A fixed mass of gas has a volume of 92 cm cube and 3 degrees Celsius. What will be its volume at 18 degrees celsius if the press
8090 [49]

Answer:

94.8454

Explanation:

Let volume be V

Let Temperature be T

V1= 92

T1= 3C but to kelvin 273+3= 300K

V2= ?

T2= 18 C but to kelvin 18+273= 291

\frac{v1}{t1}  =  \frac{v2}{t2}

\frac{92}{300}  =  \frac{v2}{291}

v2 \times 300 = 92  \times 291

v2 =  \frac{92 \times 291}{300}

v2 = 94.8454

40 POINTS PUT A GOOD ANSWER
Andreyy89

Answer:

<u>B</u> What role do animals have in the carbon cycle?

Group of answer choices

use water and release oxygen

<u>use sugar and release carbon</u>

use carbon and release oxygen

use carbon and release nitrogen

<u>D, E</u> Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.

Group of answer choices

There is more available space for carbon to become fossil fuels.

There is less carbon in storage.

There will be less carbon in the water.

<u>There is more carbon in the atmosphere.</u>

<u>There will be more carbon respired by organisms.</u>

There will be less carbon released through decomposition.

Explanation:

Animals obtain energy through sugar from the food they eat and release carbon into the air through respiration. Therefore, they partake in the carbon cycle by using sugar and releasing energy.

As far as the second question, when fossil fuels are burned, the carbon contained within them is released into the atmosphere in the form of carbon dioxide. So, there will obviously be a greater amount in the atmosphere.

I would like to apologise in advance if either of my option choices were incorrect.

What is the mass of the light bulb and paperclips together? a. 250.1 g b. 246.0 g c. 251.0 g d. 205.10 g
ololo11 [35]

251.0 is the correct mass  of the light bulb and paperclips together.

<h3>What is mass ? </h3>

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

For a body, mass is constant. Mass can be calculated using the formula: mass = volume density. A mass's weight is a measurement of the gravitational force at work on it. The kilogram is the SI unit of mass.

The mass of the substance will therefore be calculated as follows: MASS OF A SUBSTANCE = VOLUME DENSITY.

So finally we can say that the mass of the light bulb and paperclips together is 250.1g.

Which atom would tend to gain 1 valence electrons from another atom in order to become stable
Mrrafil [7]

Answer: Option (D) is the correct answer.

Explanation:

Atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.  

So, in order to attain stability it tends to gain one electron from a donor atom. Therefore, a chlorine ion is formed as Cl^{-1}.

As it gains only one electron that is why, -1 charge occurs.

Whereas Ar is a noble gas with atomic number 18. As it has completely filled octet so it will be unreactive in nature as it is already stable.

Similarly, He is also a noble gas so it is unreactive in nature.

Atomic number of boron (B) is 5 with electronic distribution 2, 3. So, in order to attain stability it needs to lose 3 electrons.

Thus, we can conclude that Cl is the atom which tends to gain 1 valence electron from another atom in order to become stable.
