Answer:
radioactive decay
Explanation:
i just took the guiz and got it right
It depends if you are taking the class in high school or college. For college doing the experiments is fun but the calculations is not. Also if you are taking it, bring friends.
No. The speed of light does change. You mean speed of light in a vacuum. Measuring that value is elementary, in a 2-way measurement, as you show.
Answer:
V = 36.7L of 
Explanation:
1. Write the chemical reaction for the decomposition of sodium azide:
2. Find the number of moles of produced by the decomposition of 71.4g of 
:
3. Use the ideal gas equation to find the Volume of occupied by 1.65 moles of , at the temperature and pressure given by the problem:
Solving for V:
Converting the temperature from ◦C to K:
25◦C+273.15=298.15K
Replacing values:
V=36.7L of
The phosphate group contribute the following functional features to the structure of phospholipids:
1. Negative charge to interact with water.
2. Place to attach another small molecule.
The phosphate group is made up of four atoms of oxygen which are attached to one atom of phosphorus. This molecule has a net negative charge of -3. In the phospholipid molecule, the phosphate enhanced the polarity of the phospholipid head by mean of its negative charge which react with water. Phosphate group also provide a point where other small molecules such as alcohol, serine, etc can be attached.
