Answer:
This reaction is characteristic to metal carbonates, which decompose when heated to form the oxide of the metal and carbon dioxide gas.
Explanation:
Just did it...
If excess carbon disulfide reacts with 450 mL of oxygen, 150 mL of carbon dioxide and 300 mL of sulfur dioxide gases would be produced respectively.
<h3>Stoichiometric calculation</h3>
The reaction between liquid carbon disulfide and oxygen is represented by the equations below:
The mole ratio of oxygen to carbon dioxide and sulfur dioxide produced is 3:1:2.
Thus, for 450 mL oxygen, 1/3 x 450 = 150 mL of carbon dioxide will be required.
Also for 450 mL of oxygen, 2/3 x 450 = 300 mL of sulfur dioxide will be required.

False.
Explanation:
Fusion reactions are not yet commercially viable because they require extremely high energies to initiate and sustain a reaction.
Answer:Chemical reaction
Explanation:
The main concept that must be applied to determine the coefficients (amount of each item) is that there must be equal amounts of each element on each side of the equation. We are not destroying or creating new atoms. In this case, the unbalanced reaction formula is:
B
r
2
+
K
I
=
K
B
r
+
I
2
There are a two problems we need to solve before it will be balanced:
There are two moles of Iodine atoms (
I
) on the right side of the equation, while there is only one mole on the right side.
There are two moles of bromine (
B
r
) atoms on the left side, while there is only one on the right.
Since there are two moles of bromine atoms on the left side, we need two moles on the right as well. We can do this by adding a coefficient of two to the
'
K
B
r
'
term in the equation. Our now modified equation looks like this:
B
r
2
+
K
I
=
2
K
B
r
+
I

There is one mole of Iodine atoms on the left, and two on the right. To fix this, we add a coefficient of two to the
'
K
I
'
term. The resulting equation is below.
B
r
2
+
2
K
I
=
2
K
B
r

Bonus step: We can also put ones in front of the coefficient-less species. This is like changing a phrase from "an apple" to "1 apple". It is the exact same thing, but makes it a little more clear sometimes. This would like like this:
1
B
r
2
+
2
K
I
=

Can you see that there is now an equal amount of each element on each side of the equation? That means that it is balanced.
