Answer:
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
Hopefully this is what you needed
Balanced equation : 2Na+I₂⇒2NaI
<h3>Further explanation
</h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
• 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
• 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
• 3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
Na+I₂⇒NaI
aNa+bI₂⇒NaI
Na, left=a, right=1⇒a=1
I, left=2b, right=1⇒2b=1⇒b=0.5
Equation becomes :
Na+0.5I₂⇒NaI x 2
2Na+I₂⇒2NaI
A gas is assumed to behave ideally if it follows the following assumptions:
Gas particles are very tiny so their volume is negligible. So they are considered that do not have a volume.Gas particles move at a constant motion, which means that they do not collide.Gas particles do not interact with each other, therefore, there will be no attraction or repulsion between each other.These are the main points of difference between an ideal gas and a real gas.
For a real gas, all these points are not valid, therefore:
Gas particles occupy a space and therefore have a volume.Gas particles collide with each other and their motion tends to speed up or slow down.Gas particles interact with each other.
