<em>The Molecular Mass for Phosphorus is 31 grames / mole.
So, 31g. P.....................1 mole
2.3g. P ..........................x mole
</em>

According to Newton's first law of motion, it takes an unbalanced force to move an object at rest.
I hope this helps :)
Answer:
B: increase.
Explanation:
When we are considering two gases A and B in a container at room temperature .
We have to find the change on rate of reaction when the number of molecules of gases A is doubled
Let [A]=a and [B]=b
A+B product
Rate of reaction
We know that concentration is increases with increase in number of moles
When the number of molecules of gases A is doubled then concentration of gases A increases.
Therefore ,[A]=2a
Rate of reaction
Hence, the rate of reaction is 2 times the initial rate of reaction.Therefore, the rate of reaction will increase when the number of molecules of gases A is doubled.
Answer: B: increase.
Answer:
Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. It can also call for a new theory, either by showing that an accepted theory is incorrect, or by exhibiting a new phenomenon that is in need of explanation.

Explanation:
∆H is known as the change in enthalpy. When the change in enthalpy is negative, it simply means that heat is given out during the reaction. Therefore, we refer to the reaction as an exothermic reaction.
Similarly, ∆G is known as change in free energy. When the change in free energy is negative, it implies that the reaction is spontaneous as written. This is called an exergonic reaction.
