12. 2.9 g= 0.0029 13. 14.7 L = 14700 ml
14. The chemical formula of magnesium hydroxide is Mg(OH)2, and its molar mass is 58.32 g/mol.
Explanation:
Answer:
1.06 M
Explanation:
Lets answer this question using the definition for molarity of a solution, M.
M = mol of solute/ Volume of solution in L
We are adding more moles of NaOH to a solution which is already 2.40, so the final number of moles are
25 g x 1 mol / 40 g/mol = 0.625 mol
mol NaOH in 1.5 L of 2.40 M NaOH:
1.5 L x 2.40 mol/L = 3.6 mol
Total # mol = 0.625 mol + 3.6 mol = 4.23 mol
The final volume is 4.00 L so the new molarity is:
M = 4.23 mol / 4 L = 1.06 M

Answer: An existing theory is modified so that it can explain both the old and new observations.

Answer:
Livermorium is a radioactive, artificially produced element about which little is known. It is expected to be a solid and classified as a metal. It is a member of the chalcogen group. Livermorium has four isotopes with known half-lives, all of which decay through alpha decay
