You exhale about .0800 liters of CO2 (carbon dioxide) gas in a single breath. 22.4 liters of CO2 contain 6.022 x 1023 molecules.

6,022 x 1023 CO2 molecules have a mass of 44.0 grams. Find the A) number of carbon dioxide molecules you exhale in each breath. Find the mass of the CO2 you exhale in a single breath.

Answer:

A) 2.150 * 10^{22}

B) 1.57 grams

Explanation:

Given -

Amount of gas exhaled in one single breathe = 0.080 liters

22.4 liter of carbon dioxide contains 6.022 * 10^{23} molecules

One liter of carbon dioxide contains = \frac{6.022*10^{23}}{22.4}\\= 2.688 * 10^{23}

A) Number of molecules in 0.08 liter of carbon dioxide = 0.08 * 2.688 * 10^{23}\\= 2.150 * 10^{22}

B) Mass of 6.022 * 10^{23} molecules is equal to 44 grams

Mass of one molecule = \frac{44}{6.022*10^{23}} \\= 7.306*10^{-23}\\

Mass of molecule is[tex]7.306*10^{-23} * 2.150 * 10^{22}\\= 1.57\\[/tex]  gram

Fill in the word that best completes each sentence.
cupoosta [38]

Answer: Water is drawn in through small openings on a sponge's body called OSTIA.

The supportive skeleton of a sponge contains SPICULES which provide protection from predators.

Explanation:

Sponges refer to any of the aquatic animals of the phyllum porifera which is normally characterized with porous structures and has horn-like calcareous internal framework.

Sponges usually have multiple pores called "OSTIA" on their bodies that allow water to enter them.

Most sponges are sessile and because of this, they can't run away from predators. They usually have sharp "SPICULES" which are part of their skeleton that provide them some certain degree of defense. Apart from this, they also produce toxins which poisons predators that attempt to consume them

Solnce55 [7]

Their differences may eventually stop the separated squirrels from breeding with one another this is an example of  an Allopatric speciation

Explanation:

In allopatric speciation, species from the same population evolve some different characters due to the differences in geographical locations.

In this scenario, the species become reproductively isolated and diverge.

The mating times of the squirrel have changed due to the environmental changes.

They no longer interbreed and hence no viable offspring thus sexually isolated from each other.

Which describes the greenhouse effect? an artificial process a dangerous process a natural process a new process
Yuri [45]
The answer would be a dangerous process, this is because the greenhouse effect traps gasses such as CO2 and other harmful gasses emitted from the Earth, that can ultimately lead to problems in the future.

The greenhouse effect is also the reasoning behind why scientist believes in Global warming and climate change. 

Plus, the greenhouse effect is neither natural, new, nor artificial.
