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. <u>This statement is TRUE. </u>

<h3>Further explanation </h3>

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.

Enter a balanced equation for the reaction between solid nickel(II)(II) oxide and carbon monoxide gas that produces solid nickel
velikii [3]

Answer: A balanced equation for the given reaction is NiO(s) + CO \rightarrow Ni(s) + CO_{2}(g).

Explanation:

The reaction equation will be as follows.

NiO(s) + CO \rightarrow Ni(s) + CO_{2}(g)

Number of atoms on the reactant side is as follows.

  • O = 2
  • C = 1

Number of atoms on the product side is as follows.

  • Ni = 1
  • O = 2
  • C = 1

Since number of atoms on both the reactant and product sides are equal. Hence, the reaction equation is balanced.

Thus, we can conclude that a balanced equation for the given reaction is NiO(s) + CO \rightarrow Ni(s) + CO_{2}(g).

A 7.12 L cylinder contains 1.21 mol of gas A and 4.94 mol of gas B, at a temperature of 28.1 °C. Calculate the partial pressure
GenaCL600 [577]

Answer:

P_A=4.20atm\\\\P_B=17.1atm

Explanation:

Hello!

In this case, since the equation for the ideal gas is:

PV=nRT

For each gas, given the total volume, temperature (28.1+273.15=301.25K) and moles, we can easily compute the partial pressure as shown below:

P_A=\frac{n_ART}{V} =\frac{1.21mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_A=4.20atm\\\\P_B=\frac{n_BRT}{V} =\frac{4.94mol*0.082\frac{atm*L}{mol*K}*301.25K}{7.12L} \\\\P_B=17.1atm

Best regards!

Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas?
telo118 [61]

Answer: Some of the chemical energy in natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.

Explanation:

The natural gas consists of chemicals, which when burn produces thermal energy. This thermal energy is utilized for heating or boiling water. The boiling water produces steam the steam tries to come out of the kettle thus makes sound over the kettle lid, the pressure created by steam while leaving kettle produces sound energy.

Aluminum has a density of 2.70 g/mL. Calculate the mass (in grams) of a piece of aluminum having a volume of 381 mL . Express yo
BaLLatris [955]
Multiply the volume by the density. 1 ml = 1 cm^3

1.11 g/cm^3 * 1 cm^3/mL * 386 mL = 428 g

All your units cancel out except for g which is what you would expect since you want units of mass.

What is the mass of 0.80 moles of Mg? (1 point)
Aneli [31]

Answer:

m = 19 grams

Explanation:

Given that,

No. of moles, n = 0.8

The molar mass of magnesium, M = 24.305 u

We need to find the mass of 0.80 moles of Mg. We know that given mass to the molar mass is equal to no of moles. Let the mass is m. So,

n=\dfrac{m}{M}\\\\m=n\times M\\\\m=0.8\times 24.305 \\\\m=19.444\ \text{grams}

or

m = 19 grams

So, the mass of 0.8 moles of Mg is 19 grams.
