Answer:
A
Explanation:
This popular experiment enabled us to know the charge of an electron. It was performed by Robert Millikan and Harvey Fletcher and have the process and procedure to measure the elementary electronic charge. In fact, Robert Millikan was awarded the Nobel prize in physics in the year 1923 for how efforts.
They were able to determine the charge by repeating the experiment for several droplets and later proposed that the charges were integer multiples of a particular base value.
Among many factors, the concentration of reactant is also responsible for effecting the rate of reaction. And it is found that the rate of reaction is directly proportional to the rate of reaction.
Explanation:
Higher concentration means greater number of reactants in the system. Greater the number greater will be the probability of reactants to colloid. And according to collision theory reactants must colloid with optimum kinetic energy and orientation. So, in higher concentrated system the rate of collisions increases with increasing the rate of reaction.
Result:
Option <span>A is correct answer. (The increased concentration increases the number of collisions between molecules.)</span>
B. stimulant drug.
The Department of health states that it is a stimulant.
Answer: You will notice that water droplets form on the outside of the bottle. These droplets are water vapor from the atmosphere condensing on the surface of the bottle. They do this because the surrounding air cools when it touches the bottle. Clouds form the same way. Water vapor in the atmosphere cools and condenses on particles in the air, creating a cloud.

Answer:
The answer to your question is below
Explanation:
Data
Aqueous acetic acid
Aqueous barium hydroxide
Formula
Acetic acid CH₃CH₂COOH
Barium hydroxide Ba(OH)₂
Neutralization reaction
CH₃CH₂COOH + Ba(OH)₂ ⇒ Ba( CH₃CH₂COO)₂ + H₂O
Barium acetate + H₂O
Barium acetate = Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
