Carbon dioxide is only slightly soluble in water. One liter of water dissolves about 1.4 gm of the gas at 25 degree Celsius. Chlorine and hydrogen sulphide are much more soluble in water. A solution of CO2 in water is called carbonic acid (H20 + CO2= H2CO3).
Answer:
It is nucleus.
Explanation:
As you see in pic in center you see protons and neutrons. And electrons are surrounding them.
The mass of proton and neutron us close together but electron has the less mass.
Answer:
The average rate of the reaction in terms of disappearance of A is 0.0004 M/s.
Explanation:
Average rate of the reaction is defined as ratio of change in concentration of reactant with respect to given interval of time.
![R_{avg}=-\frac{[A]_2-[A]_1}{t_2-t_1}](https://tex.z-dn.net/?f=R_%7Bavg%7D%3D-%5Cfrac%7B%5BA%5D_2-%5BA%5D_1%7D%7Bt_2-t_1%7D)
Where :
= initial concentration of reactant at 
.
= Final concentration of reactant at 
.
2A+3B → 3C+2D
![R_{avg}=-\frac{1}{2}\frac{[A]_2-[A]_1}{t_2-t_1}](https://tex.z-dn.net/?f=R_%7Bavg%7D%3D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5BA%5D_2-%5BA%5D_1%7D%7Bt_2-t_1%7D)
The concentration of A at (
) = 
The concentration of A at (
) = 
The average rate of reaction in terms of the disappearance of reactant A in an interval of 0 seconds to 20 seconds is :
The average rate of the reaction in terms of disappearance of A is 0.0004 M/s.
Answer: The term covalent refers to a type of bonding in which pairs of valence electrons are shared by two atoms. Covalent compounds are those that exhibit covalent bonding. Molecular compounds are a type of covalent compound.
