Is rubbing alcohol a mixture or solution?
It's a solution... but solutions are mixtures.
A chemist is making a solution that is to be 55 chlorine He has one solution that is 40 chlorine and another that is 65 chlorine He wants 100 liters of the final solution How much of each should?
Each should be 70
What will dissolve copper but not gold?
Iron is a highly reactive metal and most of the strong acids like sulfuric acid and nitric acid are able to dissolve it. Steel is less reactive than iron because it is an alloy but will get corroded and dissolved in nitric acid solution 50-70 %. See also the link below.
Is 70 percent Isopropyl rubbing alcohol a heterogeneous?
No, 70% isopropyl rubbing alcohol is a homogeneous mixture because it is a uniform solution of isopropyl alcohol with water. It has the same composition throughout and its components are evenly distributed.

How do you prepare 5 percent nitric acid solution from 55 percent nitric acid?
To solve this problem, we basically have 2 equations and 2 unknowns. The unknowns are the (volume of water) & the (volume of 70 wt%) nitric acid to add. * This problem will assume that you are interested in making 1 L (or 1000 mL) of 5 wt% nitric acid solution. Equation 1: (volume of water) + (volume of 70 wt% nitric acid) = 1000 mL Equation 2: mass of nitric acid / [mass of water + mass of 70 wt% nitric acid solution] = 0.05 (0.05 is 5 wt%) * Remember that mass = density * volume * Remember that 70 wt% nitric acid solution mean that for 100 grams (gm) of this acid, then there's 70 grams of HNO3 * Remember that density of 70 wt% nitric acid solution is 1.413 gm/cm^3 * Remember that density of water is 1 gm/cm^3 Equation 2 is now re-written as: [(density of 70 wt% nitric acid soln)*(volume of 70 wt% nitric acid)*0.70] / [(volume water)*(1gm*cm^3) + (volume of 70 wt% nitric acid)*(1.413gm/cm^3)] = 0.05 Solving for the 2 equations gives answer to the 2 unknowns: Answer: To make 1000 mL of 5 wt% nitric acid solution, add 1) 51.63 mL of 70 wt% nitric acid solution 2) 948.37 mL of water
How much pure acid should be mixed with 2 gallons of a 70 percent acid solution in order to get a 90 percent acid solution?
Set up. .70(2 gal) + X = .90(X + 2 gal) distribute 1.4 + X = .90X + 1.8 X = .90X + .4 .1X = .4 X = 4
What is the molarity of 70 grams of sulfuric acid in 280 mL solution.?
To find the molarity, first convert the mass of sulfuric acid to moles by dividing by its molar mass (98.08 g/mol). Then, calculate the molarity by dividing the moles of sulfuric acid by the volume of the solution in liters (280 mL = 0.28 L). Molarity = moles of solute / liters of solution.

What percentage of 200 is 70?
The answer is 35%. Solution: 70/200x100 =0.35x100 =35%
If you have a 70 percent solution of dextrose How many grams of dextrose is in 400ml of this solution?
In a 70% dextrose solution, 70% of the total weight is dextrose. To calculate the grams of dextrose in 400ml of this solution, you would multiply 400ml by 70% (or 0.70) to find the amount of dextrose present.
What is the difference between a concentrated acid and strong acid?
Concentrated acid means there's a lot of it; that is, a high concentration. By convention, "concentrated" means "straight out of the stock bottle," for some acids this is nearly pure and for others it's not (phosphoric acid is typically supplied as a solution that's about 70% w/w phosphoric acid, for example). Lab bottles labeled "dilute" usually contain a 6M solution unless otherwise specified. Strong acid means that it fully dissociates in water (at least the first proton, for multiprotic acids). Strong/weak and concentrated/dilute are completely different scales that have nothing to do with each other. * 18.3M sulfuric acid is strong and concentrated * 6M sulfuric acid is strong and dilute * Glacial acetic acid is weak and concentrated * 6M acetic acid is weak and dilute
What is the measurement of the base angles?

What is the symbol for the neutral atom that has 70 electrons?
Yb. Ytterbium, from the lanthanide series.
How much 95 percent alcohol must be used to prepare 1000 ml of 70 percent alcohol?
To prepare 1000 ml of 70% alcohol solution, you would need to mix 700 ml of 95% alcohol with 300 ml of water. Starting with a base of 95% alcohol ensures that the final solution will be at least 70% alcohol.
How many electrons are in one neutral atom of Yb - 173?
the atomic number of Yb is 70. So there are 70 protons and electrons
