Answer:
option c
Explanation:
as catalyst increases the reaction while activation energy is inversely proportional to rate of reaction, so option c is correct

Hello!
In this case, since the presence of silver ions is in AgNO3 only, we can compute their moles by using the volume and concentration of the corresponding salt:
![n_{Ag^+}=2.00L*2.00\frac{mol}{L}=4molAg^+](https://tex.z-dn.net/?f=n_%7BAg%5E%2B%7D%3D2.00L%2A2.00%5Cfrac%7Bmol%7D%7BL%7D%3D4molAg%5E%2B)
Next, since the total volume of solution C is 5.00 L, the required concentration of silver ions turn out:
![M=\frac{4.00mol}{5L} =0.8M](https://tex.z-dn.net/?f=M%3D%5Cfrac%7B4.00mol%7D%7B5L%7D%20%3D0.8M)
Best regards!
Answer:
Answer is Object 2 (which has a density of 1.9 g/cm³).
Explanation;
When object is floating, the weight of that object is less than the up thrust on it.
When an object fully submerged and floating, then the weight of that object is equal to the up thrust on it.
This is known as the Archemide's principle.
Both up thrust and weight depends on the density. Hence, if the density of the solution is high, then the up thrust also high. If the density high, the the weight of the object also high.
Hence, to sink the object in water, that object should be denser than water. Hence, answer is object 3 which has a higher density than water.
