Molarity of hydrogen solution equals 2.3 X 10^-4
-log(2.3 X 10^-4)
= 3.6 pH
to get the answer of this is to change the whole thing to algebra that is Let put an X as unknown squared number X * X + 23 =104 subtract 23 from both sides X * X + 23 - 23 = 104 - 23 X * X = 81 Now find the square root of 81. the square root of 81 is 9. check: 9 * 9 + 23 = 104
A two-step equation with a variable that equals 23 could be (2x + 5 = 23). To solve for (x), first subtract 5 from both sides to get (2x = 18), and then divide by 2 to find (x = 9). Thus, the solution satisfies the original equation.
(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)
Expressing 104 in terms of its prime factors we have, 104 = 2 x 2 x 2 x 13. Puttting these factors into exponential form : 104 = 23 x 131. However, by common usage an exponent of 1 is rarely shown and the normal expression would be, 104 = 23 x 13.
Another Answer:The length of the rectangle is 29 cm because 2*(29+23) = 104 cm which is the perimeter
-23+7=-16
23 x 13 = 104

It's a simple linear equation in 'h' .Its solution is [ h = 4 ].
to get the answer of this is to change the whole thing to algebra that is Let put an X as unknown squared number X * X + 23 =104 subtract 23 from both sides X * X + 23 - 23 = 104 - 23 X * X = 81 Now find the square root of 81. the square root of 81 is 9. check: 9 * 9 + 23 = 104
3x + 8 = 23 Subtract 8 from both sides: 3x = 15 Divide both sides by 3: x = 5
The pH scale measures the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, making the solution more acidic. Conversely, a higher pH value indicates a lower concentration of hydrogen ions, making the solution more basic.
23-9 equals = 14

1x23 equals 23 duh
23 - x equals 142 = -119
