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>
Answer:
11.) Radio
12.) Microwave
13.) Infrared
14.) Ultraviolet
15.) X-Ray
16.) Gamma Ray
<u>Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.</u>
<u></u>
Answer:
Positively or negatively charged (im not 100% sure but the question says "as they have lost or gained electrons") because atoms that gain electrons are called anions and atoms that lose electrons are called cations. atoms losing electrons are positively charged and atoms gaining electrons are negatively charged.
I'm not sure if this helps a lot but now you know a few things about ions :)
21: potassium has 20 neutrons
22: is d
