Answer : The final volume of the gas is, 1166.67 ml

Explanation:

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

V\propto T

or,

\frac{V_1}{T_2}=\frac{T_1}{T_2}

where,

V_1 = initial volume of gas = 500 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 150 K

T_2 = final temperature of gas = 350 K

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

\frac{500ml}{V_2}=\frac{150K}{350K}

V_2=1166.67ml

Therefore, the final volume of the gas is, 1166.67 ml

<span>pv=nrt; Pressure and moles are constant. p=nr(150k)/.5 L; Pressure initially After temp change pv=nrt; What is volume? v=nr(350k)/p; p is constant so we can substitute from above v=nr(350k)/(nr(150k)/.5 L)) v=350/150/.5 L v=4.66 liters</span>

Why can’t you see the stars very well at night like you could 50 years ago
Elenna [48]

Answer:Artificial light from cities has created a permanent "skyglow" at night, obscuring our view of the stars. Here's their map of artificial sky brightness in North America, represented as a ratio of "natural" nighttime sky brightness. In the black areas, the natural night sky is still (mostly) visible.

Carbon and oxygen combine to form carbon dioxide. What are the products, or what is the product, in this chemical reaction?
VladimirAG [237]

The product in this chemical reaction is Carbon Dioxide or CO2.

This is because it states, "To form," which means that it was produced from the reactants Carbon and Oxygen.

To know what the products are in a statement rather than an equation, words such as produced and formed are used.

Hope this helps!

3 A soil has 70% sand, 20% silt
Kisachek [45]

Today, as part of the series of posts on soils, we are going to look at ‘soil texture’. Soil forms the basis for all life but it’s important to know about its mineral constitution as well as its biological profile.

Texture refers to the ‘feel’ of the soil. This is affected by the constituent materials found within it, specifically sand, silt and clay particles. A coarse sand will feel gritty but a wet clay will feel heavy and sticky. The texture of a soil has a direct impact on the way the soil reacts to certain environmental conditions – for example, towards drought or heavy rain (with sandy soils more freely draining).

There is a big difference in the size of the different particles.

Coarse sand = diameter 2-0.2mm

Fine sand = diameter 0.2-0.02mm

Silt = diameter 0.02-0.002mm

Clay = diameter less than 0.002mm

Note how the clay particles are much smaller than the sand particles – this is important as it means the total surface area of a clay soil is much greater and so the capacity to hold water is also much greater.

Between the sand, silt and clay particles there are lots of pores. In fact a soil as a whole is generally 45% mineral, 5% organic matter (depending on the soil) and 50% pore space through which air and water can pass.

Sand –

Made up of weathered primary rock minerals.

The particles are irregular in outline.

They are large and so do not pack together easily.

Large pore spaces in between.

Air gets in very easily and water flows rapidly through it.

Silt –
