Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate, and then release waste products.

b. Describe how the temperature changes within a phase and during a phase change as heat is added to a water sample. (2 points)

Rudik [331]

Hello!

Take for example the heating of water.

When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.

But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat.

Have a nice day!

A gas sealed in a drum container occupies 7.70 L at a sizzling 325C degrees. What will the volume be if the drum is quickly chi

grigory [225]

The volume of the drum after chilled quickly is 3.6 L.

<u>Explanation:</u>

As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.

$$\frac{V1}{T1} = \frac{V2}{T2} \\$

After chilling the drum, the volume will get reduced and it can be found as,

V2 = $$\frac{V1T2}{T1}$

= $$\frac{7.7 L \times 282 K}{598 K}$

= 3.6 L

Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.

Determine whether the graph is that of a function by using the vertical-line test. If it is, use the graph to find (a) its domai

Ilia_Sergeevich [38]

Answer:

Following are the solution to this question:

Explanation:

If the draw a line perpendicular with y-axis thru the diagonal line check but it meets only one curved point, therefore the curve indicates a function not otherwise. They draw a vertical line perpendicular to the y-axis there, it just intersects one more chart point, which is why a graph is a feature:

In point a:

$\to Domain= [-\pi ,\pi ]\\\\\to Range = [-1,1]$

In point b:

Its y-axis length cut also by understanding the benefits of y-interception and the x-axis length gives the x-intercept.

$\to y-intercept = 1\\\\\to x-intercept = \frac{\pi}{2} ,- \frac{\pi}{2} \\\\$

In point C:

Every graph is y-axis symmetric because the left side of the column as well as the middle side of the graph is about the same.

A compound is analyzed and found to contain 22.10%Al, 25.40%P, and 52.50%O. What is the empirical formula of the compound?

Whitepunk [10]

Let the total mass of compound is 100g

The mass of each element will be

Al = 22.10 g

P = 25.40 g

O = 52.50 g

In order to determine the molecular formula we will calculate the molar ratio of the given elements

Atomic weight of Al : 27 g/ mol

Atomic weight of P : 3 1g /mol

Atomic weight of O : 16 g /mol

Moles of Al = mass / atomic mass = 22.10 / 27 = 0.819

Moles of P = mass / atomic mass = 25.40/ 31 = 0.819

Moles of O = mass / atomic mass = 52.50/ 16 = 3.28

Now we will divide the moles of each element with the lowest moles obtained to obtain a whole number ratio of moles of each element present

moles of Al = 0.819 / 0.819 = 1

moles of P = 0.819 / 0.819 = 1

moles of O = 3.28 / 0.819 = 4

So the empirical formula will be : AlPO4
