Lewis Structures of Ammonium Ion (RED) and Chloride Ions (BLUE) are attached below.
Lewis structures are those structures which shows the environment of electrons in a molecule. These structures basically depicts the bonding electrons and non-bonding electrons also known as Lone pair electrons.
In attached structure it can be seen that the ammonium ion is made when nitrogen atom is forming four single bonds with four hydrogen atoms and the formal charge on nitrogen becomes +1. While, in case of chloride ion the chlorine atom has four lone pair of electrons and has a formal charge of -1.
Fossil fuel is a collective term for buried, combustible deposits or organic materials formed from decayed plants and animals over millions of years ago that had been converted to different substances such as crude oil, coal, natural gas or heavy oils through heat and pressure exposure. They are sometimes known as mineral fuels.
The steps of fossil fuel formation are:
1. The plant uses energy found from its environment to form sugars and carbohydrates.
2. ANIMAL DEATH- for a fossil to form, an animal must die either in water or die out of the water. Water plays a vital role in the fossil formation because it helps in the preservation of the dead organism long enough for it to form.
3. BACTERIAL CONSUMPTION- bacteria eats away the soft parts and leaves the hard part such as the exoskeleton or bones. This hard body parts that are inherently resistant to bacterial erosion are the ones that forms into fossil.
4. SEDIMENTATION- this is the settling of dirt, dust or mud over these remains layer upon layer accumulate through the years
5. PERMINERALIZATION- layers of decomposed plants and animals are buried deep down the earth that they are squelched by the enormous mass of the earth creating intense heat and pressure.
6. After millions of years of heat and pressure, these buried materials transforms into chemicals known as hydrocarbons
7. These so called HYDROCARBONS can either be solid, liquid or gas. The solid form is known as coal. The liquefied form is the petroleum or crude oil. Lastly, the natural gas is the gaseous form.
Answer:
all objects will remain at rest, or will continue to move at a constant speed in the same velocity unless acted upon by an unbalanced force. This property is called interia
Explanation:
ANSWERS:
Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
