Answer: The balanced equation for the given reaction is
.
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side.
For example, 
Here, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
To balance this equation, multiply
by 2 on reactant side and multiply
by 2. Hence, the equation will be re-written as follows.

Here, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Now, there are same number of atoms on both reactant and product side. So, this equation is balanced.
Thus, we can conclude that the balanced equation for the given reaction is
.
Technically it's grp 1 elements...the answer is ribidium Rb
Heat can be absorbed or produced
Answer:
0.1667
Explanation:
Hello,
Dalton's law defines:

A total pressure is:

So, for A (solving for
in the previous equation, we get:

Since
, we obtain:
}
Best regards.
I believe the answer is gills
Fish's use gills to breathe, so tadpoles should use gills too
hope this helps
