Question 1 Of the following which displays a positive energetic process?

1 answer:

5 0

We can describe a positive energetic process as any process which increases the internal energy of the system.

A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:

Boiling an Egg
Roasting food over a fire (the food is the reference system)

etc

Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.

Since I could not locate the options online, I have provided a general explanation of the concept coupled with a few examples.

Humans and Animals will be affected differently in many ways. The construction of roads has to access logging, oil, and mining sites in the forest. These roads are funded by government and development agencies, some are financed by private companies or development interests.

For humans, it is somewhat better because the food products come from rainforests as well, such as bananas, citrus, cassava, avocado, cashews, Brazil nuts, vanilla, sugar, coffee, tea, and cocoa. Medicine also comes from the rainforest, some of the ingredients for medicine come from the plants. So do materials such as rubber, oil, gum, resins, and paper. However, if we grew more farms and gardens we would be able to provide food from those gardens and farms, it will take more work, but it will be worth it. Using the products in the rainforest, it's a bad thing and a good thing. The food and materials help survive, yet it could kill the forest and places for animals to live in.

There are many roads that are being built or upgraded, it's a good thing because it can be a lot safer for us, humans, to drive in. But again, they won't be able to fix all the roads, and adding roads in the rainforest would be a waste of time and just kill the animals and the forest itself. It can help the people in the forest much more, but as we see, the people also survive that way. Road construction in the forest can cause impede streams, increase forest flooding, and drastically increase soil erosion. If that happened fish can die out and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

If we did keep the roads paved at all times, it can save money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a new study. Many parts of the world are increasingly the result of political pressure from corporate interests, namely loggers, mining companies, oil and gas developers, and industrial agricultural firms, rather than government-backed poverty alleviation and development efforts.

The deforestation of rainforests can be a big and devastating effect on our world. It can lead to many animals getting extinct, which is happening as of today. It also decreases the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. It can also have a huge effect on our climate, and climate can destroy animals, like in the Arctic.

How many moles of a gas would occupy 22.4 Liters at 273 K and 1 atm?

Molodets [167]

Answer:

1 mole of a gas would occupy 22.4 Liters at 273 K and 1 atm

Explanation:

An ideal gas is a set of atoms or molecules that move freely without interactions. The pressure exerted by the gas is due to the collisions of the molecules with the walls of the container. The ideal gas behavior is at low pressures, that is, at the limit of zero density. At high pressures the molecules interact and intermolecular forces cause the gas to deviate from ideality.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case:

P= 1 atm
V= 22.4 L
n= ?
R= 0.082 $\frac{atm*L}{mol*K}$
T=273 K

Reemplacing:

1 atm* 22.4 L= n* 0.082 $\frac{atm*L}{mol*K}$ *273 K

Solving:

$n=\frac{1 atm* 22.4 L}{0.082 \frac{atm*L}{mol*K} *273 K}$

n= 1 mol

Another way to get the same result is by taking the STP conditions into account.

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

1 mole of a gas would occupy 22.4 Liters at 273 K and 1 atm

How much heat is needed warm 65.34 g of water from 18.43 to 21.75

BaLLatris [955]

Given that

Mass of water = 65.34 g

Amount of heat = mass of water * specific heat (temperature change

)

= 65.34 g * 4.184 J / g-C ( 21.75-18.43 )C

= 907.63 J

= 0.908 KJ

And

1 cal = 4.186798 J

907.63 J * 1 cal / 4.186798 J =216.78 cal

Or0.218 kcal
