Answer:
<h2>Density = 3.9 g/ mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 43 g
volume = 11.1 mL
Substitute the values into the above formula and solve for the density
That's
We have the final answer as
Density = 3.9 g/ mL to one decimal place

I got it right on edjenuity
Answer:
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
Explanation:
we have aluminum that is added to nickel (ii) nitrate solution. Nickel (ii) means here nickel having electron charge of +2 . NO₃ having electron charge -1. So nickel nitrate solution be (NO₃)₂
Aluminium on reaction replaces nickel and form Aluminium Nitrate with some amount of nickel. After balancing both side
2Al + 3Ni(NO₃)₂ = 3 Ni + 2 Al (NO₃)₂
