Endorphins are generated in the body during exercise, which leads to better emotional health. Please select the best answer from the choices provided.a. True
b. False

Answers

Answer: Yes the statement is true.

Explanation: Endorphins are chemicals produced by the human bodies to relieve stress and pain.

They are produced mainly by brain and help to transmit electrical signals within nervous system, thus are called as neurotransmitters.

They are also called as "feel good chemicals" as they can act as pain relievers and happiness booster and thus lead to better emotional health.

Endorphins are generated in the body during exercise, which leads to better emotional health. This statement is TRUE.

Further explanation

Endorphins are chemicals produced by the body to relieve stress and pain. This chemical works similarly to a class of drugs called opioid. But because endorphins release naturally by the body it is a safer way to relieve stress and pain.  

Exercise boosted mood and powerful depression fighter for several reasons. Through exercise, you are not only gain your physical fitness but it also gives you an enormous sense of well being. You feel more energetic, positive, sleep well and  have better memory. Exercise can also serve as a distraction from negative thoughts and activities that feed depression.

Regular exercise is important to maintain a healthy body and mind. The recommended amount and intensity of physical activity varies according to ages and health condition. For an adult, the recommended time is 150 minutes per week for a moderate-intensity activity or 75 minutes per week for vigorous-intensity activity, or a combination of these two activities. You can break this into 25 minutes a day for 3 days a week.

Which of the following solutions contains the greatest number of ions?. . 1) 200.0 mL of 0.10 M iron (III) chloride. 2) 800.mL of 0.10 M sucrose

Answers

The number of ions is determined by multiplying the given volume and the molarity of the solution. The product is multiplied to the number of ions when the solution dissociates. In this case:

1. 200.0 mL of 0.10 M iron (III) chloride = 0.2*0.1* 4 = 0.08
2. 800.mL of 0.10 M sucrose = 0.8 * 0.1 * 1 = 0.08

The two solutions have the same number of ions. 

Under which conditions of temperature and pressure would a 1-liter sample of a real gas behave most like an ideal gas?(1) 100 K and 0.1 atm
(2) 100 K and 10 atm
(3) 500 K and 0.1 atm
(4) 500 K and 10 atm

Answers

Answer : The correct option is (3) 500 K and 0.1 atm.

Explanation :

A real gas behaves ideally at high temperature and low pressure.

The ideal gas equation is,

PV=nRT

where,

P = pressure of gas

V = Volume of gas

R = Gas constant

T = temperature of gas

n = number of moles of gas

The ideal gas works properly when the inter-molecular interactions between the gas molecules and volume of gas molecule will be negligible. This is possible when pressure is low and temperature is high.

Therefore, the correct option is (3) 500 K and 0.1 atm.

Answer:

The correct answer is (3).

Explanation:

A real gas can behave ideally at high temperatures and low pressures. The ideal gas is correctly characterized when the intermolecular interactions between the gas molecules and the volume of the gas molecule are negligible. This is only possible when system conditions are at low pressures and high temperatures.
