Percent yield represents to what extent the reaction runs to completion. In this, the theoretical yield is 50 grams (100% completion).
To calculate percent yield, divide the actual by the theoretical. In doing so, the percent yield is 88% (44/50).
A phase change from Gas to liquid means that it was cold outside and so the molecules went from being very free moving to forming bonds with one another due to the cold.
An original sample of K-40 has a mass of 25.00 grams.
After 3.9 m 109 years, 3.125 grams of the original sample remains unchanged.
What is the half-life of K-40?
First step is to determine the remaining decimal amount.
3.125 grams /25.00 grams = 0.125
Second step is to determine the number of half lives.
(1/2)^n = 0.125
N log (1/2) = log 0.125
N = 3 years
Answer:
An electron charge has maximum kinetic energy (ie free movement) at infinity distance from a nucleus. It has maximum potential (binding) energy when it is 'touching' a positive charge in the nucleus.
Answer:
The correct answer is - cellular respiration is when <u><em>chemical</em></u> energy from sugar/glucose is converted to cellular <u><em>energy in the form of ATP</em></u><em><u>.</u></em>
Explanation:
Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.
In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.
