It depends on what unit/subject you're looking at.
Because in physics, I know that if you are considering Newton's theory of particles, all particles technically go in a straight line from the original direction. BUT, if you're looking at the Wave of the Particle theory, then you would assume that particles do not necessarily follow the above b/c they follow the properties of a wave...
Lead reacts very slowly with dilute hydrochloric acid to give lead chloride<span> and </span>hydrogen<span> gas. </span>
<span>lead + hydrochloric acid —> lead chloride + hydrogen
Pb(s) + 2HCl(aq) —> PbCl2(aq) + H2(g)</span>
<span>Lead reacts very slowly with dilute sulphuric acid to give </span>lead sulphate<span> and </span>hydrogen<span> gas. </span>
<span>lead + sulphuric acid —> lead sulphate + hydrogen
Pb(s) + H2SO4 (aq) —> PbSO4(aq) + H2(g)</span>
<span>Lead reacts very slowly with dilute nitric acid to give </span>lead nitrate<span> and </span>hydrogen<span> gas. </span>
<span>lead + nitric acid —> lead nitrate + hydrogen
Fe(s) + 2HNO3(aq) —> Fe(NO3)2(aq) + H2(g)</span><span> </span>
I would tell you... but there is a lot of information... just type in online what you asked, and you will get lots of info.
540 nm is the answer ! can you help me out please ? it is a science question add me and message me :)
It pushes the positive ions together, the positive ions repel each other, causing the crystal to shatter
