What is mixing index?
Mixing index is defined as the number whic shows that weather the particle are mixed uniformally or not.
How can you extract gold?
Gold is undoubtedly the most desirable among precious metals. You may extract gold in a number of ways, after grinding the gold bearing mass so that maximum gold surface is exposed. To mention few (all under a hood): a. The aqua regia solution obtained by mixing 3 parts of concentrated HCl with one part concentrated HNO3 b. The cyanide process using KCN or NaCN solution and air bubbling c. Same but using (carefully) H2O2 instead of air d. Iodine solution in KI solution e. Chlorine obtained by mixing HClO solution with HCl solution f. Sodium thiosuphate, Na2S2O3, solution, with air bubbling Stirring and or heating will help in most cases
What best describes what the pH number indicates about a solution?
How acidic the solution isthe number of H+ ions in the solution
What distinguishes a solution?
The number of hydrogen ions is what distinguishes a strong solution from a weak solution.
What is the molarity of the solution obtained by diluting 12.500 mL of a 5.42 M calcium bromide solution to 500.0 mL?
For problems like these, (dilution/concentration) it is usually best to find out how many moles of solute you are working with. To do this, multiply the number of Liters you have by the Molarity (mol/L) of the solution:(.0125L)*(5.42M)= .0678mol (12.5mL=.0125L because there are 1000mL in 1L)Now that we know how many moles of calcium bromide we have, we can find the molarity of the new solution if it is .5L. Because molarity is just mol/L, we can just divide the amount of moles by .5, which gets us:(.0678mol)/(0.5L)= 0.136M
How many ounces of a 25 percent alcohol solution must be mixed with 9 ounces of a 30 percent alcohol solution to make a 28 percent alcohol solution?
Let a be the number of ounces of 25% alcohol required. Then, 25a + (30x9) = 28(9 + a) 25a + 270 = 252 + 28a 3a = 18 a = 6 Then 6 ounces of 25% alcohol + 9 ounces of 30% alcohol produces 15 ounces of 28% alcohol.
Can alcohol mix more easily with fat than water?
no alcohol can not mix more easily with fats than water. this happens because in water- alcohol mixing hydrogen bonding is involved which mixes water readily with alcohol....while during fats- alcohol mixing there is no involvement of hydrogen bonding or any other stronger bonding due to oxidation which causes fats to lose its effective number of hydrogen.
A solution is made by dissolving 19.52 g of SnF2 into enough water to make 770 mL of solution What is the molarity of the solution?
the molarity is found by: 19.52g/770mL x 1 mole/156.7g x 1000mL/1L=0.618 mole i got 156.7g by using the chemical makeup of the solution SnF2: Sn's atomic number being 118.7 and rounding F's atomic number to 19.
How many gallons of a 90 percent antifreeze solution must be mixed with 90 gallons of 15 percent antifreeze to get a mixture that is 80 percent antifreeze?
Let M equal the gallons of the 90% mixing solution. Let F equal the gallons of the final solution. So:90 + M = F.Also, the number of gallons of pure antifreeze in the final will equal the sum of the gallons of antifreeze in the two mixing parts:Original solution: ( 90 gal )*(0.15) = 13.5 gal [0.15 represents 15%]Mixing solution: M*0.90Final solution: F*0.80So 13.5 + M*0.90 = F*0.80Now you have 2 linear equations and 2 unknowns, you can solve for M & F, using your favorite method: M = 585 and F = 675. Add 585 gallons of the 90% to get 675 gallons of 80% solution.
What does 5wt mean in oil weights?
This is the number of grams of solute in 100 grams of solution. As an example, a 5%w/w solution in water is prepared by dissolving 5 grams of solute in water and then adding further water with mixing until the final weight is 100 gram.
How do you converte militer to Liter?
1000ml is a litre Number of litres multiplied by 1000 is the amount of ml

What is A number that makes a equation true?
The solution set is the answers that make an equation true. So I would call it the solution.
What best describes what the pH number indicates about a solution?
How acidic the solution isthe number of H+ ions in the solution
How do solutions dilute?
Solutions get diluted whenever there is an increase on volume but the number of moles of your substance remains the same. Eg: if I have 1 mole of NaCl in 1000ml, then I add 1000ml of water, then net volume is 2000ml but the number of moles of NaCl present is still 1 so the conc went from 1 mol/L to 0.5 mol/L. It was diluted!
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
