How would one prepare 10 ml of a 25 M HCI solution if 1 M HCI was available?
To prepare a 10 ml of a 25 M HCl solution, you would need to dilute the 1 M HCl solution by a factor of 25. You will need 0.25 ml of the 1 M HCl solution and 9.75 ml of solvent (usually water) to make a total volume of 10 ml for the 25 M HCl solution.

How many amps does a hair dryer use with 25 volts 60 hz and 1500 watts?
Amps = Watts / (Volts x Power Factor). Now a hair dryer has a motor and a resistive heater so if we assume a PF = .8 the answer is: 1500 / 20 = 75 amps. Since it is unlikely that you have a 75 amp hair dryer you must mean 125 volts. The answer for that would be 1500 / 100 = 15 amps which is still high, but believable. If we assume a Power Factor of 1 and ignore the motor contribution to Power Factor we have 1500 / 125 = 12 amps.
How is 25 inch converted into meter?
To convert 25 inches to meters, you can use the conversion factor of 1 inch being approximately equal to 0.0254 meters. Therefore, 25 inches is equal to 25 * 0.0254 = 0.635 meters.
How would you factor 4a2 plus 25?
4a2+ 25 does not factor over the real number field. In the complex numbers , it factors as (2a +5i)(2a - 5i). This is because i2 = -1, so 4a2 + 25 = 4a2 - (- 25) = 4a2 - 25(-1) = 4a2 - 25i2
How do you factor 4a2 - 8a - 5?
(2a + 1)(2a - 5)
What is the greatest common factor of 4a2 2a?
2a
What is the factor of 4a2-17a 4?
(4a - 1)(a - 4)
How do you factor 4a2 -4a - 120?
(2a + 10)(2a - 12)
Factor 4a2 15a 9?
Assuming the missing signs are pluses, that factors to (4a + 3)(a + 3)

How do you simplify an expression in the format of 4a2 plus 4ab - y2 plus b2?
4a2 + 4ab - y2 + b2 You cannot simplify this expression because it does not contain like terms, but you can factor it such as: 4a2 + 4ab - y2 + b2 = (4a2 + 4ab + b2) - y2 = (2a + b)2 - y2 = [(2a + b) - y][(2a + b) + y]
How do you factor 8xA cubed plus C cubed?
