<span>On a molar a basis, the most effective bleaching agent kbro3 has more oxygen, but due to the bromine, it would make things look yellowish. The bromine would counteracts the bleaching effect. As we all know, bleach is naocl or hypochlorite</span>

Answer:
Decreasing temperature.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- The choices here:
1) Decreasing concentration of SO₂,
The concentration of SO₂ decreases, so the reaction will be shifted to the left direction to suppress the decrease in SO₂ concentration.
2) Decreasing temperature,
ΔH= – 98.8 kJ/mol, the negative sign means that the reaction is exothermic and release the heat.
If the temperature decreased, this means that the products decrease, so the reaction will shift to the right to suppress the decrease in temperature.
<em>It is the right choice.</em>
3) Increasing concentration of SO₃:
Increasing concentration of SO₃ will shift the reaction to the left to suppress the effect of increasing the concentration of SO₃.
4) Increasing volume:
Increasing the volume will decrease the pressure.
Decreasing the pressure will shift the reaction of gases to the side of higher no. of moles (left side).
- <em>So, the right choice is: Decreasing temperature.</em>

They found that difference occurs in the speed of both sound and charges occur due to the difference in the type of medium.
Sound and charges needs specific medium for faster movement i.e. sound moves faster in solid as compared to liquid and gas whereas charges moves faster and easily in gold due to lower resistance which is followed by copper. Sound can move from solid, liquid and gases whereas charges move only in solid metal in which free electrons are present. The speed of sound and flow of current are affected due to difference in the arrangement of atoms in solid, liquid and gas.

Answer:
PBr3 - Molecule , Polar
N2H2 - Molecule , (Polar in E- form and Non- polar in Z form)
C2H2 - Molecule , Non- Polar
N2 - Molecule , Polar
NCl3 - Molecule , Polar
SiF4 - Molecule , Non- Polar
NH3 - Molecule , Polar
F - Not- Molecule (atom)
H2 - Molecule and Non- Polar
Explanation:
Molecule : these are group of two or more atoms joined by strong force of attraction.
H2 is non- polar because it is homoatomic molecule.(made up of same element)
N2 is non- polar because it is homoatomic molecule.
