A: H2 + Cl2 -> 2HCl represented by equation
Answer: True
Explanation: Every atom of the same element has the same atomic number of number of protons in its core. This is why chemists say that an atom is defined by its atomic number of the number of protons.
Unlike neutrons and electrons, you can't change protons. You can change the number of neutrons and it will still be the same element, but one is going to be a little bit heavier or a little bit lighter than another.
In addition, you can change electrons which creates
ions or charged atoms.
However, you can't change the protons.
For example, hydrogen has 1 proton in its nucleus no matter what and helium has 2 protons in its nucleus no matter what and so on.
Explanation:
The given chemical equation is:
The rate of the reaction is 0.0352 M/s.
During the course of the reaction, the rate of reactants decreases, and the rate of products increases.
The rate of disappearance of B is shown below:
So, rate of change of B is :
Option C.
None. AlCl3 is aqueous, and AgBr forms a precipitate, although AgBr3 does not exist
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
