Answer: -Ionic solids are brittle and hard because the electrostatic attractions in the solid again hold the ions in definite positions. Explanation; -Ionic solids are rigid because the multiple interactions between oppositely charged ions hold the charged particles in relatively fixed positions.
Hope this help!!!!!!
Answer:
NaOH + HCl = NaCl + H2O
(3.612 moles of HCl) x (1/1) x (39.9971 g/mol) = 144.5 grams
So answer B.
Explanation:
NaOH + HCl = NaCl + H2O
(3.612 moles of HCl) x (1/1) x (39.9971 g/mol) = 144.5 grams
Answer:
Rate law:
Integrated Rate Law:
Explanation:
We can see that the graph of time is linear compared to and the reaction is second order hence we get the rate law from .
The integrated rate law for second order is where A is .
The slope of the graph w.r.t time is equal to k. The slope of the graph from the table is 0.014 which is equal to k.
