C. The action/reaction law states that a force is equal in both directions.
Hey there!
Ba(NO₃)₂
Ba: 1 x 137.327 = 137.327
N: 2 x 14.007 = 28.014
O: 6 x 16 = 96
-----------------------------------
261.341 g/mol
The molar mass of Ba(NO₃)₂ is 261.341 g/mol.
Hope this helps!
Answer:
ANIMAL CELL
Animal cells are generally small in size.
They don't have a cell wall
Except the protozoan Euglena, no animal cell possesses plastids.
Vacuoles in animal cells are many, small and temporary.
Animal cells have a single highly complex and prominent Golgi apparatus.
Animal cells have centrosome and centrioles.
PLANT CELL
Plant cells are larger than animal cells.
The plasma membrane of plant cells is surrounded by a rigid cell wall of cellulose.
They have Plastids
Most mature plant cells have a permanent and large central sap vacuole.
Plant cells have many simpler units of Golgi apparatus, called dictyosomes.
Plant cells lack centrosome and centrioles.
Hope this helps!
<u>Answer:</u> The half life of the reaction is 593.8 seconds
<u>Explanation:</u>
We are given:
Rate constant = 
The formula for determining the unit of 'k' is:

where, n = order of reaction
The unit of concentration is, M or mole/L
The unit of time is, second or 's'
Evaluating the value of 'n' from above equation:

The reaction is zero order reaction.
The equation used to calculate half life for zero order kinetics:
![t_{1/2}=\frac{[A_o]}{2k}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B%5BA_o%5D%7D%7B2k%7D)
where,
k = Rate constant = 
= initial concentration = 1.90 mol/L
Putting values in above equation, we get:

Hence, the half life of the reaction is 593.8 seconds
