Answer:
The pressure is 
Explanation:
From the question we are told that
The volume of Ne is 
The volume of CO is 
The pressure of 
is 
The pressure of CO is 
The number of moles of Ne present is evaluated using the ideal gas equation as
=> 
The number of moles of CO present is evaluated using the ideal gas equation as
=> 
The total number of moles of gas present is evaluated as
The total volume of gas present when valve is opened is mathematically represented as
=> 
So
From the ideal gas equation the final pressure inside the system is mathematically represented as
=> ![P_f = \frac{[\frac{4.185}{RT} ] * RT }{ 4.50}](https://tex.z-dn.net/?f=P_f%20%20%3D%20%20%5Cfrac%7B%5B%5Cfrac%7B4.185%7D%7BRT%7D%20%5D%20%20%2A%20%20RT%20%7D%7B%204.50%7D)
=>

Dr. Khan works for the marketing department of a company that manufactures mechanical toy dogs. Dr. Khan has been asked to assess the effectiveness of a new advertising campaign that is designed to be most persuasive to people with a certain personality profile. She brought four groups of participants to the lab to watch the video advertisements and to measure the likelihood that they would purchase the toy, both before and after watching the ad. The results of Dr. Khan’s study are presented below.
Part A
Explain how each of the following concepts applies to Dr. Khan’s research.
Survey
Dependent variable
Big Five theory of personality
Part B
Explain the limitations of Dr. Khan’s study based on the research method used.
Explain what Dr. Khan’s research hypothesis most likely was.
Part C
Use the graph to answer the following questions.
How did the trait of agreeableness affect how people responded to the new ad campaign?
How did the trait of conscientiousness affect how people responded to the new ad campaign?
Answer:
The correct answer is C.) metallic bonds
Explanation:
Metallic bonds are formed between metal compounds and are very strong. These links are explained by the "sea model of electrons", where valence electrons are ceded by each metal atom, becoming positive ions forming a three-dimensional crystalline network. These electrons move forming a network ("sea") that allows the union of the positive ions formed.
<h3>Answer:</h3><h2>Chemical properties</h2><h3>Explanation:</h3>
By its very definition, a chemical property is one which is exhibited as a result of a chemical reaction. This may happen during or after the reaction. This is because in a chemical reaction there is a transformation in the physical composition of the components and this directly affects its chemical properties.
