What is the ratio of Fe3+ ions to O2- ions in a neutral compound? 1:2 2:1 2:3 3:2,

1 answer:

8 0

<span>The answer is 2:3. Because the lowest common denominator of 2 and 3 is 6, we find that for every 2 Fe3+ ions, we would need 3 O2- ions to neutralize the charge. The other answers do not fit this idea, as the math doesn't then add up to come to a neutral charge.</span>

If you add 4.00 mL of pure water to 6.00 mL of 0.750 M NaCl solution, what is the concentration of sodium chloride in the dilute

Naddik [55]

Answer:

D) 0.450 M

Explanation:

Given data

Initial volume (V₁): 6.00 mL

Initial concentration (C₁): 0.750 M

Volume of water (VH₂O): 4.00 mL

Final volume (V₂): V₁ + VH₂O = 6.00 mL + 4.00 mL = 10.0 mL

Final concentration (C₂): ?

We can determine the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 0.750 M × 6.00 mL/10.0 mL

C₂ = 0.450 M

Identify the spectator ions in the following molecular equation.

SOVA2 [1]

We can rewrite the equation KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq) into its net ionic equation into
K+ + Br- + Ag + + NO3- = AgBr + K + NO3-only aqueous solutions can dissociate. Spectator ions are present in both sides, hence these are K+ and NO3-. THe rules of assigning oxidation numbers is to identify the number of valence electrons of elements and may be arbitrary depending on the charge of the molecule.
