You first add the manganese and exchange the number of electrons needed with the hydroxide. While the hydroxide needs only 1 electron the manganese needs 4, so after you exchange the electrons the manganese will be just 1 atom while the hydroxide is 4. Mn(OH)4
Answer:
d = 3 g/cm³
Explanation:
Given data:
Mass of stone = 27 g
Volume of water = 10 cm³
Volume of water+ stone = 19 cm³
Volume of stone = ?
Density of stone = ?
Solution:
Volume of stone = total volume - volume of water
Volume of stone = 19 cm³ - 10 cm³
Volume of stone = 9 cm³
Density of stone:
d = m/v
d = 27 g/ 9 cm³
d = 3 g/cm³

Doubling the mass doubles the energy, while doubling the velocity quadruples it. Your question is basically about order of operations; the exponent only applies to the variable it's immediately on. As you note, you'd have to put parentheses to make it cover the
m as well. We say that energy is linear in mass, but quadratic in velocity.
