Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O)
Answer:
electromagnetic
Explanation:
because the sun naknometer are know as infrared Ray's and carry lower levels of energy wthat is sunlight
Answer:
No, it is not balanced.
The balanced equation is: Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.
Explanation:
- To balance the equation, you should apply the law of conservation of mass for the equations.
- The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
- For the given equation: <em>Zn(OH)₂ + NaOH → Na₂ZnO₂ + H₂O.</em>
The no. of Na atoms in reactants side is 1 but in products side is 2.
The no. of H atoms in reactants side is 3 but in product side is 2.
<em>So, the equation is not balanced.</em>
<em></em>
- The balanced equation is:
<em>Zn(OH)₂ + 2NaOH → Na₂ZnO₂ + 2H₂O.</em>
<em></em>
- The no. of all atoms is the same in both of reactants and products side.
Zn (1), O (4), H (4), and Na (2).
