An air mattress is filled with 16.5 moles of air. the air inside the mattress has a temperature of 295 k and a gauge pressure of 3.5 kilopascals. what is the volume of the air mattress? the volume of the air mattress is__liters.

Explanation:

According to ideal gas equation, product of pressure and volume equals n times R times T.

Mathematically,         PV = nRT

where       P = pressure

                 V = volume

                 n = number of moles

                 R = gas constant

                 T = temperature

Therefore, it is given that no. of moles is 16.5 mol, pressure is 3.5 kilopascal equals 0.035 atm (as 1 Kpa = 0.01 atm), temperature is 295 K and R = 0.082 .

Hence, calculate the volume as follows.

                                   PV = nRT

                                 V =

                                     = 11403.85 L

Hence, we can conclude that the volume of the air mattress is 11403.85 liters.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
