Answer 1

Answer:

Explanation:

1. H2O

Lewis Dot:

See the attachment.

Note the б+ and б- signs on the H and O atoms, respectively. Those represent the slightly positive and slightly negative sides of the water molecule. Those slight charges on a single water molecule are attracted to their opposite charges on neighboring H2O molecules, as shown in the graphic. This interaction is what gives water it's cohesive properties.

3. The property of cohesion describes the ability of water molecules to be attracted to other water molecules. which allows water to be a "sticky" liquid.

The hydrogen bonds are attractions of electrostatic force. They arise due to the difference in charge between the slightly positive hydrogen ion and the slightly negative oxygen ion. Hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond, and it is what gives water it's cohesiveness, or ability to support water spiders, paper clips, and produces a loud noise in the event of a belly flop in a pool (including the yelp from the swimmer).

4. I'm not sure what is being asked for the two blanks. Water is polar and dissolves salts (ionic compounds) and hydrophilic molecules (water-loving molecules).

Find the density of an 8 gram rock if the water in a graduated cylinder rises from 25.0 mL to
29.0 mL when the rock is placed in to the graduated cylinder.

Answers

To measure the density of the stone placed in a graduated cylinder let us follow these steps bellow

Measure the volume of water poured into a graduated cylinderPlace the object in the water and remeasure the volume. The difference between the two volume measurements is the volume of the object. Divide the mass by the volume to calculate the density of the object.

We know that the formula for density is given as

Given data

Mass = 8gram

Initial Volume of water in cylinder = 25mL

Final Volume of water in cylinder = 29mL

Hence the volume of the rock = 29-25 = 4mL

Therefore the density of the rock = 8/4 = 2 g/mL

A sample of Ar gas occupies a volume of 1.2 L at 125 degrees * C and a pressure of 10 atm. Determine the temperature , in degrees Celsius, at which the volume of the gas would be 1.0 L at the same pressure .

Answers

Answer:

58.64

Explanation: You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so pressure and I assume moles (since it was not mentioned as a change). You want to change the temperature to Kelvin (always) to do work, then you can solve algebraically for the answer! Once you have your answer change it to Celsius since that's what you were asked for.

Which statements best describe the functions of nucleic acids and proteins?.

Answers

The statement describing nucleic acid has been that nucleic acid provides the blueprint for the formation of proteins.

Nucleic acid has been the genomic material in the body that performs the function of storage of information. DNA and RNA are nucleic acids.

The proteins are the biomolecules that are composed of amino acid units bound by the polypeptide bond. The information for the correct sequence of binding of protein has resulted from the mRNA codes.

The correct sequence and folding results in the operational protein, that has been able to perform varying functions. The codes for the binding of protein have resulted from the blueprint consisting of nucleic acid.

Thus, nucleic acid performs the function of acting as a blueprint for the formation of proteins.

Mrs. Nelson is very tech-savvy and uses many forms of social media to communicate with her parents and students. At the beginning of the year, she asks parents to follow her on a communication app, Remind, so that they can receive important text reminders about upcoming events. Remind is typically used for group communication, for example, Mrs. Nelson might send out a reminder to the class that they have a field trip and will need to remember their lunches. After receiving a group text, parents then have the option to respond individually to Mrs. Nelson and they can then carry on a conversation in a private environment if they need to discuss more student-specific information.Many of her students have their own cell-phones and have also begun following Mrs. Nelson the Remind app, and while does not encourage this, she doesnt remove them when they do. It has never been an issue in the past, and she assumes it might help them to know what is going with upcoming and important events too.Mrs. Nelson is a very loved and respected teacher, and she is known for providing a very safe and nurturing environment in her classroom. Whenever a student is struggling with anything, they always know that Mrs. Nelson will listen and support them. Because of the precarious nature of 5th grade, students often come to Mrs. Nelson with all kinds of problems. After sending out a Remind text about the upcoming early dismissal day, a student, Maddie, responded with a private message to Mrs. Nelson telling her that she needed to talk to her about a problem. Mrs. Nelson tells her to come to her first thing in the morning, so they can talk before class begins. The next morning, Maddie shows up early to class as instructed, and tells Mrs. Nelson that she thinks something is wrong with her because she doesnt like boys the way her friends do, and but she really doesnt want to be gay. She is afraid of what her parents and friends would say if she never likes boys the way she thinks she is supposed to. Though she was a little taken aback by this confession, Mrs. Nelson assures her that she will be ok, and that it is ok that she doesnt have the answers to those questions right now. Thinking about it later that evening, Mrs. Nelson, was concerned that she hadnt been supportive enough in talking with Maddie, so she sends her a private Remind text saying, "I want you to know that you are a very smart and beautiful young lady, and if you like boys or girls, that wont change. I wont say anything to anyone about our conversation."Questions:1. Identify the behaviors (if any) that you believe violate standards in the Educator Code of Ethics?2. Which standards do you think were violated, explain your reasoning. If you feel that no standards were violated, explain your reasoning?3. Should Mrs. Nelson have handled this situation differently so as not to violate the Code of Ethics, or (if you feel that there was no violation) to avoid her actions being called into question?
