Vanadium (II) oxide with Iron (III) oxide results in Vanadium (V) oxide and Iron (II) oxide. Balance this equation
evablogger [386]

Answer:

2VO + 3Fe2O3 —> V2O5 + 6FeO

Explanation:

The skeletal equation for the reaction is given below below:

VO + Fe2O3 —> V2O5 + FeO

We can balance the equation above by doing the following:

There are 2 atoms of V on the right side and 1 atom on the left side. It can be balance by putting 2 in front of VO as shown below:

2VO + Fe2O3 —> V2O5 + FeO

Now, we have a total of 5 atoms of O on the left and 6 atoms on the right side. We can balance it by putting 3 in front of Fe2O3 and 6 in front of FeO as shown below:

2VO + 3Fe2O3 —> V2O5 + 6FeO

Now, we can see that the equation is balanced

Which best describes a chain reaction associated with a nuclear reaction? Neutrons released during a fusion reaction cause other
atroni [7]
The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons <span>released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.</span>

A+uniform+cube+is+subjected+to+volume+expansion. +if+each+side+is+decreased+by+1%,+then+bulk+strain+is
laiz [17]

A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.

<h3>What is Volume?</h3>

Volume is the space occupied by a three-dimensional object.

<h3 />

Given that, the side cube is l, then

volume V = l³

\dfrac{\Delta V}{V} = \dfrac{3D1}{1}

For change in volume

% Change in volume = 3× % change in length

= 3 × 1%

Hence, bulk strain = 0.03.



Thus, the bulk strain is 0.03.
