Answer:
Static electricity is transferred during charging by conduction when electrons from a charged from one object to another object by direct contact. For example, on a carpet, charges are transferred from a person's feet to the rest of his/her body.
Answer:
0.30 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 25.0 mL
M₂ = 0.117 M
V₂ = 65.5 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
Putting the respective values -
M₁ * 25.0mL = 0.117 M * 65.5 mL
M₁ = 0.30 M
The type of reaction that occurs without the addition of heat is called spontaneous reaction. That is option D.
<h3>What is spontaneous reaction?</h3>
Spontaneous reaction is defined as the reaction where by new substances are formed naturally without the addition of extra energy in the form of heat.
Therefore, the type of reaction that occurs without the addition of heat is called spontaneous reaction

D is the correct answer for your question. Maybe I am not sure.
Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.
