Answer:
Terms we might use to describe timbre: bright, dark, brassy, reedy, harsh, noisy, thin, buzzy, pure, raspy, shrill, mellow, strained. I prefer to avoid describing timbre in emotional terms (excited, angry, happy, sad, etc.); that is not the sound quality, it is its effect or interpretation

Answer:
the amount of reactants is always directly proportional to the product
Explanation:
The balanced chemical equation will b
N2H4 + 2 H2O2-> N2 + 4H2O
so first of all we have to find the limiting reactant.
so for this
9.24 g H2O2 ( 1 mol / 34.02 g mass of H2O2 )
= 0.27 mol H2O2
Now
6.56 g of N2H4 ( 1mol / 32.06) = 0.20 mol N2H4
so from the above reaction we found 1:2 ratio of the reactants
so the limiting reactant is hydrogen peroxide. by using this we will find the amount of N2 produced.
so that will be
<span>0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2)
=1.89 g N2
hope it helps</span>
Answer: Another useful feature of the periodic table is that most tables provide all the information you need to balance chemical reactions at a glance. The table tells each element's atomic number and usually its atomic weight. The typical charge of an element is indicated by its group.
