<span>Hello!
The statement that best proves that the law of conservation is obeyed during this process is that </span><span>The total mass of oxygen and carbon is equal to the total mass of carbon dioxide.
The chemical equation for the combustion reaction of coal in the carbon cycle is the following one:
C(s) + O</span>₂(g) → CO₂(g)
<span>
From this simple chemical equation, we can conclude that if the Law of Conservation of Matter is obeyed in this reaction, the sum of the initial masses of Carbon and Oxygen before the reaction will be equal to the total amount of Carbon Dioxide formed by it, because they sum up to produce Carbon Dioxide.
Have a nice day!</span>
Answer:
It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.
Weather is the state of the atmosphere at any given time and place.
Climate is the long-term average of the weather in a given place
Answer:
were learning about this right now can you help me with the wuestion 8th grade sucks.
Explanation:
Answer:
Option C = three electrons are gained, making N⁻³
Explanation:
Nitrogen is present in group 5A.
Its atomic number is seven.
It have five valance electrons.
Its electronic configuration is N₇ = [He] 2s² 2p³
In order to complete the valance shell or 2p subshell nitrogen must gain three more electrons.
When an atom gain the electrons anions are formed and negative charge is created on it.
When an atom lose its valance electrons cation is formed and positive charge is created.
That's why when nitrogen gain three electrons to complete the valance shell N⁻³ is formed.
