Hope this helps you
The particles are moving fastest in Region D) 5.
As temperature increases, so does the average kinetic energy (speed) of the molecules.
Answer:
NaNO3
Explanation:
sodium= Na
Nitrogen= N
and there's 3 oxygens = O3
<span>The
list of phases of H2O that is arranged in order of increasing entropy is from
solid then liquid then gas. Gaseous water has the most entropy because of the
random movement of water molecules. And Solid having the least entropy because the
water molecules are arranged in a specific order.</span>
Answer:
3.6 grams of NaCl are needed
Explanation:
Percent solution are solutions whose concentrations are expressed in percentages. The amount(either weight or volume) of a solute is expressed as a percentage of the total weight or volume of solution. Percent solutions can either be expressed as weight/volume % (wt/vol % or w/v %), weight/weight % (wt/wt % or w/w %), or volume/volume % (vol/vol % or v/v %).
A 6.0% wt/wt % solution contains 6 g of solute in 100 g of solution
Therefore, a 100 g solution contains 6.0 g of solute.
60 g of 6.0% solution will contain 60 g solution * 6.0 g solute/ 100 g solution
Mass of NaCl present = 3.6 g of NaCl
