Answer:
Ammonium carbonate is a neutral molecule. Charge on NH4 is +1 , so on (NH4)2 is +2 ( +1 * 2) ,lets take the charge on C to be x and O is -2 , so on O3 is -6 (3*-2). Therefore x= + 4. Hope it helps.

A strontium ion, Sr2+, contains 36 electrons, which is the same number as in the noble gas Krypton, Kr, and is therefore isoelectronic.

The new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M
HOW TO CALCULATE CONCENTRATION:
- The concentration of a diluted solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration
- C2 = final concentration
- V1 = initial volume
- V2 = final volume
- According to this question, a solution of NaCl has 400.0 mL of a 0.425 M solution and diluted to 900.0 mL. The new concentration is as follows:
400 × 0.425 = 900 × C2
170 = 900C2
C2 = 170 ÷ 900
C2 = 0.189M
- Therefore, the new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M.
