Answer:
A ability to decompose
B reactivity
Explanation:
Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water by an electric current.
The ability to decompose and reactivity are chemical properties of a substance.
- Physical properties tells us everything about what a substance is when no change is occurring to its constituents.
- Examples are state of matter, color, odor, taste, texture, hardness e.t.c
Answer:
Distance: 16m Displacement: 8m North
Explanation:
Total distance is the total amount traveled, regardless of direction. So, you would just add 12 and 4 to get a total distance of 16m. Displacement is the distance/direction from the start to the end point, regardless of which way you got there. So, to find displacement, you just subtract:
12m North - 4m South = 8m North

Answer:
Brown color of the solution decreases
Explanation:
is brown in color whereas is colorless.
Equilibrium reaction between and is as follows:
As per the Le Chatelier's principle, if pressure of a equilibrium is increased, the equilibrium will shift in the direction having fewer no. of moles of gases.
In the given equilibrium, side has more no. of moles. So on increasing pressure, equilibrium will shift towards the side of or more formation of will take place.
Therefore, more will decompose that will decrease the brown color of the solution as is colorless.
