Answer:
filtration
Explanation:
1.put the mixture in a beaker
2.add water to the beaker and stir to dissolve salt
3.filter using a filter paper to have sand as the residue
4.Evaporate the water to remain with salt crystals
Chromosomes have genes, and genes are segments of DNA.
Answer:
Al is oxidized while Ag is reduced.
Explanation:
The complete molecular equation is;
3Ag2S + 2Al --> 6Ag + Al2S3
Oxidation half equation;
2Al ------> 2Al^3+ + 6e
Reduction half equation;
6Ag^+ + 6e -------> 6Ag
Overall redox reaction equation;
2Al + 6Ag^+ ----->2Al^3+ + 6Ag
Hence; Al is oxidized while Ag is reduced.
Answer:The first thing you need to do here is to use the molarity of the solution to determine how many moles of sodium chloride you have in your sample.
As you know, molarity tells you the number of moles of solute, which in your case is sodium chloride, present in "1 L" of solution. This means that a "0.75 M" sodium chloride solution will contain 0.75 moles of sodium chloride for every "1 L" of solution.
Explanation:
Answer:
302°K = 28.85°C
Explanation:
Formula: °K - 273.15 = °C
0°C is equal to roughly 273°K
Simply plug it into the formula to find your temperature:
302°K - 273.15 = °C
°C = 28.85
