The complete and <span>balanced equation for this single-displacement reaction would be written as follows:
</span><span>Li+NaOH--> LiOH + Na
In this reaction, lithium replace sodium in the compound sodium hydroxide forming lithium hydroxide and sodium metal as products. Hope this answers the question.</span>
Answer:
Molecules
Explanation:
If you had more than one atom chemically bonded together, then regardless of the types of atoms that are bonded, you're going to have a molecule regardless.
Scientists change the independent variable; The dependent variable is the one that reacts to the independent variable.
Answer: 3.01 x 10^24 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of SI = 6.02 x 10^23 atoms
5.0 moles = Z atoms
To get the value of Z, cross multiply:
(Z atoms x 1 mole) = (6.02 x 10^23 atoms x 5.0 moles)
Z atoms•1 mole = 30.1 x 10^23 atoms•moles
Divide both sides by 1 mole
Z atoms•1 mole / 1 mole = 30.1 x 10^23 atoms•moles / 1 mole
Z = 30.1 x 10^23 atoms
[Place Z in standard form
So, Z = 3.01 x 10^24 atoms]
Thus, there are 3.01 x 10^24 atoms in 5.0 moles in SI
