Answer:

THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.

Explanation:

Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.

Mathematically, P1 V1 = P2 V2

Write out the values of the variables given:

P1 = 2.4 atm

V1 = 1.8 L

V2 = 1.5 L

P2 = unknown

Re-arranging the variables by making P2 the subject of the equation, we have:

P2 = P1 V1 / V2

P2 = 2.4 * 1.8 / 1.5

P2 = 2.9=88 atm

Hence, the pressure exerted by the gas is therefore 2.88 atm

How is the potential (voltage) of a redox reaction determined using the reduction
LuckyWell [14K]

Answer:

caused by the ability of electrons to flow from one half cell too the other

Explanation:

How is the potential voltage of a redox reaction?

The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. A redox reaction occurs when a certain substance is oxidized, while another is reduced.

The diagram shows the process of the water cycle on Earth. Heat from the Sun causes water to evaporate: the liquid water turns i
astra-53 [7]

The diagram below shows the different aspects of the water cycle, such as how water is observed by plants and how it is carried around by the atmosphere.

The diagram relates to a cactus biome.

Cactuses are still plants,

We have several characteristics that make cactus a plant:

1. Photosynthesis

Unlike other plants that photosynthesize with their leaves, cacti do so with their stems. At night, they take in carbon dioxide, which is then used during the day.  

2. The stem succulent

A cactus is classified as a succulent. In other terms, a succulent is a plant that has thick juicy stems or leaves that store water. A cactus stores its water in stems, and some species are adapted to arid areas.  

3. Special skin surface

One attribute that makes cacti not lose a lot of water is the fact that they have waxy surfaces that prevent evaporation. Some species also have ribbed surfaces that prevent splitting even when the plant expands during desert rainstorms.

4. Cactus spines

Cacti have spines that protect them from being eaten by animals. The spines also act as insulation during the dry seasons.

How do cactuses survive in the desert?

A cactus is able to survive in the desert due to the following features:

It has long roots that go deep inside the soil for absorbing water.

Its leaves are in the form of spines to prevent water loss through transpiration.

Its stem is covered with a thick waxy layer to retain water.

This shows how cactuses can survive without water and this relates to what the diagram shows however, the diagram shows that rain takes a part in the water cycle, whereas for cactuses, they don't need much water due to their extreme adaptivity.

But there are some similarities too, for example cactuses are still plants so they still photosynthesise and give us oxygen and whatnot.

Forgive me if this is wrong, I tried my best <3 Have a great day

Electrons in conductors, like copper wire, are free to roam throughout the metal in the presence of the ions that have released
Scrat [10]

Answer:

  • <u><em>No, I would not consider a metal to be a plasma because plasma is just another state of matter, and the copper wire is in solid state.</em></u>

Explanation:

Metal is not a state of matter. Metals can be solid or liquid (molten) depending on their melting point and the temperature at which they are.

Plasma is a state of matter, similar to gas, but it is reached only at very high temperatures like in the Sun. The particles in plasma state are not neutral atoms or molecules but negatively charged  ions and electrons.

The copper wire is yet a solid, thus it cannot be considered a plasma.

Metals can be in plasma state only if the temperature is too high, like the temperatures in the stars. In fact, the metals in the Sun and other hotter stars are in plasma state.
