Au^2S^3+ 3H^2 = 2Au + 3H^2S
When aqueous solutions of table salt and silver nitrate are mixed a white solid forms. This solid is called a precipitate. <span>A </span>precipitate<span> is an insoluble solid that emerges from a liquid solution. </span>The process of forming this solid is called precipitation.
Sulfur (16S) has 23 known isotopes with mass numbers ranging from 27 to 49, four of which are stable: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%).
In your problems the possible solution is this one:
<span><span>F<span>fr</span></span>=<span>μk</span><span>FN</span>=<span>μk</span>mg</span><span>0.5(50000kg)(−9.8<span>m<span>s2</span></span>)</span><span>=−245000N</span>
<span>a=F/m</span><span>−245000N/50000kg</span><span>=−4.9<span>m<span>s2</span></span></span><span>t=<span><span>v−<span>v0</span></span>a</span></span><span><span>0−10<span>ms</span></span><span>−4.9<span>m<span>s2</span></span></span></span><span><span>=2s
I hope you understand and satisfied with my answer</span></span>
