Using your senses like nose, mouse, hand, ears and others to gather information is called<u> observation.</u> You can get information by feeling, tasting, smelling,hearing and so on.
Answer:
160 gm
Explanation:
Five times as much water means you can dissolve 5 times as much potassium nitrate 5 x 32 = 160 gm <u> <===== this seems unlikely though as I doubt 32 g of potassium nitrate will dissolve in only 1 cm^3 of water 1 cm^3 of water is only 1 gm of water </u>
Answer:
The reaction is not at equilibrium and reaction must run in forward direction.
Explanation:
At the given interval, concentration of NO = 
Concentration of 
= 
Concentration of NOBr = 
Reaction quotient,
, for this reaction = ![\frac{[NOBr]^{2}}{[NO]^{2}[Br_{2}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNOBr%5D%5E%7B2%7D%7D%7B%5BNO%5D%5E%7B2%7D%5BBr_%7B2%7D%5D%7D)
species inside third bracket represents concentrations at the given interval.
So, 
So, the reaction is not at equilibrium.
As 
therefore reaction must run in forward direction to increase and make it equal to 
.
Answer:
A scale, or a weight. Both of which are more scientifically referred to as a balance.
Answer:
The answer should be 1000 kg / m3
