Answer:
Sgen = 0.0366 W/K
Explanation:
for the body:
∴ Q = - 336 W...rate of heat loss
∴ T surface = 35°C ≅ 308 K
the rate of entropy transfer from the body:
⇒ ΔS = - Q/Ts
for the enviroment:
⇒ ΔS = Q/Te
∴ assuming: T = Tenv = 25°C ≅ 298 K
resulting in a net variation in the universe:
⇒ Sgen = ΔS = Q/Tenviroment - Q/Tsurface = Q(Ts - Te)/Ts*Te
⇒ Sgen = (336( 308-298))/(308×298) = 3360 WK/91784 K² = 0.0366 W/K
<u>Answer:</u> The concentration of 
comes out to be 0.129 M.
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Hence, the concentration of comes out to be 0.129 M.
Answer:
Preparation and Standardization of 0.1 M Ferrous Ammonium...
Dissolve 40 g of ferrous ammonium sulfate in a previously cooled mixture of 40 ml of sulphuric acid and 200 ml of water.
Dilute with sufficient freshly boiled and cooled water to produce 1000 ml.
Standardize the solution in the following manner.
Explanation:
Answer:
In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.Neutralization reactions are the reaction between acid and base. The products formed are water and salt. It is called so because the acid and base neutralize each other to form water and salt.Hint: The neutralization reaction is the one in which an acid reacts with an equimolar amount of base to give salt and water. The example could be a reaction between any strong acid and a base. The sodium chloride formed is a result of neutralization reaction.

Inertia is resistance to changes in motion. Which means if you are at rest it takes an external force to get you moving. And once you are moving it takes an external force to change the direction of that motion.
<span>For a person doing gymnastics the point that is subject to the above statement is her center of mass (roughly her belly button) . </span>
<span>So for example, once you launch into the air, gravity is the only significant force on you. It keeps you from traveling out into space by pulling you down and the trajectory of your belly button is a parabola. Now there is nothing you can do with your muscles (internal forces) to change that trajectory, even though you can do twists & turns about the center of mass. The height and range of the parabolic trajectory is determined by the angle & speed at which you initially launch yourself.

</span><span>inertia is one of newtons laws of motion so an object in motion tends to remain in motion until another force acts upon it that is what newton said when you are doing a back hand spring it is easier to keep going then to stop

Hope this helps!!! :D
I love gymnastics!!!!</span>
