<h2>Answer:</h2>
Option A is correct;
A.) The atoms are arranged differently in each molecule
<h3>Explanation:</h3>
Water and hydrogen peroxide are made of the same elements: oxygen and hydrogen. However, hydrogen peroxide (H2O2) has 1 more oxygen than water (H2O).
Hydrogen peroxide is very unstable and breaks down readily into water and a single oxygen molecule.
And also the arrangement of atoms is different in each molecule.
All of these elements have an electron configuration<span> that ends with </span><span>s1</span><span>. Francium's properties have not been determined experimentally, because so far there has not been enough of it to experiment with </span>Sodium is group 1/IA, the alkali metals, on the periodic table. Therefore, the other elements in this group will have similar properties as sodium. These would include, lithium<span>, potassium, </span>rubidium<span>, and </span>cesium<span>.
Hope this is the answer

Answer:
option c is the correct one, we add some number like 2,3 or 4 in front of the reactant or product to make the number of the element(s) equal on both the product and reactant side
Pretty sure it is A. If an object has mass it’s gravity is zero
