There is a ozone layer because of the special atomphere and chemical conditions that takes place there. I think the consequences of that home area is the very low winter temperatures.

Answer:

There is a hole in the ozone layer because of the pollution on earth. Because of that the UV rays are easily entering the earth through that portion. The consequences of this can be cancers, global warming and disastrous storms.

Explanation:

0.25 M

The molarity of a solution will be 4.27M .

Molarity (M), often known as molar concentration, is the concentration of a solution expressed in moles of solute per liter of solution.

Solution can be considered as a mixture of more than one component. It may be homogeneous solution as well as heterogeneous solution.

Gram to mole conversion:

[tex]=\;2.75\;g.\;\frac{1\;mol}{58.44g} \\=\;0.0470 \;mol[/tex]

Molarity of the solution can be calculated by using the following formula:

It is calculated that, moles of solute = 0.0470 mol, volume of the solution = 1100 mL.

Now, put the value of given data in molarity formula:

[tex]Molarity=\frac{Moles\;of\;the\;solute}{Volume \;of\; the\; solution} \\=\frac{0.0470\;mol}{1100 \;mL} \\=\;4.27\;mol/mL\\=\;4.27\; M[/tex]

Therefore,  the molarity of a solution will be 4.27M.

Answer:

Increased

Explanation:

We know that the higher the temperature the higher the rate of reaction. This implies that as the temperature is increased, a reaction tends to proceed faster.

This follows from the collision theory, the higher the temperature, the higher the energy of the reacting particles hence they collide with each other faster and more effectively.

Thus the rate of reaction( or reaction time) for the carton of milk on the counter was increased.

A 6.0-V battery does 1200 J of work transferring charge, then 100C charge is transferred.

One or more electrochemical cells with external connections for powering electrical equipment make up an electric battery, which is a source of electric power.

A battery's positive terminal serves as the cathode and its negative terminal serves as the anode when it is delivering electricity.

Electricity is accepted, stored, and released on demand by batteries and similar devices. Like many other common energy sources, batteries store energy through chemistry in the form of chemical potential.

For instance, until they are burned, logs store energy in their chemical bonds for later conversion to heat.

V = 12 V

W = 1200 J

q = ?

V = W / q

12 = 1200 / q

q = 100 C

Thus, A 6.0-V battery does 1200 J of work transferring charge, then 100C charge is transferred.

Explanation:

The ball of 21.7 kg which is located on a shelf 1.6 m above ground is having a mechanical energy in the form of potential energy. Hence, C best describes the energy of the ball.

Potential energy is the energy stored on it when the object is at rest. Kinetic energy of an object is generated by virtue of its motion. When a body starts moving its potential energy starts converts to kinetic energy.

The sum of kinetic and potential energy of an object is called its mechanical energy. An object has mechanical energy in the form of kinetic energy when it is at rest. When it starts to move its potential energy converts to kinetic energy.

Therefore, the ball of 21.7 kg placed in the shelf of height 1.6 m has a potential energy as long as it stays there on the shelf. Its potential energy = mgh

p = 21.7 kg × 9.8 m/s² × 1.6 m = 340.25 J

Explanation:

A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It's that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.

Answer:

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.

Explanation:

We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.

All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

A DAY IN THE LIFE OF METIS JOURNAL. I WROTE IT HOPE U LIKE IT XD

We, who live in the west, were Nomadic. So we always moved from place to place to hunt buffalo and other fur-bearing animals. And now again we have to shift everything we collected , like, all the essential needs we collected. It’s really hard to shift stuff, But when you move to a new place you get to see new beautiful places. They are just so satisfying to see! It’s like all my work(like the shifting work) is paid off. I love it! We always meet the Hudson’s bay company employees, and give them furs which we took from the bissons and other furry animals we hunted. And in exchange they give us their (Hudson’s Bay company) goods. Which is good! Because then we or I won't be able to enjoy that delicious pemmican!

 The one reason that makes me proud of my parents is that because of them I am like a translator for both sides in the fur trade! Anyways coming back to the present. As I said before, we were moving today to another place, But on the way some people along with my father will ride the famous York boats carrying supplies to fur posts. I begged my father to take me with him! And as usual he gave me some silly reason for me to stay. And now since I don’t have anything to do I will-..Nevermind, My mom’s calling me. Okay after helping my mom keep the fur posts into the York boats me , my mom, and the others are just relaxing and enjoying nature just to take a break. Since, I am so obsessed with my Journal notebook today I’m just going to sit here and right what comes to my mind. I’m not like the others who always seem to be talking with someone. I like my own space! 

I kind of miss my dad already, but he and his fellow members need to travel the waterways from the red river further west and north to hudson bay. These red river carts also travel the trek back and forth over land to St. Paul, Minnesota and to posts in saskatchewan.  Speaking about the red river, the only large settlement in the region is the red colony. About 12000 people lived in this colony around Fort Garry. Some were the original Selkirk settlers or their descendents. They had come from Scotland with lord Selkirk when he established the colony in 1811. Many of these original settlers were poor farmers who had been displaced  from their lands in scotland. They had endured many hardships in the early years of settlement, including foods, hunger, and sickness. I love studying about other colonies, cultures , history etc.
