Answer: 12.5 moles NaNO3
Explanation: solution attached.
First balance predict the products
Na+ Mg( NO3)2 => Mg + NaNO3
Next balance the chemical equation
2 Na + Mg(NO3)2 => Mg + 2 NaNO3
Solve for the moles of Na
175 g Na x 1 mole Na/ 14 g Na
Next compare the mole ratios of Na and NaNO3 based from the balanced equation.
2 moles Na : 2 moles NaNO3
NaCl would form because it’s a single replacement reaction
Answer:
The stable ion the sulfur would form is the sulfide ion,
Explanation:
When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.
