William asks…How many liters of a 10% alcohol solution must be mixed with 50 liters of a 80% solution to get a 30%?How many liters of a 10% alcohol solution must be mixed with 50 liters of a 80% solution to get a 30% solution?Nancy answers:Let the no. Of litres required be x.
(10/100) * x + (80/100) * 50 = (30/100) * (x + 50)
10x + 4000 = 30 (x + 50)

Surfing For How Many Liters Of A 30 Alcohol Solution?
Steven asks…How many liters of 30% alcohol solution a,?Please help. How many liters of 30% alcohol solution a, is mixed with 70% alcohol solution b to produce 20 liter 40% alcohol solution?Nancy answers:Lets rename Solution A as (x) and Solution B as (20-x). You can find the value of (x) itself and then subtract that from the total of 20 liters to find Solution B which we renamed as (20-x)
so 30% of (x) plus 70% of (20-x) = 40% of 20 liters.
Turn % into decimal and rewrite:
.30(x) +
so 30% of (x) plus 70% of (20-x) = 40% of 20 liters.
Turn % into decimal and rewrite:
.30(x) +
Surfing For How Many Liters Of A 90 Acid Solution?
James asks…how many liters of a 90% acid solution must be added to 6 liters of a 15% acid solution to obtain a 40% acid?solution?Nancy answers:0.90x + 0.15(6)
------------------------ = 0.40
x + 6
0.90x + 0.90
--------------------- = 0.40
x + 6
0.40(x + 6) = 0.90x + 0.90
0.40x + 2.40 = 0.90x + 0.90
-0.50x = -1.50
x = 3
The answer is 3 liters.

Surfing For Agcl Is It Aqueous?
Jenny asks…the weight of pure, dry AgCl obtained is?all of the chloride ion in 1.0 mol of MgCl2 is precipitated from aqueous solution as AgCl. So.. the weight of pure dry AgCl is?
please explain so i can understand how to do it. thanks
don't give me the answer. thank you.Nancy answers:First balanced equation
MgCl2 + 2Ag+ = 2AgCl + Mg2+
So one mole of MgCl2 produces 2 moles AgCl2
Mass of the AgCl = moles * MW
= 2 *(108+35.5)
= 287g
= 290g using correct number of significant

Jenny asks…Finding mass of the AgCl precipitate?When silver nitrate is added to an aqueous solution of magnesium chloride, a precipitation reaction occurs that produces silver chloride and magnesium nitrate. When enough AgNO3 is added so that 24.5 MgCl2 react, what mass of the AgCl precipitate should form?Nancy answers:I presume you mean 24.5g MgCl2 not 24.5kg MgCl2?
Mass must have a unit.
As always, start with balanced equation
MgCl2 + 2AgNO3 ---> 2AgCl + Mg(NO3)2

Mandy asks…kinematics please help?A driver takes 0.2s to apply brakes after he sees a need for it.This is called reaction time of the driver.If he is driving a car at a speed of 54km/hr and the brakes cause a deceleration of 6 m/s^2,
find the distance travelled by the car after he sees the need to put the brakes on.Nancy answers:54km/hour = 15m/s.
Distance traveled in 0.2 s = 0.2 x15 m =3m.
Distance traveled with a deceleration of 6m/s^2 is found
using the relation V^2 = U^2 + 2 a

Also, find the speed of the car in Kilometers per hour.Nancy answers:X² + 9x - 90 = 0.
This factors to (x + 15)(x - 6) = 0, so
x = -15 or x = 6.
Discard the negative possibility, since he's not driving backward; therefore x = 6.
Check: 6² + 9(6)
