Answer: A is a decomposition reaction, and B is a synthesis reaction
Explanation: the first equation shows the reactant breaking up into 2 parts aka decomposition and equation 2 shows the reaction being combined into one part, aka synthesis. hope that helps!
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°
Explanation: Formula used to calculate the hybridization:
![{\text{Number of electron pairs}} =\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom i.e. carbon = 4
N = number of monovalent atoms bonded to central atom = 2
C = charge of cation = 0
A = charge of anion = 0
For 
![{\text{Number of electron pairs}} =\frac{1}{2}[4+2-0+0]=3](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5B4%2B2-0%2B0%5D%3D3)
The number of electron pairs are 3 which means that the hybridization will be 
and the electronic geometry of the given molecule will be trigonal planar.
The bond angle in this electronic geometry is 120°
The structure of phosgene is attached below.
Answer:
X₃Z₂
Explanation:
A metal ion (X) with a charge of 2+ = X²⁺
nonmetal ion (Z) with a charge of 3- = Z³⁻
In a neutral compound, the charges but balance each other to remain neutral. However in this case, the charges are not balanced.
A simple way to make the charges balance is by tweaking the number of the ions present in the compound.
We do this by multiplying the metal ion with 3 and the non metal ion by 2.
That way we have;
Metal ion = 3X2⁺ (Total charge - 6⁺)
Non metal ion = 2Z3⁻ (Total charge - 6⁻)
The charges are now balanced. The formular of the compound is;
X₃Z₂
Answer:
Desertification mainly impacts land resources.
Point and nonpoint sources refer to types of water pollution.
The process of people moving to cities, called urbanization , greatly impacts land, air, and water resources.
The burning of fossil fuels can cause smog and acid rain.
