Missing question:
KNO₃(s) + energy ⇄ K⁺(aq) + NO₃⁻(aq)
Which change causes the equilibrium to shift?
(1) increasing pressure .
(2) increasing temperature.
(3) adding a noble gas.
(4) adding a catalyst.
Answer is: (2) increasing temperature.
<span>This is endothermic reaction, because heat is included as reactant.
According to Le
Chatelier's Principle, the position of equilibrium moves to counteract the
change, because heat (temperature) is increased, system consume that heat, so
equilibrium is shifted to right, by decreasing concentration of reactants and
increasing concentration of product.</span>
Well ionic compounds are brittle because similar charges repel, which causes them to break usually occurring when a force is applied, like a hammer strike.
Answer:
The CN double bond and triple bond are stronger than the corresponding CC bonds
Explanation:
Because this acid dissolves the enamel on the tooth creating holes or cavities
M (NaCl) = n × M = 3.75 × 58.5 =
219.375 g
M (NaCl) = 23 + 35.5 = 58.5 g/mol
