(sec/2.5C)x(1/35.0min)x(min/60sec)x(96,500C/mole e-)x(2 mol e-/mol M)x(3.06g M)=112.4g/mol
The element with that molar mass is Cadmium, Cd.

How can you identify the deposited materials that were left there directly by a glacial ice deposits?
* Heterogeneous. (All different sizes). * Jagged fragments. * Angular rock. * Unsorted. * Unstratified.
What other means of qualitative analysis are to identify metals?
calculate the density of the element because each element has a different density
What are the usefulness of density in identification of unknown substance?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What does the solubility of a substance tell you?
because it is a characteristic property of matter
How do you implement ALARA in a Nuclear Industry?
The same way you implement ALARA in every industry: Identify the risks, gauge their relative danger, figure out how much it would cost to reduce the risk, calculate if it is fiscally efficient to perform the reduction.
Identify the antecedent of the pronoun it. Pat gave the money to Sam who deposited it in the bank?
The antecedent of the pronoun 'it' is the noun money.
What term is used to identify a windblown sediment of silt and clay?

What are some signs of the mental health disorder that you can identify?
Getting constant raging boners
What are some properties used to identify kinds of matter?
Some properties are they are in constant motion.
What is the compares in constant and variable rate of change?
Tell whether the equation -4x+ 2y = -2 represents a direct variation. If so, identify the constant of variation.
How can you identify the deposited materials that were left there directly by a glacial ice deposits?

How do i identify and calculate the area and perimeter for quadrilaterals?
P= Add all sides A= LxW
How do you identify balanced forces?
The object the forces are acting on will not move, or will be moving at a constant speed (e.g. not accelerating). This is called being in 'equilibrium'.
How can you identify a unit rate or constant of proportionality a table?
Divide an entry for one variable in the table by the corresponding entry for the other variable.
What symbol is used to specify calculation?
Use the equal sign (=) to identify cell entries that should attempt to calculate a value.
What other means of qualitative analysis are to identify metals?
calculate the density of the element because each element has a different density
