The thermochemical equation for the formation of ammonia (NH3) is shown below. How much energy (kcal) is released when 6.0
mol of H2 reacts?
(Note - when the direction of energy flow is indicated, e.g. "released", the negative sign is not used in the answer.
3 H2(g) + N2(g) →2 NH3(g) triangleH = - 11 kcal
Answers
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.
Let's consider the thermochemical equation for the formation of ammonia.
3 H₂(g) + N₂(g) → 2 NH₃(g) ΔH = - 11 kcal
As we can see, 11 kcal are released when 3 moles of H₂ react. The heat released when 6.0 moles of H₂ react is:
[tex]6.0molH_2 \times \frac{(-11kcal)}{3molH_2} = -22kcal[/tex]
In the formation of NH₃, -22 kcal are released when 6.0 moles of H₂ react.

Use metric and U.S. conversion factors to solve the problem.
Question - If a student is 175 cm tall, how tall is the student in meters?
Answers
Explanation:
100cm = 1m
1cm=1/100 m
175cm = 175/100 m = 1.75m.
hope this helps you.
If a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.
What is a Metric system?A metric system may be defined as a type of system that significantly weighs and measures the mass and distance respectively in which the meter is the unit of length and the kilogram is the unit of weight.
A metric system is a standard system of measurement which utilizes the meter, liter, and gram as base units of length for distance, capacity for volume, weight for mass, etc.
According to the question, the height of a student in cm = 175 cm.
Then, from the general conversion rule,
1 meter = 100 cm.
1 cm = 1/100 meter.
175 cm. = 175/100 = 1.75 meters.
Therefore, if a student is 175 cm tall, then according to the metric system the same student is 1.75 m tall.

Which of the following represents the velocity of a light wave?
O A. E = fx2
O B. c = hxf
O C. E = hxf
O D. c = fx2
Answers
Answer:
D. c = fλExplanation:
c = fλ
where" c "is the speed of light ,
• "f" is the frequency of the electromagnetic waves,
• " λ" is its wavelength.
The term that represents the velocity of a light wave is c = fx2. The correct option is D.
What is velocity?Velocity is the speed by which an object moves or do any motion. When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
Light waves are the movement of waves in a direction. There are two types of transverse and electromagnetic. They are divided on the way of their movement.
The velocity of the light wave is the speed at which the light wave moves in a specific direction in time. The formula is given below:
c = fλ
Where c is the speed of light.
f is the frequency of the electromagnetic waves,
λ is its wavelength.
Thus, the correct option is D. c = fx2.

how many valence electrons does alkali metals gain or lose
Answers
Answer:
Alkali metals have 1 valence electron on their outer shell. They are more stable when they have 8 valence electrons, so they want to lose that valence electron. They do this by bonding with other elements. When they lose their 1 valence electron, they have a full octet and are therefore stable.:
Which substance tends to form anions when bonding with other elements?
sodium
oxygen
argon
calcium
Answers
Answer:
B) Oxygen
Explanation:
i just took the test.
Any species that contain negative charge over it called anion. Out of sodium, oxygen, argon and calcium, oxygen is the only element that can form anion. So option B is correct option.
What are non metals?Non metals are the element that have property to gain electron. When any element gain electron then element attain negative charge and that element is called anion.
In our question sodium, argon belongs to metals category and these lie on the left side of the periodic table. Metals are meant to release electron and hence become cation.
Argon is non metal but it is a noble gas which has property to not to react as its octet is complete. Thus the only element that is non metal here is Oxygen that forms anion. Its oxidation state is -2. Thus option b is correct option
