Answer:

Atomic size decreases on going along a period from left to right because the electron enters into the same shell, therefore, attraction between nucleus and outermost electron increases and thus atomic size decreases. Valency first increases from 1 to 4 and then decreases from 4 to GO along a period from left to right.

Answer:

228.4 kPa

Explanation:

From thw question,

PV/T = P'V'/T'..................... Equation 1

Where P = Inital pressure, T = Initial Temperature, V = Initial Volume, P' = fInal Pressure, V' = Final volume, T' = Final Temperature.

Make P' the subject of the equation

P' = PVT'/TV'...................... Equation 2

Given: P = 115 kPa, V = 15.0 dm³, T = 33°C = (33+273) K = 306 K, T' = 51.2°C = 51.2+273 = 324.2 K, V' = 8.00 dm³

Substitute these values into equation 2

P' = (115×15×324.2)/(306×8)

P' = 228.4 kPa.

Answer:

196 grams

because ^^^ was wrong and person in comments said it was 196 and it was right

When NaOH of 4.00 g is being added with water, the mass of water required to create 2.00% of NaOH solution by mass is 196 g.

It means that the particular amount of solute in terms of percentage is present in the solute.

Given the mass of the solute, NaOH is 4.00g

Suppose the mass of water required to add is x in g.

The mass percent of the solute is

[tex]\dfrac{2}{100} =\dfrac{4.00}{4.00 +x }[/tex]

x =196 g

Therefore, mass of water required to create 2.00% of NaOH solution by mass is 196 g.

Answer:

Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.

Answer:

By using the techniques of archeology.

Explanation:

Students recover an individual's remains from a surface grave by using the techniques of archeology field to scrape away the layers of soil from that remains in a way that the remains can't be damaged. If they find the remains within 10 centimeters of digging, they can dig down further in order to dig out all the remains safely. The instruments of archeology field are used because they are light and can be used to dig out fossils of ancient organisms.

Answer:

You will need to have a red flower in the top left, a pink flower in the top right and bottom left, and a white flower in the bottom right.

Explanation:

This flower appears to express color through codominance, which means that both genes express themselves. "R" is the dominant gene for red, and "r" is the recessive gene for white. When a flower has RR genotype, the phenotype will be a red flower. When a flower has an Rr genotype, the red and white genes will both be expressed and the phenotype will be pink. When a flower has an rr genotype, it lacks the red gene and will therefore be only white.

Per cent composition of Magnesium (Mg) in Magnesium Phosphate compound ie [tex]Mg_3(PO_4)_2[/tex] is 27.74%. Hence, option C is correct.

Percent is from the Latin adverbial phrase per centum meaning “by the hundred.”

Determination of the percentage composition of Mg in Mg₃(PO₄)₂

Molar mass of Mg₃(PO₄)₂ = 262 g/mol

Mass of Mg in Mg₃(PO₄)₂ = 24×3 = 72 g

Percentage composition of Mg =?

[tex]Percentage = \frac{Mass \;of \;elements x 100}{Mass \;of \;compound}[/tex]

[tex]Percentage = \frac{72 X 100}{262}[/tex]

27.74%.

Hence, option C is correct.

Explanation:

“Many of the objections are long standing but apparently unknown to many geophysicists, while some are peculiar to the new global tectonics. The conclusions drawn, in order of probability, are (1) the continents have almost certainly not moved with respect to each other; (2) convection is not active throughout the whole mantle; (3) even if convection is active in the upper mantle it cannot account for drift; (4) pole positions derived from paleomagnetism, and results of this method of investigation in its global form generally, are afflicted with an unknown cause of error and are in any case too inexact for drift reconstructions.”

The mass of NaHCO₃ needed to produce 2.659 moles of CO₂ is 446.712 g

We'll begin by writing the balanced equation for the reaction. This can be obtained as follow:

2NaHCO₃ —> Na₂CO₃ + CO₂ + H₂O

Molar mass of NaHCO₃ = 23 + 1 + 12 + (16×3)

= 84 g/mol

Mass of NaHCO₃ from the balanced equation = 2 × 84 = 168 g

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

With the above information, we can obtain the mass of NaHCO₃ needed to produce 2.659 moles of CO₂. This can be obtained as follow:

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

Therefore,

Xg of NaHCO₃ will decompose to produce 2.659 moles of CO₂ i.e

Xg of NaHCO₃ = 168 × 2.659

Xg of NaHCO₃ = 446.712 g

Thus, 446.712 g of NaHCO₃ is needed to produce 2.659 moles of CO₂.

Explanation:

Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.

In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.

An image of the oxygen molecule is attached to this answer.

This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).

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.
