Nitrogen gas (N2) and hydrogen gas (H2) react to produce ammonia (NH3).
If we have 2 mol of N2, how many moles of NH3 will be produced?
1 mol NH3
2 mol NH3
3 mol NH3
4 mol NH3

Answers

Answer 1

Answer:

I believe it would be 2

Explanation:

if there are 2 nitrogen molecules then there would have to be 2 hydrogen molecules but this could be completely wrong

if this happens to be right, ur welcome :3 here's a Jay Jay pic for u cuz why not

During an experiment, four different elements were added to water and observed. Element C showed no reaction. The other three elements bubbled, with Element D bubbling with the greatest vigor and Element A bubbling the least. Which list orders the elements from least reactive with water to most reactive with water?

Answers

Answer:

In order most reactive to least reactive:

D

B

A

C

Explanation:

The reactivity series is depend on the element that reacts with the oxygen. The metal which replaces the other metal is a more reactive metal.

In the question, there are different metals and we have to find the reactivity series of the unknown metal

The series in decreasing order is as:- D  > B  > A  > C.

In this reaction, the upper element replaces the lower elements because it is highly reactive.

Hence, the correct sequence is D  > B  > A  > C.

A cold can of soda is taken out of the refrigerator. It slowly warms up until it is at room temperature. Once the soda has warms up, it has more thermal energy than it had in the refrigerator. Where did this additional thermal energy come from?

Answers

Answer:

See explanation

Explanation:

We know that the thermal energy of a substance largely depends on the temperature of the body. This implies that the hotter a substance is, the greater its thermal energy and vice versa.

When you bring a cold can of soda out of the refrigerator, the molecules of air at room temperature gradually loose energy to the can and condense around it. This transfers thermal energy from the air particles to the molecules in the cold can of soda and the soda warms up pretty soon!

An element with atomic number 18 is a noble gas.Into which family you shall place elements with atomic number 17 and 19 and why?

Answers

Answer:

Explanation:

An element with atomic number 18 is a noble gas.

The element with atomic number 19 will have one extra electron so it can donate one electron or shed one electron to attain noble gas configuration .

It tends to shed one electron to become positively charged ion . Hence they are electro-positive elements .  

Similarly the element with atomic number 17 will have one short  electron so it can gain  one electron  to attain noble gas configuration .

They  tend to gain  one electron to become negatively charged ion . Hence they are electro-negative  elements . They have high  electronegativity .

Potassium is involved in the health of cells and of blood vessels, so its reactivity has increased values, being used by scientists for blood pressure as well as lethal injection, enough could cause your heart to stop. Take bananas for example, they contain potassium, enough for humans.

Explanation:

It was determined that Plan B would likely limit habitat disruption better than Plan A. State officials, however, decided to go with Plan A. Why did the state officials probably choose Plan A?

Answers

Answer: The economic demands of Plan B were too high.

Explanation: During the selection of any action plan to maintain biodiversity, several factors must be considered. These factors include the cost of the plan, the estimated effectiveness of the plan at protecting the targeted populations, and how the plan will affect both humans and other populations in the area.

The chart shows that the approximate cost of implementing Plan A was $5 billion. The approximate cost of implementing Plan B was $30 billion. While Plan B might have been more effective at reducing habitat destruction, and thus maintaining biodiversity, state officials likely chose Plan A over Plan B because the economic demands of Plan B were too high.

Answer: The economic demands of Plan B were too high.

Explanation:

Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.

What is oil?

Any chemical compound that is nonpolar, predominantly hydrocarbon-based, hydrophobic, and lipophilic is considered to be an oil. Typically combustible and surface active, oils. Most oils are lipids which become liquid above room temperature and are unsaturated. Classes of chemical substances that may be unconnected in structure, characteristics, and usage are included in the general concept of oil.

They are employed in the production of numerous varieties of paints, plastic bottles, and various other products, as well as for usage as food (such as olive oil), fuel (such as heating oil), lubricant (such as motor oil), and medical uses. Some religious rituals and ceremonies employ specially formulated oils as cleansing elements. Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.

Therefore, oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.

The energy of the surroundings (outside the pack) will:

a. The energy increases, when energy is released.

Energy in the surroundings:

Energy is delivered to create bonds, which is the reason the enthalpy change for it is positive to break bonds. Energy is expected to break bonds. Particles are a lot more joyful when they are "wedded" and discharge energy since it is simpler and more steady to be seeing someone.

When energy is released, the energy in the surroundings will increase.

Number the steps in the correct order to show how ice changes into gas. __ The molecules gain enough kinetic energy to leave their solid form. __ The water becomes liquid and gets hotter. __ Ice is heated and the molecules speed up __ The molecules leave their liquid form and enter the air as a gas. __ Ice molecules vibrate in a fixed place.

Answers

Answer: Please find answer in explanation column

Explanation:

Numbering the steps in the correct order to show how ice changes into gas, we have that

1.Ice molecules vibrate in a fixed place.

2. Ice is heated and the molecules speed up

3. The molecules gain enough kinetic energy to leave their solid form.

4.The water becomes liquid and gets hotter.

5. The molecules leave their liquid form and enter the air as a gas.

Ice is the solid form of water  which cannot freely move around in this form  so  it vibrates  about its fixed position.When heated,its molecules acquire energy and its vibration  speeds up  causing it to overcome its  binding forces (that makes it vibrate about a fixed position) and becomes mobile as it leaves its solid form to acquire a liquid state.    With continuous heating, the liquid gets hotter making the molecules vibrate more rapidly, spread out and move freely at high speeds to form Water vapour - The gaseous state of water.
