.7

Thus 20.7 dozen eggs are equals to 248 eggs.

It can be confirm by multiplying the 20.7 with 12.

20.67 ×12

248.0

So, 20.67 is correct answer.

Draw the Lewis structures of N2H4, N2H2, and N2.Draw the molecules by placing atoms on the grid and connecting them with bonds.
tamaranim1 [39]

Answer:

The structures are shown below

Explanation:

To draw the Lewis structure, we must place the central atom with its valence electrons surrounded by the other atoms, with their valence electrons, then, using lines, we put the bonds (simple line for 1 pair sharing, a double line for 2 pairs sharing, and triple line for 3 pairs sharing).

For N₂H₄, the two nitrogens are bonded together and with two hydrogens, Nitrogen has 5 valence electrons, and hydrogen 1 valence electron, so, 3 bonds will be done by nitrogen, so there will one lone pair in the structure for each nitrogen, and none for hydrogen. The structure is shown below.

For the N₂H₂, the nitrogens are bonded together, sharing two pairs of electrons, and are each one is bonded to a hydrogen, sharing one pair of electrons. Both nitrogen, then, has one lone pair of electron. The structure is shown below.

For the N₂, the two nitrogens are sharing three pairs of electrons, and both have one lone pair of electron. The structure is shown below.

Which process takes place when large rocks crumble due to oxidation?
Zielflug [23.3K]

D) chemical weathering​

Explanation:

When large rocks crumble due to oxidation, chemical weathering has taken place.

  • Weathering is an essential process on the earth. It is driven strictly by the external heat engine.
  • Weathering is defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.
  • When rocks decompose chemically, their structure weakens because they undergo chemical reactions.
  • During oxidation, oxygen combines with rock materials to form new products. This one process of chemical weathering.
  • Other examples are hydrolysis, carbonation, hydration e.t.c
