<em>Answer:</em>
- At 60 centigrade, the kinetic energy of the substance will be greatest.
<em>Explanation:</em>
As we know, the kinetic energy of substance is directly proportional to Temperature.
The total Kinetic energy can be calculated as follow
K.E = 3/2 n.R.T
From the equations, it is cleared that Temperature is directly proportional to temperature.
Your answer is the element of S I think.
1) H+(aq) + Cl-(aq) + Li+(aq) + OH-(aq) --> H2O(l) + Li+(aq) + Cl-(aq) H+(aq) + OH-(aq) --> H2O(l) (net ionic equation) because Li+ , Cl- are the spectators. 2) Mg2+(aq) + S2-
