Hey there! Hello!

The best answer I can give to you is that it depends. It depends on the way that the volume is being increased and if it's being increased along with the mass. 

Volume represents the amount of space a substance, object, etc. takes up. Density represents the amount mass found in a given measurement of volume. Taking these definitions into account, we can see that volume directly correlates with the measurement of density. 

Think of two buckets, one with one gallon of a substance and the other with two gallons of a substance. Both samples of the substance will have the same density, since mass was being added in addition to volume. Take a look at the example:

Bucket 1:
Mass of Substance = 1kg
Volume of Substance = 3cm^3
Density of Substance= 1/3 kg/cm^3


Bucket 2:
Mass of Substance = 3kg
Volume of Substance = 6cm^3
Density of Substance= 3/6 kg/cm^3 = 1/3 kg/cm^3

If we simply add substance, the mass and volume will increase together at a fixed rate, meaning that the most simplified version of the density fraction will always be the same.
 
But there's another part to this. You can increase or decrease the temperature of a sample, making volume increase/decrease and the mass stay the same. When you evaporate water, it turns to steam, which takes up much more space than it did as water. But nothing has been created or destroyed, so the mass stays the same. This would make the density change along with the volume.

I hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)

Answer: The correct answer is -297 kJ.

Explanation:

To solve this problem, we want to modify each of the equations given to get the equation at the bottom of the photo. To do this, we realize that we need SO2 on the right side of the equation (as a product). This lets us know that we must reverse the first equation. This gives us:

2SO3 —> O2 + 2SO2 (196 kJ)

Remember that we take the opposite of the enthalpy change (reverse the sign) when we reverse the equation.

Now, both equations have double the coefficients that we would like (for example, there is 2S in the second equation when we need only S). This means we should multiply each equation (and their enthalpy changes) by 1/2. This gives us:

SO3 —>1/2O2 + SO2 (98 kJ)

S + 3/2O2 —> SO3 (-395 kJ)

Now, we add the two equations together. Notice that the SO3 in the reactants in the first equation and the SO3 in the products of the second equation cancel. Also note that O2 is present on both sides of the equation, so we must subtract 3/2 - 1/2, giving us a net 1O2 on the left side of the equation.

S + O2 —> SO2

Now, we must add the enthalpies together to get our final answer.

-395 kJ + 98 kJ = -297 kJ

Hope this helps!

A dialysis unit requires 70000 mL of distilled water. How many gallons of water are needed? (1 gal = 4 qt)
crimeas [40]

Answer: 19.25 gallons

Explanation: 1 ml = 0.0011 quart

Given:  4 quarts = 1 gallon

Thus if 1 ml is equal to 0.0011 quart

70000 ml  is equal to =\frac{0.0011}{1}\times 70000=77quart

Now if 4 quarts is equal to 1 gallon.

77 quarts is is equal to=\frac{1}{4}\times 77=19.25gallons

Which color of light is diffracted at a greater angle from a diffraction grating, red or yellow?
Anit [1.1K]
The color of light that will be diffracted at a greater angle from a diffracting grating is THE YELLOW COLOR.
This is because, the degree of diffraction depend on the wavelength of light and light color with shorter wavelength are diffracted at a larger angle than those with longer wavelengths. The wavelength of the yellow color is much more smaller than that of the red color.
