Answer:
765.95 grams.
Explanation:
2 moles of KClO3 produce 3 moles of oxygen.
Using molar masses:
2 * 122.545 g of KCLO3 produces 47.997 grams of oxygen.
47.997 g O2 is produced from 245.09 g KCLO3
150 g .......................................... 150 * 245.09 / 47.997
= 765.95 grams.
As of right now, the current atomic theory states that an electron's position cannot be determined but the probable position of it can be determined with the probability field. The probability cloud should be the answer. I am not sure what the three main parts is referring to<span />
Answer : The correct option is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Explanation :
Acceleration : It is defined as the change in velocity divided by the time.
The formula of Acceleration is,
So, we can calculate the acceleration only for 2nd option which is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
In this option, velocities and time are given.
In all the other options, the velocity and time are not given. So, we can not calculate the acceleration.
Hence, the correct option is a car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
