The ionic compound NaCl is very soluble is water because it is a salt of a strong acid (HCl) and strong base (NaOH), making it a strongly ionic substance. This means that it completely dissolves/dissociates into the ions Na+ and Cl-. This is also the reason why it is considered a good conductor of electricity.
Answer: 37.5grams of Cu(NO3)2
Cu(1mol) + 2HNO3(2mol) —> Cu(NO3)2 + H2
<em>125 grams of Cu(1mol) reacts with 75 grams of HNO3(2mol)</em>
<em><u>HNO3 is the limiting substance, therefore, 75 grams is the limiting quantity.</u></em>
<em>Therefore, 2mol of HNO3 forms 1mol of Cu(NO3)2</em>
<em>75 grams of HNO3 forms...75grams x 1mol/2mol = 37.5 grams of Cu(NO3)2</em>

Answer:
5 km North
Explanation:
Displacement refers to the distance covered in a specific direction.
In this case,
Distance covered due north = 8 km
Distance covered due south = 3 km
Therefore;
If we take the distance towards north to be +8 km
The distance towards south to be - 3 km
Then;
Displacement = +8km + (-3km)
= + 5km
= 5 km North
Therefore;
The displacement is 5km towards North.
