according to the collision theory, for a reaction to be successful, it must have correct orientation of the atoms of the reactan
DerKrebs [107]
The collision must have sufficient energy as well.  If sufficient energy is not present the activation energy will not be over come and the bonds in the reactants will not be broken.

I hope this helps.  Let me know if anything is unclear.

What is the concentration of a solution in which 10.0 g of AgNO, is dissolved in 450 mL of solution?
Rufina [12.5K]

Answer:

M=0.15

Explanation:

138 g AgNO -> 1 mol AgNO

10 g AgNO   -> x

x= (10 g AgNO * 1 mol AgNO)/138 g        x=0.07 mol AgNO

450 mL=0.45 L

M= mol solute/L solution

M= 0.07 mol AgNO/0.45L

M=0.15

Predict what will be observed in each experiment below. experiment predicted observation.
irga5000 [103]

Answer:

The correct answer is -

1.  a) The bubbles will shrink, some may vanish.

2. a) Can A will make a louder and stronger fizz than can B.

Explanation:

In the first question, it is given that the bottle is not opened and therefore, squeezing the bottle filled with a carbonated drink will increase the pressure on the carbonated liquid which forces the bubbles to dissolve or displace or vanish as it moves to empty space.

Thus, the correct answer would be - The bubbles will shrink, some may vanish

In the second question, there are two different conditions for two different unopened cans of carbonated water that are different temperatures one at the garage with higher temperature and one in the fridge at low temperature. As it is known that higher the temperature less will be solubility of gas in liquid so gas in can A will be less soluble which means it has more gas and it will make louder and stronger fizz than B which was stored at low temperature.

thus, the correct answer would be - Can A will make a louder and stronger fizz than can B.
