Explanation:
I did the test and got it right
Thus the answer is b.
Explanation:
In order to find whether it will sink or float in water we must first find the density of the object
The density of a substance can be found by using the formula
From the question
mass = 18 g
volume = 9 cm³
So we have
We have the density as 2.0 g/cm³
The object will sink in water since it's density is greater than that of water which is 1.0 g/cm³
Hope this helps you
Answer:
A salt bridge refers to a device used to form an electrochemical cell by providing a means to support the free flow of ions between the oxidation and reduction half-cell components. A salt bridge facilitates corrosion because corrosive reactions typically occur in the presence of electrochemical cells.
Explanation:
Silicon is a popular semi-conductor. The process of doping either creates an excess or lack of electrons. In the case of silicon, the dopant is arsenic which has greater valence electron than silicon. Arsenic then donates an electron resulting to an excess of electrons. A new type or better type of semi-conductor is created. Silicon conduct greater electricity.
The best answer is the last option.
