Answer:

Cr⁺² = 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d²

Explanation:

As Chromium atom has 24 electrons in its shells. When it lose 2 electrons from its valance shell, it become chromium ion. Thus chromium ion has 22 electrons.

Fill electrons in shells accordingly.

A 29.00 mL sample of an unknown H3PO4 solution is titrated with a 0.130 M NaOH solution. The equivalence point is reached when 2

beks73 [17]

I am first assuming that you want the molarity of the acid. Use the formula $M_{a} V_{a} = M_{b}V_{b}$ which is the titration formula. M is molarity (a is of acid and b is of base) and V is volume in mL (a is of acid and b is of base). Plugging in gives us $(29 mL)(M_{a}) = (0.130 M)(27.73 mL)$ . Solving gives us $M_{a} = 0.124 M$
