Answer:
The two complex numbers are 
Explanation:
We have to form two complex numbers of the form
such that and d are irrational numbers and b and c are rational numbers.
We know that 
are irrational numbers.
5 and 6 are rational numbers.
We put
Thus, the two complex numbers are:
<h3>The average atomic mass of Iodine : 126.86 amu</h3><h3>Further explanation</h3>
Given
80% 127I, 17% 126I, and 3% 128I.
Required
The average atomic mass
Solution
The elements in nature have several types of isotopes
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% + ... mass isotope n.%
Atomic mass of Iodine = 0.8 x 127 + 0.17 x 126 + 0.03 x 128
Atomic mass of Iodine = 101.6 + 21.42 + 3.84
Atomic mass of Iodine = 126.86 amu
Answer - A substance is matter that has a uniform and definite composition. All samples of substances, sometimes called pure substances, have identical properties.
Answer:
As the electrons flow through the wire, <em>electric current </em>is generated around the wire.
Explanation:
The rate of flow of charged particles in a given time is termed as the flow of current. Mostly the charge carriers are termed as electrons in a conductor. So the flow of electrons or movement of charged particles in a given time is the generation of electric current in that current. As the ratio of charge to time at which the charge is moving from one point to another is termed as the current flow in that time.
Thus, in the present case of electrons flowing in that wire will lead to generating of electric current in the opposite direction around the wire.
Answer:
caused by the ability of electrons to flow from one half cell too the other
Explanation:
How is the potential voltage of a redox reaction?
The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. A redox reaction occurs when a certain substance is oxidized, while another is reduced.
