1. Write the balanced equation for the decomposition of hydrogen peroxide
earnstyle [38]

The balanced equation for the decomposition of hydrogen peroxide is H₂O₂(aq)→2H₂O(l)+O₂(g).

<h3>What is decomposition reaction?</h3>

Decomposition reactions are those reactions in which a compound will decompose into small molecules.

Hydrogen peroxide will decompose into water molecule and oxygen gas, balanced chemical equation will be represented as:

H₂O₂(aq) → 2H₂O(l) + O₂(g)

Where all atoms are present in equal quantities on both side of the equation.

Hence balanced decomposition reaction of H₂O₂ is H₂O₂(aq)→2H₂O(l)+O₂(g).

when a number in scientific notation contains a significant zero, is that zero also significant in the expanded notation? give t
AlexFokin [52]
I believe you are referring zero as the exponent. <span>Any number (except 0) with exponent 0 is defined to mean 1.
</span>

For one thing, there is a rule: 

<span> a^m/ a^m = a^m-m = a^0

</span>But (when a is not equal to <span>0),
</span>
a^m/ a^m = 1

Therefore, we must define a^0 as 1.

Write a balanced chemical equation for the standard formation reaction of solid chromium(iii) nitrate crno33 .
Drupady [299]

Explanation:

Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.

Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.

2Cr(s)+3N_2(g)+9O_2\rightarrow 2Cr(NO_3)_3(s)

A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate

Cr(s)+\frac{3}{2}N_2(g)+\frac{9}{2}O_2\rightarrow Cr(NO_3)_3(s)
