You have 41.6 g of O2 gas in a container with twice the volume as one with CO2 gas in another container. The pressure and temper

prisoha [69]

Answer:

The mass of carbon dioxide is 28.6 grams

Explanation:

Step 1: Data given

Mass of O2 = 41.6 grams

Volume of the O2 container = 2V

Volume of the CO2 container = V

Pressure and temperature are the same

Step 2: Ideal gas law

The ideal gas law = p*V=nRT

For O2: p*2V = n(O2)*R*T

For CO2: p*V = n(CO2)*R*T

n(O2)*R*T / P*2V = n(CO2)*R*T / P*V

Since P, R and T are contstant, we can simplify this to:

n(O2)/2 = n(CO2)

Step 3: Calculate moles of O2

Moles O2 = mass O2/ Molar mass O2

Moles O2 = 41.6 grams / 32 g/mol

Moles O2 = 1.3 mol O2

The number of moles CO2 = 0.65 mol

Mass of CO2 = Moles CO2 * Molar Mass CO2

Mass of CO2 = 0.65 mol * 44.01 g/mol

Mass of CO2 = 28.6 grams

The mass of carbon dioxide is 28.6 grams

Compare the strength of intermolecular forces in no2 to the strength of intermolecular forces in n2

matrenka [14]

N2 is non-polar molecules,
NO2 is polar molecules that have slightly positive charge on N and slightly negative on O, so intermolecular forces are stronger in NO2

An invasive species is a species that disrupts the ecosystem into which it is introduced by displacing species.

sveta [45]

Invasive species can do all sorts of damage to an existing ecosystem, including changing habitats and starving native animals of food and resources.

<h3>What is an invasive species?</h3>

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitats for native wildlife.

How are muscles able to keep making energy even when no food is eaten and glucose levels are low?

erastova [34]

Although lipids hold the majority of the body's energy reserves, glycogen is the body's primary energy source.

Glucose is a polymer that makes up glycogen. Our body's primary source of energy is carbs. The remaining glucose in the body is turned into glycogen and stored in various places, but the majority of our body's energy reserves are found in fats, which are kept in the form of lipids.

Where does the energy come from in the muscles?

The chemical energy that is stored in our meals is used by muscles to produce heat and motion energy (kinetic energy). Energy is necessary for maintaining body temperature, promoting physical activity, and enabling tissue growth and repair. Foods high in protein, fat, and carbohydrates provide energy.

What Takes Place to Muscles in the Absence of Glucose?

Your body converts carbs, such as those found in bread or fruit, into glucose after consumption. Glycogen is the form of glucose that is stored in your muscles and liver and is used for energy when you are not eating or while you are exercising.
