scandium is a transition metal and shows a valency of 3.
Answer: Molarity of 
in the original sample was 1.96M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
Now put all the given values in the formula of molarity, we get
Thus molarity of in the original sample was 1.96M
1) The forward reaction is N2 (g) + O2 (g) → 2NO
(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.
2) The equiblibrium equation is
N2 (g) + O2 (g) ⇄ 2NO
3) Then, the reverse reaction is
2NO → N2(g) + O2(g)
Answer: 2NO → N2(g) + O2(g)
Answer:
A pregnant woman would consume 1.812 x 10⁻⁶ oz of mercury in a month if she ate the maximum recommended amount of fish.
Explanation:
0.302 oz mercury _____________ 1 x 10⁶ oz bluefish
x _____________ 6.00 oz bluefish
x = 1.812 x 10⁻⁶ oz mercury
A pregnant woman would consume 1.812 x 10⁻⁶ oz of mercury in a month if she ate the maximum recommended amount of fish.
This is a double replacement because both Copper and Sodium reacted with each other compounds , hence "double"
