Using a scientific explanation, describe if the weight of a mixture will change after going through a chemical reaction. State your claim and provide specific evidence . And reasoning for your answer.

Answers

Answer 1

Answer:

See explanation

Explanation:

In order to answer this question, we have to look at the principle of conservation of mass. This principle states mass is neither created nor destroyed in a chemical reaction.

Hence, in a chemical system undergoing a reaction, the total number of atoms present in the system remain the same before and after the reaction. This also implies that the weight of the system does not change.

Thus, the weight of a chemical system does not change after a chemical reaction.

"A Christmas Carol", list some gothic traits you noticed in this story. What makes this story fit into the Gothic genre?

Answers

Answer and Explanation:

The melodrama present in "A Christmas Carol" is the main element that makes this work fit into the Gothic genre. That's because Scrooge's story is full of melodramas, from his youth to his old age. In addition, "A Christmas Carol" presents a sinister, mysterious setting, with night scenes and supernatural beings, which are also common elements of the Gothic genre. We must not forget that this book presents concepts and ideas about death and spiritual life, which also allow it to be characterized as a Gothic book.

They were replaced by alarms are there no Knocker-ups today. Thus, option (d) is correct.

What is Knocker-ups?

The knocker-uppers were given one shilling each client per week. The cost of waking up was determined by the time of day and the distance between the clients' homes. Early hours, such as 4 a.m., were more expensive than awake hours around 5 and 6 a.m.

What does the interaction between becky and isabel tell us about isabel what tone is created here in the book chains

Answers

Answer: Their interaction shows that Isabel still believes in finding people with good hearts, despite being a slave and having had several mean "owners". A reflective tone is created in the book.

Explanation: Isabel is forced to labor as a slave along with her little sister. Although Isabel passes through many ruthless owners, the fact that she has a good relationship with Becky, who is Madam Lockton's' housekeeper, proves that despite having had experiences of mistreatment with people in a higher position than her, she still believes in kind people. The book creates a reflective tone, since she's incredibly observant and brave, and the difficult situations she's put in made her a mature person at a very young age.
