<u>Answer:</u>
<em>Latest take an example to understand how </em><em>balancing of chemical reaction</em><em> is done that is assuming the reaction between iron as well as </em><em>oxygen which reacts to form rust.</em>
<u>Explanation:</u>
For this we would simply right the reactant and product that is expected. Then we would see the number of molecules of each element present on either side.
If in the reaction the element’s molecules are the same on both sides then the reaction would be correct and if not then we have to apply trial and error method to balance the equation such that the number of molecules of each element is equal on both sides of the reaction.
Answer:
d
Explanation:
It is 1+ because when the periodic table is drawn well into there groups become cations
A. Breaking Bread, because you can rip or cut it and it is still bread.
hope that helps :)
The number of oxygen atoms = 3
Mass = 24 g
<h3>Further explanation</h3>
The formula of a compound shows the composition of the constituent elements
CaCO₃ is composed of 3 types of elements, namely Ca, C and O
The amounts of each of these elements in the compound CaCO₃:
So the number of oxygen atoms = 3
mass of Oxygen :

2.6x10negative4power
2.6x10^-4
