Answer: Scientific notation-
Explanation: I got this by moving the decimal, so that there is one non-zero digit to the left of that decimal point. Tip- The number of decimal places you move will be the exponent on the 10.
Moved right- Negative
Moved left- Positive
The formula of De Broglie is the following:
Remember that the mass of an electron is 9.11 x 10 ^(-31) kg, so replacing in the formula, we're going to obtain:
The answer is that the wavelength of an electron traveling at 1.48 x 10^(5) m/s is 4.91 x 10^(-9) m.
Answer:
pH= 1.70
Explanation:
I 4.988 0 0
C -x +x +x
E 4.988 -x x x
8.0 x 10^-5 = X^2/ 4.988 - x
(since the X value is so small, round 4.988-x to 4.988 because X is close to zero)
8.0 x 10^-5 = x^2/4.988
x4.988 x4.988
4.0 x 10^-4 = x^2
x = .0199
pH=-log[.0199] = 1.70
Dependent variables have to be in the experiment for it to work
independent variables do not.
