There are four sodium atoms in the product.
A reaction equation is said to be balanced when the number of atoms of reactants are equal to the number of atoms of products according to the balanced reaction equation.
Given the reaction between sodium metal and oxygen, the reaction could be written as; 2Na(s) + O2(g) ----> 2Na2O(s). We can see that there are four sodium atoms in the product.

Answer: 6.3 * 10^15
Explanation:
wavelength = speed of light / frequency
so rewriting the equation gives frequency = speed of light / wavelength
so 3.0 *10^10 / 4.76 * 10^-6 = 6.3 * 10^15
On four, in real life, she could put it in a strainer and put a bowl below the strainer. The liquid will fall through and into the bowl, but the solids will stay in the strainer. That may not be correct in terms of your reading because I don't know what the reading is.
Answer:
yes
Explanation:
Lavoisier's finding laid the foundation for modern chemistry and revolutionized science. The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth. Most elements come from fusion reactions found only in stars or supernovae.
<span>If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. For this, a neutralzation reaction happens where amount of acid should be equal to amount of base. Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.</span>
