what element is found in group 6 and period 4? Based on its location, is the element more similar to tungsten or to iron?

Answers

the asnwer is berlinuim  become a power geek like me  plz itl help u

In a periodic table, there are seven periods and eighteen groups. The element found in group 6 and period 4 is similar to Tungsten.

Periodic table:

The elements are arranged in order of an increasing atomic number. They are placed in the respective groups and periods according to their properties and atomic number.

The element belonging to group 6 and fourth period is Chromium and this element is similar to Tungsten as they both belong to same group.

The elements belonging to same groups are chemically similar. Thus, the answer is Tungsten (W).

Describe the relationship between a boiling point and hydrogen bonds in a substance.

Answers

Hydrogen bonding between molecules(inter mlecular) is one such attractive force. ... In water because of the hydrogen bonding attraction between molecules greater energy is needed to separate them from against their inter molecular attraction, therefore higher boiling point.

The boiling points of molecules with hydrogen bonds will always be higher than those of molecules of similar size without an -O-H or -N-H group.

What is hydrogen bonding ?

When a hydrogen atom bonded to a strongly electronegative atom is in close proximity to another electronegative atom with a single pair of electrons, the hydrogen bond is an intermolecular force (IMF) that results in a unique type of dipole-dipole attraction. There are forces between molecules called IMFs. Dipole-dipole interactions and dispersion forces are two additional examples. While true covalent and ionic bonds are stronger than hydrogen bonds, dipole-dipole and dispersion forces are generally weaker.An organic molecule with an -OH group is called an alcohol. Hydrogen bonds can occur in any molecule that has a hydrogen atom directly attached to an oxygen or nitrogen. When hydrogen is bonded to fluorine, hydrogen bonds also occur, but other molecules lack the HF group. The molecules become as a result of the hydrogen bonding, requiring more heat (energy) to separate. The boiling point of various molecules, which is the temperature at which a phase change from liquid to gas takes place, can be examined using this phenomenon.The ethanol's hydrogen bonding has raised its boiling point by about 100°C. It is essential to comprehend that van der Waals attractions are not the only forms of hydrogen bonding. For instance, each of the molecules that follow has the same number of electrons, and the two that follow have chain lengths that are comparable. Because of the additional hydrogen bonds, the butan-1-ol has a higher boiling point.

A balloon has a volume of 6.25 L at 453 kPa. What would the volume of this balloon be at 325 kPa?

Answers

Answer:

4.48 L

Explanation:

P1/V1 = P2/V2

453/6.25 = 325/ x

453x = 6.25*325

x = (6.25*325)/453

x = 4.48 L

give at least five insights that you learn from this lesson, as your way of recognizing the uniqueness of earth as a planet life

Answers

Answer and Explanation:

The lesson about the uniqueness of the earth allowed me to realize that the earth is the only planet that has drinking water and oxygen, thus allowing the existence of life on the planet and showing that we would not fully survive on another planet.

The lesson also shows that the earth is the only planet where rotation is capable of causing seasonal differences in different parts of the globe. This is important for several things, including food production and plant growth.

Another factor that shows the uniqueness of the land is its favorable temperature for life, allowing us to have water and to be able to live outdoors, for example. This factor is worrying, since the holes in the ozone layer have caused changes in this temperature.

I was also able to learn about the gravity of the earth, which is the only thing that allows us to do all the activities we do and allows us not to be launched into space. In addition, gravity has a strong influence on seas and agriculture.

Finally, I was able to learn about the tectonic plates, which provide the movement of our crust and influence in several geological processes.

b. conduct an experiment, form a hypothesis, make a conclusion, record data
c. form a hypothesis, record data, conduct an experiment, make a conclusion
d. record data, form a hypothesis, make a conclusion, conduct an experiment

Answers

Answer:

a. form a hypothesis, conduct an experiment, record data, make a conclusion

Explanation:

Performing scientific investigations involved following the SCIENTIFIC METHOD, which is a rule or guideline followed in order to discover knowledge about natural phenomena. The scientific method has been divided into steps viz:

- Making observation/asking questions: In this case, the problem is HOW ANTS FEED.

- Formulating hypothesis: The hypothesis is a testable explanation given to solve the asked question.

- Testing hypothesis: The hypothesis must be able to be tested via conducting an experiment.

- Analyze result: The results of the test is recorded and analysed as data.

- Make conclusions: The conclusion either accepts or rejects the hypothesis depending on the result of the experiment.

Therefore, based on this; form a hypothesis, conduct an experiment, record data, make a conclusion are the steps Colby should take to best study the feeding patterns of ants

Write the products of these double-replacement reaction. Then balance each equation. a) NaOH(aq) + Fe(NO3)3 (aq)---> Iron (III) hydroxide is a precipitate

Answers

Answer:

3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)

Explanation:

Step 1: RxN

NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + NaNO₃ (aq)

Step 2: Balance RxN

We need 3 OH's on both sides.

We also need 3 NO₃'s on both side.

This will make it so we also need 3 Na's on both side

3NaOH (aq) + Fe(NO₃)₃ (aq) → Fe(OH)₃ (s) + 3NaNO₃ (aq)

A new scam on the Internet involves people selling samples of sodium that they collected from a secret river in the mountains. Write a short statement to explain why this is a scam.

Answers

Answer:

Explanation:

The reason this is a scam is because they are selling sodium and to sell this product you must have a licence to do so. And secondly, you cant tell the reader that it is from a secret river and sell them a product that reacts when it touches water.

Sodium is a very highly reactive metal that does not occur in free state in nature.

Sodium is a group 1 element. It has a very negative electrode potential which implies that it is highly reactive. Being a highly reactive element, sodium can not occur in free state in nature. It always occurs in combined form as compounds.

Hence, it is impossible to pick up sodium from any secret river in the mountains. Sodium metal is highly reactive hence it has to be stored under paraffin oil. The whole set up is indeed a scam.

Some oxides are given below. (i)Na2O (ii)NO2 (iii) CO2 (iv) MgO a) Which are the basic oxides among these? b) What is the name of the aqueous solution of CO2 ?

Answers

Further explanation

Basic oxides ⇒ metal(usually alkali/alkaline earth) +O₂

L + O₂ ⇒ L₂O

L + O₂ ⇒ LO

Dissolve in water becomes = basic solution

L₂O+H₂O⇒ 2LOH

LO + H₂O⇒ L(OH)₂

So the basic oxides : Na₂O and MgO

Na₂O + H₂O⇒NaOH

MgO +H₂O⇒Mg(OH)₂

The aqueous solution of CO₂(dissolve in water)

CO₂ + +H₂O⇒ H₂CO₃(carbonic acid)
