Answer:
The Lewis dot structure is not correct
Explanation:
Each atom ought to be surrounded by eight electrons or two electrons according to the octet rule. We now need to closely examine the structure to see if it fits into this description.
All the atoms in the molecule have the correct valence except the hydrogen which is directly attached to the oxygen.
The positive charge ought to mean that more than two bonds were formed between hydrogen and oxygen which is clearly not the case here.
Thus, the hydrogen atom attached directly to oxygen does not display the correct valence.
Describe the trends in properties of chlorides across period 3 .Their formula .Their state .Their volatility .Their structure .The ph of aqueous chloride solution
Answer:
See explanation
Explanation:
Period 3 elements include; Na, Mg, Al, Si, P,S,Cl and Ar
Across the period, the chlorides of the elements change from solid to gas. The chlorides of metals are solid while the chlorides of non metals are gaseous.
Also, the chlorides become more volatile across the period. The formulas of the chlorides change from MCl to MCl2 to MCl3 to MCl4, MCl5 and MCl6 respectively across the period where M is a period 3 element.
The pH of the solutions of chlorides of period 3 elements change from neutral to acidic across the period. The pH of the chlorides of metals are neutral while the chlorides of the nonmetals usually yield acid solutions.
A seais usually defined as A.A body of freshwater that is not connected to the ocean B. A body of freshwater that is connected to the ocean C. A body of salt water that is not connected to the ocean D. Body of salt water that is connected to the ocean
Answer:
D. Body of salt water that is connected to the ocean
Explanation:
An ocean is a body of salt water which covers approximately 70% of the Earth's surface. About 97% of the Earth's water is comprised of ocean and as such it is the most prominent and defined feature of the Earth. There are basically four (4) categories of an oceanic basin and these are;
1. The Pacific ocean.
2. The Artic ocean.
3. The Atlantic ocean.
4. The Indian ocean.
A sea is usually defined as a body of salt water that is connected to the ocean and are surrounded (enclosed) by land partially.
Basically, a sea is formed where a land and an ocean meet and as a result, an ocean is usually bigger than a sea.
Some examples of seas around the world are Red sea, Mediterranean sea, Sargasso sea, Caribbean sea, Baltic sea, Caspian sea, Chuckchi sea, etc.

Why do we not see a solar and lunar eclipse every lunar cycle?
Answer:
Explanation: We don't see lunar eclipses every cycle because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. And when an eclipse occurs the earth passes directly between Sun and Moon.
