The motion of atoms decrease when there is a decrease in velocity and kinetic energy that is decrease in temperature. this occurs during freezing and condensation.
I think it will be letter A tbh
Hope this helps you out
<h3>Answer:</h3>
Fe(NO₃)₃(aq) + 3LiOH(aq) → Fe(OH)₃(s) + 3LiNO₃(aq)
<h3>
Explanation:</h3>
- The equation between LiOH and Fe(NO₃)₃ is given by;
Fe(NO₃)₃(aq) + LiOH(aq) → Fe(OH)₃(s) + LiNO₃(aq)
- This is an example of a double displacement reaction.
- A double displacement reaction is a type of reaction in which two compounds reacts by exchanging cations or anions to form new compounds.
- To balance an equation we put appropriate coefficients on reactants and products for the atoms of each element to be equal.
- Therefore, the complete balanced equation for the reaction is given by;
Fe(NO₃)₃(aq) + 3LiOH(aq) → Fe(OH)₃(s) + 3LiNO₃(aq)
1.2 x 10^3 is equivalent to 1200. 1 & 2 are signficant because they are real numbers, the 0's do not play a role in significant figures in this setup particularly because no decimal point is given. However, if a decimal point was present it would have 4 signficiant digits and you equation would look something more like, 120.0 x 10^1.
