<h3><u>Answer;</u></h3>
A: by counting up each individual atom and make sure the atom numbers are the same in the reactants and the products
<h3><u>Explanation;</u></h3>
- <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation. </u></em>Therefore, <em><u>the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, </u></em>that is the side of reactants and side of products.
- Thus, <em><u>any chemical equation requires balancing to ensure that the number of atoms of each element is equal in both sides of the equation</u></em>. Balancing is a try and error process that ensures that the law of conservation of mass holds.
- In this case, the balanced equation would be; 2Na +2H₂O → 2NaOH +H₂
Answer:
True
Explanation:
A convex mirror is a mirror whose outer bulging surface is the reflecting surface.
A convex mirror is used to see the distant objects and the image formed by the convex mirror is always erect and small. So, it is used as the rear view mirror.
It always forms a virtual, erect and diminished image of a real object.
It never forms a real image of a real object.
I think you always draw the gravity component. I'm not exactly sure though.
Answer:
The force is Centripetal force
