The decomposition of ammonia gas (a process that occurs at high temps) is 2KH3(g) --> N2(g) 3H2(g). If a balloon was filled with 3.5L of ammonia gas and all of the gas decomposed, what would be the total volume of gas in the container? Assume the pressure and temp remains constant.

Answers

Answer 1

Answer: Ammonia gas is $\text{NH}_3$ .

Since the ammonia gas took up 3.5 L at first, using Avogadro's Law, we know that 2 mols of a gas took up 3.5 L at first, but now there are 4 mols of gas in total after the decomposition. Therefore, we can conclude that now the volume in total is 7 L.

Answer 2

Answer:

Answer : The total volume of gas in the container will be, 7 liters

Explanation :

The given balanced chemical reaction is,

$2NH_3(g)\rightarrow N_2(g)+3H_2(g)$

From the balanced chemical reaction we conclude that

2 mole of ammonia gas decomposes to give 1 mole of nitrogen gas and 3 moles of hydrogen gas.

According to the Avogadro's Law, the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

$V\propto n$

or,

$(V_1)/(V_2)=(n_1)/(n_2)$

where,

$V_1$ = initial volume of ammonia gas = 3.5 L

$V_2$ = total volume of gas in the container = ?

$n_1$ = initial moles of ammonia gas = 2 mole

$n_2$ = final moles of all gas (nitrogen + hydrogen) = (1 + 3) = 4 moles

Now put all the given values in the above formula, we get the total volume of gas in the container.

$(3.5L)/(V_2)=(2mole)/(4mole)$

$V_2=7L$

Therefore, the total volume of gas in the container will be, 7 liters

Answers

Final answer:

The experiments 'The Iced Tea Debate' and 'The Salty Soup' illustrate different physical changes and energy transfers in the context of the Law of Conservation of Matter and Energy.

Explanation:

In 'The Iced Tea Debate', the independent variable could be the temperature of the tea, the dependent variable could be how quickly the ice melts and the control variable could be the amount of tea used in each trial. The Law of Conservation of Matter and Energy states that matter and energy cannot be created or destroyed in an isolated system. In this case, the ice melting is a physical change, and the energy transferred is thermal energy from the tea to the ice.

In 'The Salty Soup,' the independent variable could be the amount of salt added, the dependent variable could be the taste of the soup, and the control variable could be the type of soup used. The added salt dissolving into the soup is a physical change, and no noticeable energy transfer occurs.

One example of conservation of matter and energy in everyday life is the process of photosynthesis in plants. The plant absorbs sunlight (energy), carbon dioxide, and water, and converts them into glucose and oxygen, thus conserving matter and energy.

Final answer:

In these demonstrations, matter and energy were conserved, as total mass and energy stayed constant. Significant phase and energy transformations were observed, like the melting of ice and the dissolving of salt. The total mass before and after the transformations remained the same, demonstrating the law of conservation of mass.

Explanation:

Matter and energy can be described as being conserved in a variety of systems because they can neither be created nor destroyed, only transferred between objects or converted from one form to another. In 'The Iced Tea Debate' and 'The Salty Soup' demonstrations,

Variables would include: Independent variable: the substance added (be it ice tea or salt); Dependent variable: physical and chemical changes observed; Control variables: the initial conditions of the system, like temperature and pressure.

When analyzing the results of each of these demonstrations, you should observe energy transfers, in the form of heat in both scenarios.

Moreover, there would be conservation of matter observable in both scenarios. This can be proven by extracting and weighing all substances before and after their reactions, summing up the total mass, which should stay constant.

To answer the questions:

In each demonstration, matter was conserved as the total mass remained constant despite the transformations. Energy was conserved as it was converted from one form to another.
Phase changes observed would be the melting of ice in the Iced Tea and the dissolving of salt in the soup.
Energy transfer in both scenarios was likely in the form of heat, from the hotter substance to the colder one.
An example of matter and energy conservation in the world around you could be photosynthesis.

True or False: Plants don't have brains, but they still adapt to their environments.

Answers

True, Plants don't have brains, but they still adapt to their environments.

What is adaptation?

Adaptation is a process where they are changing their nature to suit the environment.

We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.

Hence, plants have no brains, but they still adapt.

If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature?

Answers

Okay so according to the formula PV=nRT
n=4
P=5.6 atm
V=12 L
R=0.08206 L atm mol-1 K-1
T=?
So, if you plug it in, you will get:-

T=PV/nR
T=(5.6 atm)(12 L)/(4 mol)(0.08206 L atm mol-1 K-1)
T=204.73 K

Hope I'm right! :)

Answer:

PV=nRT

Explanation:

T=PV/nR

P=5.6atm n= 4 mol V=12 L R =.082Latm/K mol

T= (5.6 atm)(12 L)/(4 mol)(.082Latm/K mol)

T = 205 K = -68 C
