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

How are the nervous systems of a flatworm and a fish different?
A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.
Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.

A client is 45 years old and has a resting heart rate of 75 bpm issa.
The target heart rate of the 45 year old client with a resting heart rate of 75 bpm is; 135 bpm
Complete question is;
A client is 45 years old and has a resting heart rate of 75 bpm using the karvonen formula what is their target heart rate at an exercise intensity of 60%.
We are given;
Age of client = 45 years
Resting Heart rate = 75 bpm
%Intensity = 60%
The karvonen formula is;
Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR
Formula for maximum heart rate is;
Max HR = 220 - age
Max heart rate = 220 - 45
Max HR = 175 bpm
Thus;
Target Heart rate = [(175 - 75) × 0.6] + 75
Target Heart rate = (100 × 0.6) + 75
Target Heart rate = 60 + 75
Target Heart rate = 135 bpm

Answer:
Valence electrons in an atom of phosphorus in the ground state are found in 3rd shell.
Explanation:
Phosphorus has an atomic number of 15. Its electronic configuration is 2, 8, 5. This configuration implies that, phosphorus electrons are distributed in three different shells and the number of electrons in the outermost shell, which is the third shell, is 5. The ground state refers to a state, where the atoms of phosphorus are not excited. Electrons move away from their ground states when they are excited.
