Answer:
See the answer below
Explanation:
<u>A scientist B might want to replicate the experiment of another scientist A in order to assess the claims made by scientist A.</u> In other words, replication of the experiment of another scientist is done to see if a similar outcome would be arrived at or there would be variations. 
<em>The claims made by a scientist while reporting the outcome of a particular experiment must be reproducible by another scientist under similar conditions. Otherwise, the claims are said to be false.</em>
 
        
             
        
        
        
Answer:
F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)
Explanation:
Our reactants are:
F₂ → Fluorine gas, a dyatomic molecule
FeI₂ → Iron (II) iodine
Our products are:
I₂ → Iodine
FeF₂ → Iron (II) fluoride
Then, the reaction is:
F₂ (g) + FeI₂ (aq) →  FeF₂ (aq) +  I₂ (l)
We see it is completely balanced.
 
        
             
        
        
        
Gravity is the force of motion pulling down objects to the ground. If there was no gravity, everyone would walking as if they were on the moon. 
Mass is what gravity needs. If an object has a little amount of mass, gravity will be able to easily bring it to the ground. 
If an object has a very huge amount of mass, gravity will still be able to bring it to the ground but it will be hard. 
For example: An airplane has a HUGE amount of mass. Gravity pulls it down but the airplane needs to be steering up in order for it to be straight. Gravity is applied on the airplane when it is landing. 
BUT..... if a table is in the way of an object it depends if it will fall down to the ground or stay on the table. 
If an object has little mass and a table is in the way of gravity pulling it down to the ground, the object will stay on the table. Like a plate of food on a table. 
If an object has a very big amount of mass and a table is in the way of gravity pulling it to the ground, the object will break the object and make it's make to the ground. That is mostly why most of the time people have very strong tables/ anything to hold a heavy object.  
Another example is if you're lifting weights and you have little amount of mass, you're most likely to get the little sized weight. It depend on you mass. 
Here are some pictures I included here as well of Mass and gravity. 
Glad to help! :) :D 
 
        
        
        
<span>The answer is B.They cannot produce enough heat to keep their bodies warm.
In order to survive, the alligators rely on warm weather, and they are most active when the environment is 82-92 degrees Fahrenheit. They can survive below or above this temperature range but they may spend that time struggling to stay warm or stay cool.
