How can prepare 10 percent ammonia solution from 26 percent ammonia solution?
Check what it is dissolved in first and use the same solvent for dilution. If you want to make a litre of 10% for instance, You want to dilute it 10 in 26 parts or 5 in 13. So 1 litre /13*5 is 384.6ml of 26% ammonia, and dilute to 1 litre with solvent
What is the oxidation number of C2H4O?
The oxidation number of carbon in C2H4O is +2, as each hydrogen has an oxidation number of +1 and each oxygen has an oxidation number of -2. By setting up the equation 2x + 4(+1) + 1(-2) = 0, you can solve for x to find the oxidation number of carbon.
A solution is tested and found to have a pH of 1 the solution is?
The solution is acidic. A pH of 1 indicates a high concentration of H+ ions in the solution, making it strongly acidic.
How do you prepare 1 N to 0.1N NaOH solution?
To prepare 0.1N NaOH solution from a 1N NaOH solution, you can dilute 1 part of the 1N solution with 9 parts of water (since 1/10 = 0.1). Measure 1 volume of the 1N NaOH solution and add 9 volumes of water to it, then mix well to get your 0.1N NaOH solution.
How much more basic is a solution with a pH of 13 than one with a pH of 10?
Since pH is a logarithmic scale, each increase (or decrease) by 1 means 10 times, so the change of pH in a solution from 10 to 11 would be 10 times, 11 to 12 would be 10 times, and 12 to 13 would be 10 times, and (10)(10)(10) is 1000, so a solution with pH 13 is 1000 times more basic then a solution with pH 10
1- Which of the ordered pairs is a solution of 2x plus 3y equals 13?
2x plus 3y
Is (1 1) a solution to 3y 2x 1?
Yes if you mean (1, 3) and 3y = 2x+1
How do you factor 12x2-27y2?
3(2x + 3y)(2x - 3y)
How do you solve 2x plus 1 equals 3y and 4 equals 3y-10 by elimination?
1) 2x + 1 = 3y 2) 4 = 3y - 10 this can be re-written as 3y = 4 + 10 Therefore 2x + 1 = 4 + 10 2x = 13 x = 6.5 Sustitute x = 6.5 in equation 1) above 2x + 1 = 3y 2 (6.5) + 1 = 3y therefore 3y = 13 +1 3y = 14 y = 14/3 Now substitute y = 14/3 in equation 2) above and watch what happens! 4 = 3(14/3) -10 4 = 4 Therefore the answer is correct!
What the solution of 2x plus 5y equals 16 and 2x plus 3y equals 14?
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
Which ordered pair could be a solution to this inequality 3y -1 - 2x?
To determine if an ordered pair ((x, y)) is a solution to the inequality (3y - 1 - 2x \geq 0), we can rearrange it to (3y \geq 2x + 1). For example, if we take the ordered pair ((1, 1)), we substitute (x = 1) and (y = 1): (3(1) \geq 2(1) + 1), which simplifies to (3 \geq 3). Since this is true, ((1, 1)) is a valid solution to the inequality.
How do you do this problem 2x plus 3y equals 1?
2x + 3y = 1 y = 1/3 - 2x/3
How to graph -2x plus 3y equals 1?

What is the solution to this system of equations 6x-3y -33 2x y -1 using substituition?
If you mean: 6x-3y = -33 and 2x+y = -1 Then solving the simultaneous equations by substitution: x = -3 and y = 5
If 2x-3y equals -1 and 3x plus 2y equals 31 find the values of x and y?
2x - 3y = -1 3x + 2y = 31 eqn(1) * 2: 4x - 6y = -2 eqn(2) * 3: 9x + 6y = 93 Add the two: 13x = 91 Divide both sides by 13: x = 7 Substitute this value of x into eqn(1): 14 - 3y = -1 Add 3y to bot sides: 14 = -1 + 3y Add 1 to both sides: 15 = 3y Divide both sides by 3: 5 = y So the solution is x = 7, y = 5
