In an atom, the protons, which have a positive charge, and the neutrons, which have a neutral charge, are located in the nucleus. The electrons, which have a negative charge, orbit the nucleus of the atom.
Answer:
The number of chlorine atoms present in
units of gold III chloride is
Explanation:
Formula of Gold (III) chloride: 
<em>Avogadro Number</em> : Number of particles present in <u>one mole</u><u> </u>of a substance.
Using,


= 1 mole(0.9999 , nearly equal to 1 )
The given Gold III chloride sample is 1 mole in amount.
= 1 mole of 
In this Sample,
1 mole of
will give = 3 mole of Chlorine atoms
1 mole of Cl contain =
3 mole of Cl contain = 
3 mole of Cl contain =
So,
The number of chlorine atoms present in
units of gold III chloride is
Answer:
Half-life = 1.21x10⁻⁴ years⁻¹
Explanation:
The kinetics decay of ¹⁴C follows the first order reaction. That means half-life of ¹⁴C is defined as:
Half-life = ln 2 / K
<em>Where K is decay constant.</em>
<em />
As decay constant of ¹⁴C is 5730 years, half-life is:
Half-life = ln 2 / 5730 years
<em>Half-life = 1.21x10⁻⁴ years⁻¹</em>
<em />
Answer:
Calcium chloride is the ionic compound of C and Cl
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl₂. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
