Answer:
Explanation:
Hello,
In this case, by considering the mathematical definition of by mass percentage of a solute as shown below:
We are able to compute the mass of the solute in a 20% solution having 500 g of solution as follows:
Best regards.
Answer:
Bottle is sitting on the shelf for 15 days.
Explanation:
Given data:
Co-60 half life = 5 days
Total amount = 30.0 g
Amount left = 3.75 g
Time taken = ?
Solution:
AT time zero = 30 g
AT first half life= 30g /2 = 15 g
At 2nd half life = 15 g/ 2 = 7.5 g
At 3rd half life = 7.5 g/2 = 3.75 g
Now we will calculate the sitting time of bottle.
Half life = Time taken / number of half lives
3× 5 days = time taken
Time taken = 15 days
Bottle is sitting on the shelf for 15 days.
Answer:
- CH3CH2CH2CH2CHCH2OH Hexanol
Explanation:
Hydroboration reaction of Hexene yields Hexanol
<span>It changes with new evidence.
The example shows that science changes with new evidence. Science can not change with common beliefs because first of all beliefs should be proved and become evidence. Second, science is not fixed because of the scientific method and experimentation, which is a phase of the scientific method.

The cylinder's acceleration is
θ
<h3>
How do you determine a cylinder's acceleration?</h3>
The cylinder's complete radius, 
, from the center marks the contact point, therefore the torque created by friction is given by 
, where is the rotating acceleration. This rotational acceleration's corresponding linear acceleration, 
, is equal to . The cylinder, which has its mass concentrated in its center, triumphs in the competition, followed by the disc and the hoop, with their respective final velocities being roughly 
. We can also see that our findings are unaffected by the cylinders' masses.
