Answer:
13=C
14=D
Explanation:
I cant explane the right formula but my answer is correct
True; Heilum is in Group 18 which are called “Noble Gases”
I believe the answer is B) :)
The balanced chemical equation for the reaction is
<h3>6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) + N₂(g) </h3>
From the question given above, we were told that:
solid cesium reacts with solid cesium nitrite to form solid cesium oxide and nitrogen gas.
The equation for the reaction can be written as follow:
Caesium => Cs
Caesium nitrite => CsNO₂
cesium oxide => Cs₂O
nitrogen gas => N₂
Caesium + Caesium nitrite —> Caesium oxide + Nitrogen gas
<h3>Cs + CsNO₂ —> Cs₂O + N₂</h3>
The above equation can be balance as follow:
Cs + CsNO₂ —> Cs₂O + N₂
There are 2 atoms of N on the right side and 1 atom on the left side. It can be balance by writing 2 before CsNO₂ as shown below:
Cs + 2CsNO₂ —> Cs₂O + N₂
There are 2 atoms of Cs on the right side and a total 3 atoms on the left side. It can be balance by writing 6 before Cs and 4 before Cs₂O as shown below:
6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) + N₂(g)
Now the equation is balanced

Oceanic crust is frequently pushed into the mantle near convergent plate borders, where it starts to melt. Granite, the rock that forms the continents, is formed as magma rises into and through the other plate.
Therefore, at convergent borders, oceanic and continental crust are annihilated.
<h3>What is a diverging plate boundary?</h3>
When plates are spreading apart, new oceanic crust is being created to fill the space left behind. Most divergent boundaries are observed around mid-ocean oceanic ridges (although some are on land).
The mountains would keep eroding over the next few million years, but since there wouldn't be any tectonic activity to renew them, they would gradually erode down to low rolling hills. This would result in far less fascinating geography and a flatter planet overall.
