Metal X is more reactive than metal Y. Metal Y is more reactive than metal Z. Which statement is correct? (1 mark)

A) When metal X is placed in a solution of Y sulfate, there is no reaction.

B) When metal X is placed in a solution of Z sulfate, a reaction occurs.

C) When metal Y is placed in a solution of Z sulfate, there is no reaction.

D) When metal Z is placed in a solution of X sulfate, a reaction occurs.​

Answers

Answer 1

The correct answer is option B) ie When metal X is placed in a solution of Z sulfate, a reaction occurs.

The metals in the reactivity series are ordered in descending order of reactivity. The difference in stability between metals' electron configurations as atoms and as ions accounts for their reactivity. They will all react to produce positive ions because they are all metals.In this question, this is given that X is more reactive than Y which is more reactive than ZSo, we can place them in reactivity series as X>Y>ZThis means that X can displace Y and Z . Y can displace Z. Z cannot displace any of the other two.

Hence, the correct answer is option B) When metal X is placed in a solution of Z sulfate, a reaction occurs.

Describe in about 100 words your own idea of what it means for characters to have moral complexity.

Answers

Answer:

When reading a story in which the characters do not offer moral complexity, readers do not expect stories to be long. It is expected to find characters with little moral complexity in stories that leave a take away message. However, in novels, the reader expects something more complex. For example, if the story is about a serial killer, it would be good to find, a character who is very intelligent and has a strong family life, but has the underlying and dark life as a serial killer. It is exciting to find a story in which the antagonist is loved and hated at the same time, for example a serial killer who deeply loves his children and his wife. This is that complex characters alleviate contradictions such as the one mentioned above. The person in the story is a serial killer, he is intelligent and has a good family life, those are contradictions that do not make sense for the morality of most readers, they just do not fit into our scheme.

Define the social distance theory in your own words in a paragraph.

Answers

Explanation:

Social distance refers to the level of acceptance people have of others outside of their own social group or class. This level of acceptance is defined by their general feelings toward others, and the amount of social interaction they have with people whose characteristics are outside of their social norm. Social distance is a measure of perceived difference (or distance) among groups. It can be small, for example, when people are accepting of others, or large, when people reject other groups. As a social construct, social distance is a familiar issue. Many common phrases refer to social distance, such as 'out of your league' and 'birds of a feather flock together.' These social norms are ingrained in our collective consciousness.

What is a writer's journal used for? i

Answers

A Journal or Diary means different things to different people.

What used to be a practice of recording personal encounters, events, or challenges of the day in one’s diary is largely referred to as journal-writing, a new term used by many today.

My idea of writing a Journal is a two-part sequence. On one part, I record all the significant daily happenings, from my appointment/event schedules, the type of food & beverage that I consume, to the exercise routine and sleep pattern of the day and how my day turned out, overall. Not by any means paranoia, it’s a private way of monitoring my routine - to endeavor to draw a balance on living the life and lifestyle I designed for myself, and well, also living life to the fullest! My mantra is and has always been - Health, Happiness, and Wealth, in that order; and my Journal helps me to keep things in check. How so? Whenever I input data, it is a process of reviewing what I have done, and whether I have been disciplined enough to keep within the perimeters of my indulgence.

The other part of my diary contains my thoughts - creative thoughts that check on the progress of development of my aspirations - a creative thinking process exploring and examining my personal life and career goals - whether I have achieved them yet, if not, how much more effort I need to put in to realize those goals. It’s a personal checklist and reminder, and sometimes a wake-up call when I re-read old journal entries.

My journal is my friend, companion, and confidante. Depending on how creative and indulgent you are - writing a journal need not be bland text input as in word processing. You can include image clips, videos, and hyperlinks, to make your journal-writing experience more engaging.

Always keep your journal PRIVATE - it is sacred. If you word-process, encrypt your files with password access.

If you are writing pen-on-paper, keep your diary under lock and key.
